Anterior Cruciate Ligament (ACL) Injuries
- ACL ruptures are common athletic injuries leading to knee anterior and lateral rotatory instability.
- ACL is one of the four main stabilizing ligaments of the knee.
- ACL prevents forward movement of the tibia in relation to the femur and controls rotational movement of the tibia under the femur.
- ACL is essential for control in pivoting movements.
- The most common contact injury is when force is applied to the lateral side of the knee that results in a large valgus movement.
- The most common non contact injury occurs through a rotational mechanism in which the tibia is externally rotated.
- The patient often describes an audible ‘pop’, ‘crack’ or feeling of ‘giveway’.
- Generalized knee pain
- Feeling of instability preventing return to sport
- Difficulty in weight bearing
- Pain, swelling
- Loss of ROM
- Discomfort while walking
- Physical examination
- Conservative or surgical depending on the tear.
