    Best Cartage, Inc. (“Best Cartage”) and National Interstate
    Insurance Co. (collectively “Defendants”) appeal from the Opinion
    and   Award    of    the   North   Carolina    Industrial   Commission   (“the
    Commission”)        awarding   James     Williams   (“Plaintiff”)   workers’
    compensation benefits with respect to his left knee injury.                 On
    appeal, Defendants contend that the Commission erred in (1) failing
    to specifically determine the reason for Plaintiff’s fall; and (2)
    concluding that Plaintiff’s left knee injury was causally related
    to his work-related accident and, therefore, compensable.                After
    careful review, we affirm the Commission’s Opinion and Award.
    Factual Background
    Plaintiff was employed as a long-haul semi-truck driver for
    Best Cartage.         At approximately 6:00 a.m. on 4 October 2011,
    Plaintiff parked his truck on an unpaved portion of the parking
    lot of a Huddle House restaurant in Bishopville, South Carolina,
    intending to have breakfast there.            As he opened the driver’s side
    door and began to exit the cab, Plaintiff’s left foot “unexpectedly
    landed in a hole or on some loose gravel,” and his left knee
    twisted.      Plaintiff then fell to his right toward the truck and
    also twisted his right knee.           He felt immediate pain in both knees
    with the pain in his left knee being more acute.             Later that day,
    Plaintiff returned to Best Cartage’s base office in Kernersville,
    North Carolina and reported the incident.
    -3-
    On the following day, Best Cartage sent Plaintiff to PrimeCare
    in Kernersville for a medical examination. At PrimeCare, Plaintiff
    was treated by Dr. Camille Andy (“Dr. Andy”) who diagnosed him
    with a “left medial knee sprain and degenerative joint disease,
    and right knee pain.”
    On 17 October 2011, Plaintiff filed a Form 18 “Notice of
    Accident to Employer and Claim of Employee.”          On 26 October 2011,
    Defendants responded by submitting a Form 61 “Denial of Workers’
    Compensation Claim.”      On 31 October 2011, Plaintiff moved to have
    his claim assigned for hearing.
    On 14 December 2011, Plaintiff saw Dr. Scott Dean (“Dr.
    Dean”), an orthopedist, regarding his left knee pain.             Dr. Dean
    recommended that Plaintiff undergo a total knee replacement of the
    left knee.   Dr. Dean performed left total knee replacement surgery
    on Plaintiff on 13 March 2012.         During his deposition, Dr. Dean
    testified    to   a   reasonable    degree   of   medical   certainty   that
    Plaintiff’s left knee injury was causally related to his 4 October
    2011 accident.
    The matter was heard before Deputy Commissioner Robert J.
    Harris on 12 March 2013.           Deputy Commissioner Harris filed an
    opinion and award on 28 August 2013, finding that Plaintiff’s left
    knee injury was causally related to the 4 October 2011 incident.
    He determined that Plaintiff was therefore entitled to all medical
    expenses incurred, or to be incurred, as a result of the injury.
    -4-
    Defendants appealed to the Full Commission.            On 27 May 2014,
    the   Commission   issued   an   Opinion     and   Award    affirming   Deputy
    Commissioner    Harris’s    opinion    and    award   and    concluding,   in
    pertinent part, as follows:
    Plaintiff sustained a compensable injury by
    accident to his left knee arising out of and
    in the course of his employment with
    defendant-employer upon the occurrence of the
    4 October 2011 incident, which injury caused
    a compensable exacerbation of plaintiff’s pre-
    existing left knee arthritis condition.
    Defendants filed a timely notice of appeal to this Court.
    Analysis
    Our review of an opinion and award by the Commission is
    “limited to consideration of whether competent evidence supports
    the Commission’s findings of fact and whether the findings support
    the   Commission’s   conclusions      of   law.”      Richardson   v.   Maxim
    Healthcare/Allegis Grp., 
    362 N.C. 657
    , 660, 
    669 S.E.2d 582
    , 584
    (2008). The Commission’s findings of fact are conclusive on appeal
    if supported by competent evidence even if there is evidence to
    support contrary findings.       Avery v. Phelps Chevrolet, 
    176 N.C. App. 347
    , 353, 
    626 S.E.2d 690
    , 694 (2006).            On appeal, this Court
    will not “weigh the evidence and decide the issue on the basis of
    its weight.     The court’s duty goes no further than to determine
    whether the record contains any evidence tending to support the
    finding.”     Smith v. Champion Int’l, 
    134 N.C. App. 180
    , 182, 517
    -5-
    S.E.2d 164, 166 (1999) (citation and internal quotation marks
    omitted).
