ETHAN ALLEN, and ST. PAUL TRAVELERS, Defendants" ], "opinions": [ { "text": "STEELMAN, Judge.\nPlaintiff was required to prove, by expert medical testimony, that her right knee injury was a direct and natural result of her compensable left knee injury. This causal link was not established by plaintiffs expert witness. As to defendant\u2019s second argument, there is a conflict in the findings of the Industrial Commission, and this matter is remanded for additional findings of fact.\nI. Factual and Procedural Background\nIn July 2005, Linda.Weatherly Nale (plaintiff) was employed as an interior designer in Charlotte at Ethan Allen Interiors Inc. (Ethan Allen). Her duties included greeting people when they came to the store, going to clients\u2019 residences to deliver accessories, and picking up materials and supplies from the warehouse. Plaintiff was on her feet \u201cquite a bit,\u201d and \u201cwould walk quite a ways around into the store.\u201d\nOn 14 July 2005, plaintiff was in the warehouse searching for fabric when her left foot became wedged in between boxes. She fell forward and twisted her left knee. Plaintiff continued working without reporting the incident. That weekend, plaintiff went on vacation, and her pain \u201ccontinued to get worse____\u201d Plaintiff went to the emergency room upon her return to Charlotte.\nOn 26 July 2005, plaintiff went to Northcross Urgent Care in Huntersville complaining of left knee pain and a swollen, numb foot. Dr. Hal Armistead (Dr. Armistead) imposed work restrictions including wearing a splint, lifting no more than ten pounds,, and no stooping, bending or twisting. The work restrictions were delivered to plaintiff\u2019s manager, Michelle Jones (Jones) that same day. Plaintiff continued to work. Over the next several months, plaintiff saw four different doctors seeking treatment for her left knee.\nOn 13 September 2005, Ethan Allen completed Industrial Commission (Commission) Form 19 reporting plaintiff\u2019s left knee injury. On 16 September 2005, Ethan Allen\u2019s carrier filed a Form 61 with the Commission denying the claim, pending further investigation and receipt of medical records from all treating physicians. On 21 October 2005, Ethan Allen\u2019s carrier filed another Form 61 denying the claim based on plaintiff\u2019s failure to execute a medical authorization sheet listing her physicians and their contact information.\n\u2022 On 29 November 2005, Dr. Christopher Bensen (Dr. Bensen), an orthopaedic surgeon, directed that plaintiff not work until 12 December 2005. On 19 December 2005, Dr. Scott L. Smith (Dr. Smith), who practiced with Dr. Bensen, placed plaintiff on work restrictions \u201cwith sedentary work only with no walking more than 15 minutes an hour and no bending, stooping, squatting, or kneeling.\u201d Plaintiff was further restricted from climbing stairs or ladders.\nOn 24 August 2006, plaintiff sought treatment from Dr. H. Del Schutte, Jr. (Dr. Schutte). Dr. Schutte recommended arthroscopic surgery on plaintiffs left knee. On 7 September 2006, Dr. Schutte performed a chondroplasty, shaving loose or frayed cartilage from her knee. Dr. Schutte\u2019s surgical note stated that plaintiff had \u201csome injury to the cartilage and some fraying of her meniscus.\u201d Following surgery, plaintiff experienced a significant reduction in pain. Dr. Schutte encouraged her to be active, and she resumed running for exercise.\nThe Commission found that plaintiff voluntarily left her employment with Ethan Allen on 1 May 2006, drew unemployment compensation from that date, and returned to work on 28 December 2006. On 26 February 2007, plaintiff requested that her claim be assigned for hearing.\nOn 7 March 2007, plaintiff returned to Dr. Schutte complaining of pain in her left knee and that \u201cher left knee needs to be lubricated.\u201d X-rays taken of her left knee revealed \u201cmedial wear and joint space narrowing in the medial aspect with some bone spurs.\u201d Dr. Schutte injected her left knee with steroids.\nOn 9 May 2007, plaintiff returned to Dr. Schutte, complaining of pain in her right knee. Earlier that week, plaintiff twisted her right knee and \u201cfelt a pop.\u201d Dr. Schutte administered a cortisone injection. The injection relieved the pain until she tried to get into her vehicle and felt another pop in her right knee. On 16 May 2007, plaintiff told Dr. Schutte that her right knee had \u201cjust started hurting a few weeks ago,\u201d and she thought \u201cit [was] because her left knee had been hurting in the past.\u201d Plaintiff stated she had been placing more weight on her right knee.