The average LEFS change score for patients with hip, leg, or ankle injuries treated during the observation period will be reported. Additionally, a risk-adjusted LEFS change difference score will be calculated by subtracting the predicted LEFS change score from the average LEFS change score for each patient, then average the adjusted scores for each physical therapist or physical therapy group. The risk adjustment will be calculated using generalized linear modelling adjusting for: baseline LEFS score, baseline pain score, age, sex, smoking, comorbidities, payer, and symptom duration (time from surgery or injury to baseline physical therapy visit). These measures will serve as a physical or occupational therapy performance measure at the eligible physical or occupational therapist or physical or occupational therapy group level. Rate 1: Average LEFS Change Score, Rate 2: Risk-adjusted Average LEFS Change Score.