    I. Nature of Accident
    In their first argument on appeal, Defendants challenge the
    Commission’s finding of fact 11, which states as follows:
    Plaintiff did acknowledge that, as a truck
    driver he would have to expect to step down
    onto different surfaces, such as pavement,
    sand or gravel, when getting out of his truck.
    Plaintiff also acknowledged that he was not
    sure exactly what his left foot had stepped on
    or in when this incident occurred. However,
    the Commission finds that the incident was an
    unexpected departure from plaintiff’s usual
    work routine and/or was an unexplained fall.
    The Commission finds that the circumstances of
    plaintiff’s   injury   on   4   October   2011
    constituted an interruption of his normal work
    routine and the introduction thereby of
    unusual circumstances likely to result in
    unusual results and/or was an unexplained
    fall. As such, on 4 October 2011, plaintiff
    sustained an injury by accident arising out of
    and in the course of his employment with
    defendant-employer.
    (Emphasis added.)
    Defendants take issue with the Commission’s use of the term
    “and/or,” asserting that the Commission “has not made specific
    findings    as   to   the   crucial   facts   that   are   required   for   a
    determination of whether Plaintiff is entitled to Compensation.”
    They further contend that the Commission’s “refusal to make a
    specific determination with regard to this crucial fact falls short
    of its judicial obligations and warrants reversal or, in the
    -6-
    alternative, remand for a determination as to whether Plaintiff’s
    alleged injury constituted an interruption of his normal work
    routine due to what he stepped down on or an unexplained fall.”
    It   is   well   established     that   “[u]nder   the   Workers’
    Compensation Act, an injury is compensable if the claimant proves
    three elements:   (1) that the injury was caused by an accident;
    (2) that the injury was sustained in the course of the employment;
    and (3) that the injury arose out of the employment.”     Philbeck v.
    Univ. of Michigan, __ N.C. App. __, __, 
    761 S.E.2d 668
    , 671 (2014)
    (citation and internal quotation marks omitted).
    As an initial matter, we take this opportunity to note our
    disapproval of the Commission’s use of the term “and/or.”          See
    Gibson v. Cent. Mfrs. Mut. Ins. Co., 
    232 N.C. 712
    , 717, 
    62 S.E.2d 320
    , 323 (1950) (“[T]he Court has inferentially condemned the use
    of the term ‘and/or’ in statutes, and in verdicts in judicial
    proceedings.   Moreover, the annotators of reported cases, and the
    text writers indicate that much has been written in condemnation
    of the term ‘and/or.’   It is declared, in effect, that the courts
    generally hold that the term ‘and/or’ has no place in judicial
    proceedings, pleadings, verdict or judgment.” (citation omitted));
    Gordon v. State Farm Mut. Auto. Ins. Co., 
    6 N.C. App. 185
    , 188,
    
    169 S.E.2d 514
    , 516 (1969) (“We do not look with favor upon the
    ambiguous and uncertain term ‘and/or.’” (citation and internal
    quotation marks omitted)).
    -7-
    Here, the Commission’s use of the term “and/or” compels us to
    read the provisions of finding of fact 11 containing this term in
    both the conjunctive and the disjunctive.           See State ex rel. N.C.
    Utils. Comm’n v. McKinnon, 
    254 N.C. 1
    , 13, 
    118 S.E.2d 134
    , 143
    (1961) (explaining that the “oft condemned and ambiguous term
    ‘and/or’   .   .   .   contains   both   the   conjunctive   ‘and’   and   the
    disjunctive ‘or.’”).       Therefore, under this construction, we read
    finding of fact 11 as a determination by the Commission that
    Plaintiff’s injury was the result of (1) an unexpected departure
    from Plaintiff’s usual work routine; (2) an unexplained fall; or
    (3) both an unexpected departure from Plaintiff’s usual work
    routine and an unexplained fall.         See Local Div. 589, Amalgamated
    Transit Union, AFL-CIO, CLC v. Com. of Mass., 
    666 F.2d 618
    , 627
    (1st Cir. 1981) (“[T]he words ‘and/or’ commonly mean ‘the one or
    the other or both.’”), cert. denied, 
    457 U.S. 1117
    , 
    73 L.Ed.2d 1329
     (1982).