\nOn 26 June 2007, Dr. Schutte performed a chondroplasty and excision of plica on plaintiffs right knee. Plica is scar tissue on the inner lining of the capsule in the knee. Dr. Schutte also removed fluid from plaintiffs right knee. On 11 July 2007, Dr. Schutte opined that she had \u201ca greater than 50% chance of requiring bilateral total knee anthroplasties in the future.\u201d\nOn 10 September 2008, the Commission filed an Opinion and Award ruling that plaintiffs left knee injury was a compensable injury, and plaintiffs right knee condition was causally related to her compensable left knee injury. The Commission awarded plaintiff total disability compensation for 241 days based on an average weekly wage of $770.97, a total of $17,695.60 pursuant to N.C. Gen. Stat. \u00a7 97-29. Past, present, and future medical expenses related to her left and right knee injuries were also awarded.\nDefendants appeal.\nII.Standard of Review\nThis Court\u2019s standard of review of an Opinion and Award of the Industrial Commission is \u201cwhether there is any competent evidence in the record to support the Commission\u2019s findings of fact and whether these findings support the Commission\u2019s conclusions of law.\u201d Lineback v. Wake County Board of Commissioners, 126 N.C. App. 678, 680, 486 S.E.2d 252, 254 (1997) (citing Sidney v. Raleigh Paving & Patching, 109 N.C. App. 254, 426 S.E.2d 424 (1993)). The Commission\u2019s findings of fact are conclusive on appeal if supported by competent evidence. This is true even if there is evidence to support a contrary finding. Morrison v. Burlington Industries, 304 N.C. 1, 6, 282 S.E.2d 458, 463 (1981) (citations omitted). \u201cThe court\u2019s duty goes no further than to determine whether the record contains any evidence tending to support the finding.\u201d Adams v. AVX Corp., 349 N.C. 676, 681, 509 S.E.2d 411, 414 (1998) (quoting Anderson v. Construction Co., 265 N.C. 431, 434, 144 S.E.2d 272, 274 (1965)). In determining whether competent evidence supports the findings of fact, the evidence is to be viewed in the light most favorable to plaintiff. Davis v. Harrah\u2019s Cherokee Casino, 362 N.C. 133, 137, 655 S.E.2d 392, 395 (2008) (citations omitted). Plaintiff is entitled to the benefit of every reasonable inference to be drawn from the evidence. Id.\nIII.Left Knee Iniurv\nDefendants assigned error to the Commission\u2019s award pertaining to plaintiff\u2019s left knee injury but have failed to argue the assignment of error in their brief. It is thus deemed abandoned pursuant to N.C.R. App. P. 28(b)(6).\nIV.Right Knee Iniurv Not Causally Related to Left Knee Iniurv\nIn their first argument, defendants contend the Commission erred in finding that plaintiff\u2019s right knee injury was causally related to the compensable left knee injury. We agree.\nThe Worker\u2019s Compensation Act \u201cwas never intended to provide the equivalent of general accident or health insurance.\u201d Vause v. Equipment Co., 233 N.C. 88, 92, 63 S.E.2d 173, 176 (1951). An injury is only compensable if it arises \u201cout of and in the course of the employment.\u201d N.C. Gen. Stat. \u00a7 97-2(6) (2007). Plaintiff bears the-burden of proving each element of compensability. Holley v. ACTS, Inc., 357 N.C. 228, 234, 581 S.E.2d 750, 754 (2003) (citing Harvey v. Raleigh Police Dept., 96 N.C. App. 28, 35, 384 S.E.2d 549, 553, disc. rev. denied, 325 N.C. 706, 388 S.E.2d 454 (1989)). A subsequent injury is compensable if it is the direct and natural result of a compensable primary injury. As long as the primary injury is shown to have arisen out of and in the course of employment, then every natural consequence flowing from that injury likewise arises out of the employment. Starr v. Paper Co., 8 N.C. App. 604, 611, 175 S.E.2d 342, 347 (1970) (quoting Larson\u2019s Workmen\u2019s Compensation Law \u00a7 13.00). The subsequent injury is not compensable if it is the result of an independent, intervening cause. \u2018\u201cAn intervening cause is one occurring entirely independent of a prior cause. When a first cause produces a second cause that produces a result, the first cause is a cause of that result.\u2019 \u201d Cannon v. Goodyear Tire & Rubber Co., 171 N.C. App. 254, 260, 614 S.E.2d 440, 445 (2005) (quoting Petty v. Transport, Inc., 276 N.C. 417, 426, 173 S.E.2d 321, 328 (1970)), disc. review denied, 360 N.C. 61, 621 S.E.2d 177 (2005). \u201cTo show causal relation, \u2018the evidence must be such as to take the case out of the realm of conjecture and remote possibility, that is, there must be sufficient competent evidence tending to show a proximate causal relation ....