What this Trial Is About
Knee extension loss following an anterior cruciate ligament (ACL) reconstruction is believed to play an important role in quadriceps strength recovery. One of the main goals of the rehabilitation following ACL reconstruction is to restore knee extensor muscle strength. Deficits of more than a five-degree extension range of motion (ROM) could lead to delayed knee functionality and anterior knee pain. However, the effect of knee extension deficits in the early postoperative phase of the ACL reconstruction on knee extensor muscle strength recovery and knee functionality is not yet known. This study aimed to investigate the difference between knee extensor muscle strength recovery and knee functionality in patients with ACL repair who had a knee extension ROM deficit (\>5°) in the early postoperative period and those who did not.
