Facts

• The Worker, employed as a housekeeper by Hyatt Regency Tamaya, experienced severe knee pain after work, leading to a total knee replacement. The Worker had preexisting osteoarthritis and a medial meniscus tear, which were aggravated by her job activities. Despite her condition worsening after work, the Employer denied her claims for disability and medical costs, attributing her condition to natural progression or an incident outside of work.

Procedural History

• [Not applicable or not found]

Parties' Submissions

• Worker-Appellant: Argued that the evidence did not support the finding of an accident occurring after work, the IME applied an incorrect causation standard, and her expert provided sufficient evidence of aggravation.
• Employer/Insurer-Appellees: Contended that the Worker's injury was caused by a preexisting condition or an event outside of work, and that the Worker's condition was the result of natural progression rather than workplace activities.

Legal Issues

• Whether substantial evidence supported the WCJ’s finding that the Worker suffered an accident outside of work.
• Whether the IME applied an incorrect causation standard in evaluating the Worker's condition.
• Whether the Worker's employment activities aggravated her preexisting osteoarthritis.

Disposition

• The Court of Appeals reversed the WCJ's decision and remanded the case for further determination of benefits, costs, and fees the Worker may be entitled to.

Reasons

• The Court found that:
  Substantial evidence did not support the WCJ’s finding of an accident occurring outside of work, as the Worker's increase in pain at Walgreens did not prove a discrete accident occurred there (paras 7-11).
  The IME applied an incorrect legal standard for determining aggravation, requiring a specific traumatic event or physical tissue change, which contradicts New Mexico law stating that increased pain is sufficient for aggravation (paras 17-21).
  The Worker's expert testimony established a causal connection between her work-related activities and the aggravation of her preexisting condition, sufficient to meet the burden of proof for a compensable injury under New Mexico law (paras 22-24).
  The Court concluded that the WCJ's findings were not supported by substantial evidence, specifically regarding the cause of the Worker's knee pain and the applicability of the correct legal standard for aggravation (paras 25-26).
