270 So. 3d 37
Miss. Ct. App.2018Background
- On July 25, 2014, Gregory Graham injured his left knee at work delivering milk; knee treatment included PT and surgery and he was ultimately restricted from lifting over 40 pounds.
- Graham fell at home in March 2015 when his left leg "gave way," and immediately developed neck/back pain; he saw treating physicians thereafter.
- Employer Prairie Farms admitted the knee injury but disputed that Graham’s subsequent back injury was compensable under workers’ compensation; parties stipulated to Graham’s pre-injury average weekly wage and that temporary and some permanent benefits had been paid.
- Employer obtained an Employer Medical Evaluation (Dr. Rahul Vohra), who assigned a 10% left-knee impairment, agreed MMI, and concluded the back complaints were not related to the knee injury; Dr. Robert Kimber (spine specialist) concluded the back was aggravated by the knee/leg problems.
- The Administrative Judge found a 50% industrial loss of use of the left lower extremity and that Graham sustained a compensable back injury causally related to the knee injury; the full Commission adopted the AJ’s findings and Prairie Farms appealed.
Issues
| Issue | Plaintiff's Argument (Graham) | Defendant's Argument (Prairie Farms) | Held |
|---|---|---|---|
| Whether Graham suffered a 50% industrial loss of use of the left lower extremity | Knee injury prevented continuation in prior job; post-injury wage capacity far below pre-injury wage | Medical impairment ratings (Dr. Salloum/Dr. Vohra) showed only 10% functional impairment; vocational prospects existed at $8–$11/hr | Affirmed: substantial evidence supported 50% industrial loss (industrial loss ≠ functional impairment; focuses on wage-earning capacity) |
| Whether Graham’s back injury was compensable as arising from the work-related knee injury | Fall caused by knee buckling aggravated preexisting back condition; specialists and medical notes support causal link | Back condition preexisted, prior surgery and degenerative disease show independent cause; expert (Dr. Vohra) said back not related to knee | Affirmed: Commission credited Graham and Dr. Kimber; substantial credible evidence supported compensability as aggravation of preexisting condition |