\u2019\u201d Everett v. Well Care & Nursing Servs., 180 N.C. App. 314, 319, 636 S.E.2d 824, 828 (2006) (quoting Gilmore v. Board of Education, 222 N.C. 358, 365, 23 S.E.2d 292, 296 (1942)).\nDefendants contend that the evidence does not support the following findings of fact of the Commission:\n20. Plaintiff\u2019s left knee has continued to hurt since September 2006. Several weeks before May 2007, Plaintiff\u2019s right knee started to hurt more. By May 9, 2007, Plaintiff had twisted her right knee and felt a pop. Several days later, her knee popped again when her knee gave way while she was getting into her car.\n21. Dr. Schutte was of the opinion, and the Full Commission finds as fact, that Plaintiff\u2019s overcompensation of her knees caused problems with Plaintiff\u2019s right knee. Dr. Schutte state[d] specifically during deposition: \u201cI have ho doubt that her right knee was working hard[er] than her left knee, given that she has arthritis in her left knee and was favoring that knee.f\u201d] And Plaintiff testified that although she had no right knee problems prior to her work-related accident, she began to have right knee problems following the accident. Plaintiff stated at the hearing before the Deputy Commissioner: \u201c[B]ecause I had tried to shelter the left knee so much, I had made my right knee and my right leg bear all the weight.\u201d Based upon a review of the record in this matter, the Full Commission finds that the greater weight of the evidence shows that Plaintiffs overcompensation of her right side more than likely caused, contributed to, or aggravated the underlying pathology in Plaintiffs right knee to the point that her right knee became symptomatic.\n\u201cThe Commission is the sole judge of the credibility of the witnesses and the weight to be given their testimony.\u201d Anderson, 265 N.C. at 433-34, 144 S.E.2d at 274 (citations omitted). However, the Commission\u2019s findings of fact may be set aside on appeal when there is a complete lack of competent evidence to support them. Young v. Hickory Bus. Furn., 353 N.C. 227, 230, 538 S.E.2d 912, 914 (2000) (citing Saunders v. Edenton Ob/Gyn Ctr., 352 N.C. 136, 140, 530 S.E.2d 62, 65 (2000)).\nThe Commission\u2019s finding that plaintiff\u2019s right knee injury was causally related to the compensable left knee injury is based upon plaintiff\u2019s own self-diagnosis and the expert medical testimony of Dr. Schutte. \u201c[W]here the exact nature and probable genesis of a particular type of injury involves complicated medical questions far removed from the ordinary experience and knowledge of laymen, only an expert can give competent opinion evidence as to the cause of the injury.\u201d Click v. Freight Carriers, 300 N.C. 164, 167, 265 S.E.2d 389, 391 (1980). Because plaintiff\u2019s testimony is not adequate to establish medical causation, we focus solely upon Dr. Schutte\u2019s expert medical testimony. Such medical expert testimony is not sufficiently reliable to qualify as competent evidence on issues of medical causation when it is based merely upon speculation and conjecture. Holley, 357 N.C. at 232, 581 S.E.2d at 753 (quoting Young, 353 N.C. at 230, 538 S.E.2d at 915).\nPlaintiff contends that Dr. Schutte\u2019s medical opinion was that her compensable left knee injury caused her right knee injury. This contention is not supported by Dr. Schutte\u2019s testimony. Dr. Schutte testified as follows:\nQ. Let me ask you about this statement in the May 16th medical note. It says: \u201cShe started shifting her weight over the past month to the right knee following the injections.\u201d And she had problems with her left knee. Is shifting weight over something called over compensation?\nQ. Is that a possible cause for an aggravation of any underlying diagnoses in the right knee to make them symptomatic?\nA. Yes, it\u2019s possible.\nQ. If I were to ask you that Miss Nale had the injury that we had talked about back in July of 2005. That if she did not have the right knee problems at that time, and did not have any right knee problems until about the time in March of 2007 or April of 2007 when she came to you for the injection of the left knee. And then reported to you in May 2007 that she had what sounded to be mechanical symptoms of the popping, the clicking and pain getting up from the knee from shifting her weight over to that knee.\nIf I were to ask you to assume that those subjective complaints of hers were credible and valid, do you have an opinion to a reasonable degree of medical certainty, again not to an absolute degree, but a reasonable degree as to whether there was a contribution in her right knee symptoms from her left knee injury.