“…With standard physical therapy treatments (range of motion treatments, soft tissue manipulation, moist heat), the mean flexion contracture decreased to 5°, 2°, 1°, and 1°at 3, 6, 12, and 24 months postoperatively, respectively. Logerstedt and Sennett [16] described the use of a drop-out cast, which held the knee in extension without the application of elastic bands. The cast was applied by the patient for 6 to 8 hours every night in conjunction with stretching, exercise, and knee mobilization, to treat four patients who had a mean age of 20 years and who had recalcitrant knee flexion contractures after anterior curciate ligament reconstruction.…”