    Significantly, Defendants do not argue that there is no
    competent evidence in the record to support either of these two
    theories of compensability.         Rather, they simply argue that the
    Commission was required to identify a single cause of Plaintiff’s
    injury and make a finding to that effect in its Opinion and Award.
    However, Defendants have failed to cite any caselaw specifically
    supporting their argument that the Commission’s failure to do so
    requires a remand.       As such, while we agree that the far better
    -8-
    practice would have been for the Commission to make a finding as
    to one specific cause of Plaintiff’s injury, we cannot hold that
    its failure to do so on these facts constituted reversible error
    unless one or both of the two theories identified by the Commission
    are   insufficient   to   establish   compensability   under   the   Act.
    Therefore, we must address each of the two theories set out in
    finding of fact 11.
    It is well settled that an unexpected departure from an
    employee’s normal work routine arising out of and in the course
    and scope of his employment resulting in injury represents one
    theory of compensability under the Act.
    The terms “accident” and “injury” are separate
    and distinct concepts, and there must be an
    “accident” that produces the complained-of
    “injury” in order for the injury to be
    compensable.   An “accident” is an “unlooked
    for event” and implies a result produced by a
    “fortuitous cause.” If an employee is injured
    while carrying on the employee’s usual tasks
    in the usual way the injury does not arise by
    accident. In contrast, when an interruption
    of the employee’s normal work routine occurs,
    introducing unusual conditions likely to
    result   in   unexpected    consequences,   an
    accidental cause will be inferred.         The
    “essence” of an accident is its “unusualness
    and unexpectedness.”
    Thus, in order to be a compensable “injury by
    accident,” the injury must involve more than
    the employee’s performance of his or her usual
    and customary duties in the usual way.

    Gray v. RDU Airport Auth., 
    203 N.C. App. 521
    , 525-26, 
    692 S.E.2d 170
    , 174 (2010) (internal citations, quotation marks, brackets,
    and ellipses omitted).
    However, this Court has held that if an employee’s injury is
    caused by a fall occurring during the course and scope of his
    employment “[i]t is not essential that there be evidence of any
    unusual or untoward condition or occurrence causing [the] fall
    which produces injury.   The fall itself is the unusual, unforeseen
    occurrence which is the accident.     A fall is usually regarded as
    an accident. . . . [A]n injury that is the result of a fall, which
    itself stems from an event that results from both the employee’s
    normal work routine and normal conditions, may still constitute an
    ‘accident.’”   Hedges v. Wake Cty. Pub. Sch. Sys., 
    206 N.C. App. 732
    , 735, 
    699 S.E.2d 124
    , 126 (2010) (emphasis added), disc. review
    denied, 
    365 N.C. 77
    , 
    705 S.E.2d 746
     (2011).
    In addition, a second but related theory of compensability
    under the Act is that of the unexplained fall.
    In a workers’ compensation case, if the cause
    or origin of a fall is unknown or undisclosed
    by the evidence, we apply case law unique to
    unexplained fall cases.       When a fall is
    unexplained, and the Commission has made no
    finding   that    any   force    or  condition
    independent of the employment caused the fall,
    then an inference arises that the fall arose
    out of the employment.      This inference is
    permitted because when the cause of the fall
    is unexplained such that there is no finding
    that any force or condition independent of the
    employment caused or contributed to the
    -10-
    accident, the only active force involved is
    the employee’s exertions in the performance of
    his duties.
    Philbeck,    __     N.C.    App.    at   __,      761    S.E.2d    at     672    (internal
    citations, quotation marks, brackets, and ellipses omitted).
    Thus, while finding of fact 11 is hardly a model of clarity,
    the Commission determined that the evidence supported one or both
    of two recognized theories of compensability.                             Therefore, we
    conclude that remand is not necessary.
