Approximately 80,000 to 250,000 anterior cruciate ligament (ACL) injuries occur each year in the United States. Risk factors include high-impact sports activity, high body mass index (BMI), and individual-specific neuromuscular patterns. Research suggests that there is a 4% to 15% chance of recurrent partial or complete ligament tear and a 5% to 24% chance of injury to the opposite limb after surgery. Physical therapy interventions—such as bracing and a combination of non-weight-bearing and weight-bearing exercises—can increase the chances that the patient will return to preinjury activity levels and prevent a recurrence.
