The purposes of this study were to compare operated and nonoperated knees after anterior cruciate ligament reconstruction using the semitendinosus tendon and a polypropylene ligament augmentation device, and to determine the interrelationships among strength, knee stability, and current activity levels. Isokinetic tests for knee flexion (prone position) and extension (sitting position) strength during concentric-eccentric muscle action cycles were completed at 60 and 180 deg/sec angular… CONTINUE READING