    II. Causal Relationship
    Defendants       next       contend    that        insufficient      evidence     was
    introduced     to     support      the     Commission’s           determination       that
    Plaintiff’s left knee injury was causally related to his 4 October
    2011 accident.         Defendants contend that Dr. Dean’s opinion on
    causation was (1) impermissibly speculative; and (2) based upon
    the logical fallacy of post hoc, ergo propter hoc.                              We address
    each of these arguments in turn.
    A. Causation Testimony of Dr. Dean
    When the Commission relies on expert medical testimony, the
    expert’s testimony “must be such as to take the case out of the
    realm of conjecture and remote possibility” in order to constitute
    competent evidence of a causal relationship between the work-
    related     accident       and    the    injury.          Rogers     v.    Lowe’s     Home
    Improvement, 
    169 N.C. App. 759
    , 765, 
    612 S.E.2d 143
    , 147 (2005)
    (citation and internal quotation marks omitted).                     A medical expert
    -11-
    [s]tating an accident “could or might” have
    caused an injury, or “possibly” caused it is
    not generally enough alone to prove medical
    causation;   however,   supplementing   that
    opinion with statements that something “more
    than likely” caused an injury or that the
    witness is satisfied to a “reasonable degree
    of medical certainty” has been considered
    sufficient.
    Carr v. Dep’t of Health & Human Servs., 
    218 N.C. App. 151
    , 155,
    
    720 S.E.2d 869
    , 873 (2012).
    Defendants contend that no competent evidence existed to
    support the Commission’s findings of fact 5, 21, 25, and 26.   These
    findings state as follows:
    5. Long before the 4 October 2011 incident
    that is the basis of this claim, plaintiff had
    bilateral degenerative joint disease in both
    of his knees.    His bilateral knee condition
    had been diagnosed as end-stage, bone-on-bone
    osteoarthritis.    Plaintiff had undergone a
    right-sided total knee replacement in about
    2004. However, since starting with defendant-
    employer in 2007, he had been able to do his
    job without difficulty.
    21. As Dr. Dean confirmed in his testimony, he
    believed that the 4 October 2011 incident
    exacerbated plaintiff’s pre-existing left
    knee arthritis condition.        As Dr. Dean
    testified, the 4 October 2011 incident was the
    straw that broke the camel’s back for
    plaintiff’s left knee condition and sent it on
    a   downward   spiral   to   the   total  knee
    replacement. Dr. Dean provided this causation
    opinion taking into account plaintiff’s
    history, plaintiff’s prior complaints in 2009
    of left knee pain, his own objective findings,
    and his experience gained through 20 years of
    practice in sports medicine.      As Dr. Dean
    noted, he had seen minimal trauma cause this
    scenario before.
    -12-
    25. The medical treatment that plaintiff has
    received for his left knee condition since 4
    October 2011 has been reasonably required to
    effect a cure, provide relief, and/or lessen
    the period of plaintiff’s disability.
    26. Further medical treatment for plaintiff’s
    left knee condition is reasonably required to
    effect a cure and/or provide relief for his
    left knee condition.
    Defendants further challenge the Commission’s conclusions of
    law 1, 3, and 4:
    1. Plaintiff sustained a compensable injury by
    accident to his left knee arising out of and
    in the course of his employment with
    defendant-employer upon the occurrence of the
    4 October 2011 incident, which injury caused
    a compensable exacerbation of plaintiff’s
    preexisting left knee arthritis condition.

    __, 
    705 S.E.2d 746
     (2011).
    3. Plaintiff is entitled to have defendants
    pay for the medical treatment that he has
    received for his compensable left knee
    condition since 4 October 2011, including, but
    not limited to, the diagnostic testing and
    imaging, injections, prescriptions, surgery,
    hospitalization, physical therapy and mileage
    that plaintiff underwent or incurred while
    under the care of Dr. G. Scott Dean.

    4. Plaintiff is entitled to have Dr. G. Scott

    this claim and to have defendants authorize
    and pay for the treatment that Dr. Dean
    recommends for plaintiff’s compensable left
    knee condition, including, but not limited to,
    diagnostic testing and imaging, physical
    therapy,   pain   management,   prescriptions,
    -13-
    referrals and mileage.   
    Id.
