Background
Aaron Underwood, a worker employed by ACNR Resources, Inc., twisted his right knee at work in July 2024. He sought workers’ compensation benefits, including authorization for a total knee replacement recommended by his treating physician, Dr. Adam Edward Klein. Underwood argued that the workplace incident constituted a discrete new compensable injury, emphasizing that his knee had been fully functional at the time of the incident and that the injury necessitated surgery beyond anything previously required.
Underwood had a significant preexisting history with his right knee, including a prior partial knee replacement and prior treatment for osteoarthritis and a right medial tibial plateau fracture — diagnoses that predated the July 2024 incident. The claim administrator rejected the claim in August 2024, finding that the workplace event aggravated a preexisting condition rather than causing a discrete new injury. Both the West Virginia Workers’ Compensation Board of Review and the Intermediate Court of Appeals (ICA) affirmed that determination.
Underwood appealed to the Supreme Court of Appeals of West Virginia, arguing that the need for a total knee replacement demonstrated a qualitative change in his condition sufficient to constitute a new compensable injury under the standard established in Gill v. City of Charleston, 236 W. Va. 737, 783 S.E.2d 857 (2016).
The Court’s Holding
The Supreme Court of Appeals summarily affirmed the ICA’s decision without oral argument, finding no reversible error in the lower tribunals’ conclusions. The court applied a deferential standard to the Board of Review’s factual findings, reversing only if those findings were clearly wrong, while reviewing legal questions de novo under Duff v. Kanawha County Commission, 250 W. Va. 510, 905 S.E.2d 528 (2024).
The court agreed with the employer’s position that the preponderance of the evidence supported treating the July 2024 incident as an aggravation of Underwood’s longstanding preexisting right knee condition, not a discrete new injury. Because the diagnoses listed on the physician’s injury report — osteoarthritis and right medial tibial plateau fracture — predated the workplace event, the claim was properly rejected as non-compensable under Gill.
Key Takeaways
- Under Gill v. City of Charleston, aggravation of a noncompensable preexisting condition is not itself compensable; only a resulting discrete new injury may qualify for workers’ compensation benefits.
- The need for more extensive surgery (e.g., a total knee replacement following a prior partial replacement) does not automatically establish a discrete new injury if the underlying diagnoses predate the workplace incident.
- The Board of Review’s factual findings receive deference and will not be disturbed unless clearly wrong; the claimant bears the burden of demonstrating that a new injury, rather than an aggravation, occurred.
Why It Matters
This decision reinforces the line West Virginia courts draw between compensable discrete new injuries and non-compensable aggravations of preexisting conditions — a distinction that frequently determines the outcome of workers’ compensation claims for employees with prior medical histories. Employers and insurers can point to this ruling as confirmation that preexisting diagnostic findings, even where a claimant undergoes more significant post-injury treatment, can defeat compensability under the Gill framework.
For injured workers and their counsel, the case underscores the importance of establishing — through medical evidence — that a workplace incident produced a pathological change distinct from any preexisting condition, rather than merely worsening an existing one. Claims involving prior surgeries or chronic conditions will face heightened scrutiny at every level of the West Virginia workers’ compensation system.
