Author(s): Kaan Celebi, PT, DPT; Airelle Hunter-Giordano, PT, DPT, Board-Certified Orthopaedic Clinical Specialist, Board-Certified Sports Physical Therapy Clinical Specialist
Anterior cruciate ligament (ACL) tears are the most common ligamentous injuries that occur in the knee. (1) People who have an ACL injury usually are involved in high-level cutting and pivoting sports, and many are under 25 years of age. (2) The ACL injury likely occurs when the loading of the ACL exceeds its limits: when a quadriceps femoris muscle force is applied with knee internal rotation, a valgus load is combined with knee internal rotation, or there are excessive valgus loads during rapid deceleration. (3) (Figs. 1, 2).