    Defendants challenge the portion of finding of fact 5 stating
    that “since starting with defendant-employer in 2007, he had been
    able to do his job without difficulty,” arguing that “[t]here is
    no evidence of record suggesting that Plaintiff had been able to
    do his job without difficulty since 2007.”   However, they do not
    challenge findings of fact 4, 12, and 19.      Finding of fact 4
    establishes that “Plaintiff started [work] with defendant-employer
    as a long-haul semi-truck driver in 2007.”     Finding of fact 12
    states, in pertinent part, that one day after the accident, “Dr.
    Andy diagnosed [Plaintiff with] a left medial knee sprain and
    degenerative joint disease, and right knee pain. . . . [S]he wrote
    that plaintiff could return to sedentary work, with no lifting
    over five pounds, minimal walking and frequent position changes.”
    Finding of fact 19 states that approximately nine to ten weeks
    later, “Dr. Dean restricted plaintiff to primarily sedentary-type
    activity.”
    Thus, Defendants do not dispute the fact that Plaintiff was
    hired in 2007 and had been working as a truck driver from that
    date until the 4 October 2011 injury.    No evidence was presented
    that he was not able to do his job as a truck driver prior to 4
    October 2011.   Findings of fact 12 and 19 do establish, however,
    that beginning the day after his injury, Plaintiff was restricted
    by Dr. Andy from performing his normal duties as a truck driver
    -14-
    and again by Dr. Dean several weeks later.     While Defendants point
    to the deposition testimony of Dr. Donna Gates for the purpose of
    showing that Plaintiff had complained of left knee pain on 25
    November 2009 during a “wellness visit and a recheck of his chronic
    medical problems,” this evidence does not suggest that Plaintiff
    was unable to perform his job duties prior to the 4 October 2011
    accident.
    Therefore, while it is clear that Plaintiff had degenerative
    joint disease in his left knee prior to the 4 October 2011 injury,
    competent evidence exists in the record that the 4 October 2011
    incident    aggravated   his   left    knee   condition,   materially
    restricting his ability to work.      We have consistently held that
    [a] work-related injury need not be the sole
    causative   force   to   render    an   injury
    compensable.    When a pre-existing, non-
    disabling,   non-job-related    condition   is
    aggravated or accelerated by an accidental
    injury arising out of and in the course of
    employment so that disability results, then
    the employer must compensate the employee for
    the entire resulting disability.          This
    “aggravation rule” does not bar recovery if
    there is evidence of a causal connection
    between a claimant’s current disability and a
    prior condition.   It also does not require
    that claimant suffer from new or different
    symptoms from those of which he previously
    complained; rather, the claimant must only
    demonstrate that his work-related injury
    contributed in some reasonable degree to the
    disability.

    482 S.E.2d 34
    , 37 (1997) (internal citations, quotation marks, and
    ellipses omitted).
    Finding of fact 21 is supported by the testimony given by Dr.
    Dean during his deposition.   Indeed, finding of fact 21 largely
    tracks the following statements made by Dr. Dean:
    A. Again, it just — and I think I put this in
    the note that it’s kind of like the fall, sort
    of, didn’t necessarily cause the arthritis,
    but it sent him on the — it was the straw that
    broke the camel’s back. It sent him on the
    spiraling path downward, you know, as far as
    the — I have just seen that — I have seen that
    pattern before.
    . . . .
    Q. So the decision that that’s the straw that
    breaks the camel’s back, is because he’s
    telling you that’s when it started getting
    worse?
    A. Yes.
    . . . .
    Q. . . . If he had gotten out of the truck .
    . . and fell, would that still, kind of, start
    this downward spiral.
    A. I have seen minimal trauma like that cause
    this scenario.    I have seen that pattern
    before, yes.
    Q. So if it was a fall, regardless of — I mean,
    he — there was a gravel parking lot, and he
    misstepped [sic], or if there was a hole, or
    what actually caused the trigger of the fall,
    wouldn’t really — would it impact your
    decision?