\nA. I have no doubt that her right knee was working harder than her left knee, given that she has arthritis in her left knee and was favoring that knee. The finding, at the time that we scoped her knee was she had a plica, which is a band of scar tissue, which in her case, is another condition to wear away the scar tissue. The plica is not something that would form as a result of over activity on that knee, that\u2019s just one of those things that happens.\nQ. And let me separate the other one. I think I just asked you this a second ago. If you assumed that she had not had right knee problems until the time frame that she had the left knee injection, and she started shifting her weight over, according to your medical records, and assuming that the Industrial Commission would say that history was credible, is that the likely cause, at least by the history, that Miss Nale gave to you that of her right knee symptom?\nA. I thought the history I had was that she had a twisting injury the Friday before I saw her.\n(emphasis added).\n\u201cAlthough expert testimony as to the possible cause of a medical condition is admissible if helpful to the jury, it is insufficient to prove causation, particularly when there is additional evidence or testimony showing the expert\u2019s opinion to be a guess or mere speculation.\u201d Holley, 357 N.C. at. 233, 581 S.E.2d at 753 (citations and quotations omitted). Dr. Schutte\u2019s answers-to the above questions indicate that he believed plaintiff\u2019s right knee injury stemmed from a twisting injury and a plica. He stated the plica was not something that would develop due to over-activity. Plaintiff cites this Court to the portion of Dr. Schutte\u2019s testimony that: \u201cno doubt that her right knee was working harder than her left knee\u201d to support her assertion that her right knee injury stemmed from her favoring her left knee. However, when asked if this over-compensation could be an aggravating factor underlying the symptoms of plaintiff\u2019s right knee, Dr. Schutte only said it was possible. \u201cDoctors are trained not to rule out medical possibilities no matter how remote; however, mere possibility has never been legally competent to prove causation.\u201d Id. at 234, 581 S.E.2d at 754 (citing Young, 353 N.C. at 233, 538 S.E.2d at 916). Dr. Schutte never provides a causal link, rising to a level above mere possibility, between plaintiff\u2019s compensable left knee injury and her right knee injury. \u201cAlthough medical certainty is not required, an expert\u2019s \u2018speculation\u2019 is insufficient to establish causation.\u201d Id. (quoting Young, 353 N.C. at 233, 538 S.E.2d at 916).\nPlaintiff had the burden of establishing that the right knee injury was the direct and natural result of the compensable left knee injury. This had to be shown through expert medical testimony. Cannon, 171 N.C. App. at 262, 614 S.E.2d at 445 (citations omitted). Plaintiff failed to meet this burden. Dr. Schutte\u2019s testimony was that the plica was not the result of over-activity of the right knee arising from the left knee injury. We are not persuaded by plaintiff\u2019s attempt to lift one sentence out of Dr. Schutte\u2019s answer, while ignoring the balance of his answer to the same question.\nWe also reject the Commission\u2019s attempt to establish causation based upon plaintiff\u2019s self-diagnosis of the cause of her right knee injury, and the temporal sequence of the two injuries. It is not for the Commission to render its own expert medical opinions. Edmonds v. Fresenius Med. Care, 165 N.C. App. 811, 818-19, 600 S.E.2d 501, 506 (2004) (Steelman, J., dissenting), rev\u2019dper curiam for reasons stated in dissent, 359 N.C. 313, 608 S.E.2d 755 (2005).\nV. Temporary Total Disability\nIn their second argument, defendants contend the Commission erred in awarding plaintiff temporary total disability payments for the period of time between 1 May 2006 and 28 December 2006. We remand this issue to the Commission for further findings of fact.\nDefendants contest findings of fact numbers nineteen and twenty, and argue that these findings do not support Conclusion of Law number six, which states, \u201cPlaintiff was totally disabled because of her injury for the 241 days between May 1, 2006, and December 28, 2006. N.C. Gen. Stat. \u00a7 97-29.\u201d They contend that plaintiff \u201ccannot establish and has failed to satisfy her burden with respect to \u2018disability.