Radiographs were obtained at the initial visit and the posterior 45° flexed weightbearing view was used to evaluate for osteoarthritis.34 Patients attended physical therapy and were given a rehabilitation program that included exercises to restore full knee extension equal to the opposite normal knee first, followed by exercises to restore normal knee flexion. Light strengthening exercises were prescribed as needed when knee range of motion was restored, and the exercises included the stationary bike, single leg press, and single leg extension.