    -16-
    A. My decision?
    Q. Or your opinion?
    A. About what really caused it?
    Q. Yes, sir.
    A. I mean, the mechanism of injury, you
    consider how much energy went into the fall,
    was it a fall from a height, was it just a
    stumble, was it a big impact? Some of that
    does, sort of, factor into does this all make
    sense with the pattern that I have seen before
    with, like, hundreds of other patients? So it
    does, kind of, factor into it. And I think
    that in his knee, with end stage bone on bone
    arthritis, it would not take very much at all
    to, kind of, tip him over the edge.
    Findings of fact 25 and 26 are also supported by the testimony
    of Dr. Dean.
    Q. Dr. Dean, you first saw [Plaintiff] for
    left knee pain on December 14th, 2011, is that
    correct?
    A. (The witness reviews notes.) Yes.
    . . . .
    Q. The next time [Plaintiff]      saw   you   was
    January 6th of 2012?
    A. (The witness reviews notes.) Yes.
    Q. Excuse me. What complaints did [Plaintiff]
    have when you saw him on January 6th?
    A. (The witness reviews notes.) On January
    6th, he had reasonable relief from the left
    knee injection performed in December of 2011,
    but it was starting to wear off.
    . . . .
    -17-
    Q. . . . What recommendations for treatment
    did you make regarding [Plaintiff’s] left knee
    at that time?
    A. On the 6th, I thought his left knee was
    improved with an injection.     He did have
    pretty severe arthritis. I thought he might
    need a knee replacement in the future.     I
    refilled his Vicodin, which is a pain
    medicine, and I was going to see him back in
    six months.
    . . . .
    Q. And what was your plan at that appointment
    for treating [Plaintiff]?
    A. Left knee replacement.
    Q. And in fact, you performed a left knee
    replacement on March 13th, 2012, is that
    correct?
    A. Yes.
    . . . .
    Q. Dr. Dean, approximately how many knee
    replacements do you do in a given year? A
    ballpark estimate is fine.
    A. Probably 50 to 100.
    Q. And in your experience, does a total knee
    replacement  last   the   lifetime  of   the
    recipient?
    A. No.
    Q. How long does it typically last?
    A. Depending on the age and activity level and
    weight of the patient, maybe 10 year [sic].
    Q. And when a total knee replacement wears
    out, what’s the recommended method for
    treating that?
    -18-
    A. Typically, it has to be revised, based on
    the reason that it has worn out.
    Dr. Dean’s testimony also supports findings of fact 25 and 26
    in that it details the history of his treatment of Plaintiff’s
    knee    and     Dr.   Dean’s      accompanying      diagnoses   and   medical
    recommendations.             Furthermore,     Dr.   Dean’s   testimony    that
    Plaintiff’s left knee replacement was not a permanent solution and
    that his left knee issues would in all likelihood need to be
    addressed again in approximately 10 years supports finding of fact
    26 by showing that further future medical treatment for Plaintiff’s
    left knee condition will be necessary.
    Defendants     next    argue   that    Dr.   Dean’s   stated   opinions
    concerning Plaintiff’s left knee injury were based solely upon
    speculation and conjecture.           In making this argument, Defendants
    point to the following exchange in his deposition:
    Q. Dr. Dean, I would like to ask that you
    consider the following assumption. Assuming
    that prior to October 4th, 2011 [Plaintiff]
    was asymptomatic with regards to his left
    knee,   and   that  on   October   4th,   2011
    [Plaintiff] stepped into a hole climbing out
    of the cab of his semi truck causing him to
    fall, and thereafter he had swelling, pain,
    and grinding — reports of a grinding sensation
    and a feeling of instability in his left knee.
    Assuming those facts, in your opinion, to a
    reasonable degree of medical certainty, did
    the event of October 4th, 2011 aggravate or
    accelerate the condition in [Plaintiff’s] left
    knee for which you operated on him on March
    13th, 2012?
    -19-
    [Defendants’ counsel]: Objection.                 You
    can go ahead.
    A. Yes.    And I think that was stated in the
    chart.
    Defendants assert that this portion of his testimony was
    premised upon the following three assumptions:               (1) that Plaintiff
    was asymptomatic prior to 4 October 2011; (2) that Plaintiff
    stepped into a hole when he exited his tractor trailer and fell as
    a result of doing so; and (3) that Plaintiff had swelling, pain,
    and a grinding sensation as a result of the fall.               Defendants also
    contend that this testimony served as the sole basis for Dr. Dean’s
    opinion on causation and, therefore, if any of these assumptions
    are unsupported by competent evidence, then Dr. Dean’s testimony
    is   insufficient     to     establish      a    causal    connection     between
    Plaintiff’s injury and the 4 October 2011 accident.                     We reject
    Defendants’ argument.