\u2019 \u201d We note the record reveals that this period of disability predated any injury to the right knee and is thus solely attributable to the left knee.\nThe Worker\u2019s Compensation Act defines disability as \u201cincapacity because of injury to earn the wages which the employee was receiving at the time of injury in the same or any other employment.\u201d N.C. Gen. Stat. \u00a7 97-2(9) (2007).\nIn order to support a conclusion that plaintiff was disabled, the Commission must find:\n(1) that plaintiff was incapable after his injury of earning the same wages he had earned before his injury in the same employment,\n(2) that.plaintiff was incapable after his injury of earning the same wages he had earned before his injury in any other employment, and\n(3) that this individual\u2019s incapacity to earn was caused by plaintiff\u2019s injury.\nHilliard v. Apex Cabinet Co., 305 N.C. 593; 595, 290 S.E.2d 682, 683 (1982) (citing Watkins v. Motor Lines, 279 N.C. 132, 181 S.E.2d 588 (1971)). Plaintiff bears the burden of proving both the extent and degree of her disability. Brown v. S & N Communications, Inc., 124 N.C. App. 320, 329, 477 S.E.2d 197, 202 (1996) (citing Watson v. Winston-Salem Transit Authority, 92 N.C. App. 473, 475, 374 S.E.2d 483, 485 (1988)).\nAs to plaintiffs incapacity to earn wages, the Commission found:\n15. Plaintiff worked during all periods in which her doctors allowed her to work. Both before and after May 1, 2006, Plaintiff continued to have the medical restrictions given to her by Dr. Smith and Dr. Bensen. She continued to work at Defendant-Employer even though her normal work activities exceeded those restrictions.\n16. On May 1, 2006, Plaintiff voluntarily left Defendant-Employer\u2019s Charlotte location and moved to Charleston, South Carolina, to remarry. After the injury on July 14, 2005, Plaintiff states she began to shift her weight from her left side to her right side because of her left knee pain.\n19. Between May 1, 2006, and December 28, 2006, Plaintiff received unemployment compensation while in South Carolina and looked for other work. She satisfied all of the job search requirements under the law for purposes of receiving unemployment compensation, but did not get hired. Plaintiff was capable of some work between May 1, 2006, and December 28, 2006, and made a reasonable effort to find other work during this period, but without success. On December 28, 2006, Plaintiff returned to work in Charleston, South Carolina.\nDefendants argue that plaintiff has not satisfied the third prong of Hillard because she voluntarily chose to resign her position at Ethan Allen. We decline to discuss this argument because findings of fact sixteen and nineteen are in conflict as a matter of law.\nIf plaintiff voluntarily quit her employment with Ethan Allen in North Carolina, she could not be drawing unemployment from the State of North Carolina. N.C. Gen. Stat. \u00a7 96-14 (2007). Further, she could not have quit her job in North Carolina on 1 May 2006 and immediately have begun collecting unemployment compensation from the State of South Carolina.\nThe record on this matter is not totally clear. It appears that plaintiff left the employ of Ethan Allen in North Carolina in February of 2006 and went to work at an Ethan Allen store in Charleston, South Carolina. Plaintiff lost this job when the store was bought out, and she was not retained as an employee. She then began drawing unemployment in South Carolina based upon her employment in Charleston on 1 May 2006.\nIt is not. the role of the appellate courts to make findings of fact. Bowen v. ABF Freight Sys., Inc., 179 N.C. App. 323, 330-31, 633 S.E.2d 854, 859 (2006). It is the role of the Industrial Commission to make findings of fact. Id. at 327, 633 S.E.2d at 857 (citations omitted). Based upon the findings made by the Commission, we are unable to decide the appellant\u2019s second argument. This case is remanded to the Commission for additional findings of fact resolving the conflicts in the Commission\u2019s Opinion and Award. Specifically, the Commission shall determine the date plaintiff left the employ of Ethan Allen in North Carolina, where and when she worked in South Carolina, and the reason for her termination in South Carolina.\nDefendants have failed to argue their remaining assignments of error in their brief, and they are thus deemed abandoned pursuant to Rule 28(b)(6) of the Rules of Appellate Procedure. N.C.R. App. P. 28(b)(6).\nREVERSED IN PART, REMANDED FOR ADDITIONAL FINDINGS OF FACT IN PART.\nJudges HUNTER, ROBERT C. and GEER concur.\n. This statute has been amended by 2009 N.C. Sess.
