Chronic Vs. Acute ACL Tears: Impact of Surgical Timing on Quadriceps Strength

Quadriceps strength plays a large role in returning patients to pre-injury function after an anterior cruciate ligament (ACL) reconstruction. Yet little was known about the impact of surgical timing on strength.

“We wanted to be able to tell patients what to expect in terms of preoperative quadriceps strength and the progression of quadriceps strength postoperatively based on whether they have an acute or chronic ACL tear,” says Rachel Slaven, PT, DPT, a physical therapist at Shelbourne Knee Center.