    In   finding     of    fact   7   (a     finding     Defendants    have   not
    challenged), the Commission determined that when Plaintiff’s “left
    foot hit the ground, it unexpectedly landed in a hole or on some
    loose gravel or sand, and plaintiff’s left knee twisted.”                      In
    addition, finding of fact 8 — also unchallenged by Defendants —
    states that “Plaintiff felt immediate pain in both of his knees
    upon the occurrence of this incident.”
    Even   assuming       the   portion    of   the    hypothetical     question
    premised on Plaintiff having been asymptomatic prior to the 4
    -20-
    October 2011 incident was not supported by competent evidence, we
    do not believe that this renders Dr. Dean’s ensuing testimony
    incompetent on the causation issue.   It is well established that
    “[a] hypothetical question need only present sufficient facts to
    allow the witness to express an intelligent and safe opinion.   It
    [is] not incumbent on the plaintiff to include in his hypothetical
    questions all the evidence bearing upon the fact to be proved; the
    defendants ha[ve] the right to present other phases of the evidence
    in counter-hypothetical questions.”   Robinson v. J. P. Stevens &
    Co., 
    57 N.C. App. 619
    , 622-23, 
    292 S.E.2d 144
    , 146 (1982) (internal
    citations, quotation marks, and brackets omitted).
    During his cross-examination of Dr. Dean, Defendants’ counsel
    did, in fact, pose a counter-hypothetical question:
    Q.   And then if there — so if there was
    evidence to the contrary, if for example,
    there was a prior exam that showed bone on
    bone or if there was a prior diagnosis of end
    stage arthritis with associated pain, then
    that would be evidence that the fall didn’t
    cause [Plaintiff’s injury]?
    A. Again, it just — and I think I put this in
    the note that it’s kind of like the fall, sort
    of, didn’t necessarily cause the arthritis,
    but it sent him on the — it was the straw that
    broke the camel’s back. It sent him on the
    spiraling path downward, you know, as far as
    the — I have just seen that — I have seen that
    pattern before.
    On redirect examination, Dr. Dean then testified as follows:
    Q. You — when [Defendants’ counsel] was
    questioning you, we’ve talked about this, kind
    -21-
    of, the downward spiral and the trigger event
    for — or to, kind of, start somebody on that
    spiral. And I think you — I don’t want to put
    words in your mouth, but I think you indicated
    that with the arthritis that [Plaintiff] had
    that it wouldn’t take much to, kind of, start
    him on that spiral downward. If he had gotten
    out of the truck — regardless of whether there
    was a hole that he stepped in or not, but he
    got out of the truck, lost his balance, and
    fell, would that still, kind of, start this
    downward spiral?
    A. I have seen minimal trauma like that cause
    this scenario.    I have seen that pattern
    before, yes.
    We are satisfied that — taken as a whole — Dr. Dean’s opinion
    testimony was sufficient to establish causation.       As such, the
    Commission was entitled to rely upon his testimony that Plaintiff’s
    left knee injury was causally related to his 4 October 2011
    accident.
    B. Post Hoc, Ergo Propter Hoc
    Defendants also argue that Dr. Dean based his opinion on the
    post hoc, ergo propter hoc logical fallacy.    We disagree.
    The maxim “post hoc, ergo propter hoc,”
    denotes the fallacy of confusing sequence with
    consequence, and assumes a false connection
    between causation and temporal sequence. As
    such, this Court has treated the maxim as
    inconclusive as to proximate cause. . . . In
    a case where the threshold question is the
    cause of a controversial medical condition,
    the maxim of “post hoc, ergo propter hoc,” is
    not competent evidence of causation.

    353 N.C. 227
    , 232, 
    538 S.E.2d 912
    ,
    916 (2000) (internal citations, quotation marks, and ellipses
    omitted).
