Abstract

The objective of this longitudinal study was to determine the predictive value of pre-treatment patient characteristics on joint-specific and generic health status in knee osteoarthritis (OA) patients after 4 weeks of physical therapy. The Portuguese Knee injury and Osteoarthritis Outcome Score (KOOS) and Medical Outcomes Study - 36 item Short Form (SF-36) questionnaires, and a form for the other patient characteristics (gender, age, body mass index, profession, professional situation, educational level, marital status, duration of knee OA, involved knee and walking aids) were self-administered to 202 subjects with symptomatic knee OA (145 females, 57 males; age: 67.3 ± 8.9 years). The questionnaires were administered before and after treatment. The form was administered before treatment. Multiple stepwise regressions analyses revealed that pre-treatment patient characteristics explained 37.2% to 44.8% of the variance in post-treatment KOOS subscales scores, and 25.8% to 55.1% of the variance in post-treatment SF-36 subscales scores. The strongest predictor of post-treatment health status across all dimensions was the pre-treatment score of each dimension. The other patient characteristics added relatively little predictive value either for knee-specific or generic health status obtained after 4 weeks of physical therapy for knee OA.