    Defendants’ argument on this issue is based on the following
    portion of Dr. Dean’s testimony:
    Q: So basically, [the pain] wasn’t there on
    day one, he alleges to have the injury on day
    two, on day three he has pain. So because it
    wasn’t there before and is there now, that’s
    how you identify the injury as being the
    cause?
    A: As, I think I called it, an exacerbating
    factor, yes.
    However, Dr. Dean also testified as follows:
    Q. And the, I guess, objective ability to view
    the joint and see if it’s bone on bone or if
    there is actual cushion there that could work?
    A. Yeah. It’s really just based on his — what
    he tells me and then objectively what the knee
    is telling me. . . .
    . . . .
    Q. And then if there — so if there was evidence
    to the contrary, if for example, there was a
    prior exam that showed bone on bone or if there
    was a prior diagnosis of end stage arthritis
    with associated pain, then that would be
    evidence that the fall didn’t cause it?
    A. Again, it just — and I think I put this in
    the note that it’s kind of like the fall, sort
    of, didn’t necessarily cause the arthritis,
    but it sent him on the — it was the straw that
    broke the camel’s back. It sent him on the
    spiraling path downward, you know, as far as
    the — I have just seen that — I have seen that
    pattern before.
    -23-
    . . . .
    Q. So the decision that that’s the straw that
    breaks the camel’s back, is because he’s
    telling you that’s when it started getting
    worse?
    A. Yes.
    . . . .
    Q. . . . If he had gotten out of the truck .
    . . and fell, would that still, kind of, start
    this downward spiral.
    A. I have seen minimal trauma like that cause
    this scenario.    I have seen that pattern
    before, yes.
    Q. So if it was a fall, regardless of — I mean,
    he — there was a gravel parking lot, and he
    misstepped [sic], or if there was a hole, or
    what actually caused the trigger of the fall,
    wouldn’t really — would it impact your
    decision?
    A. My decision?
    Q. Or your opinion?
    A. About what really caused it?
    Q. Yes, sir.
    A. I mean, the mechanism of injury, you
    consider how much energy went into the fall,
    was it a fall from a height, was it just a
    stumble, was it a big impact? Some of that
    does, sort of, factor into does this all make
    sense with the pattern that I have seen before
    with, like, hundreds of other patients? So it
    does, kind of, factor into it. And I think
    that in his knee, with end stage bone on bone
    arthritis, it would not take very much at all
    to, kind of, tip him over the edge.
    -24-
    We are satisfied that Dr. Dean’s determination that a causal
    connection   existed   between    the   4    October   2011      accident   and
    Plaintiff’s left knee injury was based on more than post hoc, ergo
    propter hoc reasoning.     We have held that where a medical expert
    relies upon something more than mere temporal sequence, a post
    hoc, ergo propter hoc issue does not exist.                 See Legette v.
    Scotland Mem’l Hosp., 
    181 N.C. App. 437
    , 456, 
    640 S.E.2d 744
    , 756
    (2007) (“[Doctor’s] opinion testimony was not based solely on the
    notion of post hoc ergo propter hoc.         [Doctor] also testified that
    Plaintiff’s description of the accident was consistent with a
    trauma of the type that would be associated with the development
    of lymphedema in someone with Plaintiff’s medical history.”),
    appeal dismissed and disc. review denied, 
    362 N.C. 177
    , 
    658 S.E.2d 273
     (2008); see also Carr, 218 N.C. App. at 156, 
    720 S.E.2d at 874
    (“[Doctor’s] opinion, however, was based on more than merely the
    sequence of events.       In his deposition, [Doctor] stated that
    although ‘a lot of it is based on timing,’ his opinion was based
    on the mechanism of injury as well as the temporal relationship
    between the incident and symptoms.”).
    In   the   present   case,   Dr.       Dean   relied   on    Plaintiff’s
    description of the accident and his objective diagnosis of the
    injury based upon his examination of “hundreds of other patients”
    in reaching his opinion to a reasonable degree of medical certainty
    that Plaintiff’s left knee injury was causally related to his 4
    -25-
    October   2011   accident.    Therefore,   we   reject   Defendants’
    contention that Dr. Dean relied solely on post hoc, ergo propter
    hoc reasoning in his opinion regarding causation.
    Conclusion
    For the reasons stated above, the Commission’s Opinion and
    Award is affirmed.
