Facts about Lateral collateral ligament
- 08
Posterolateral corner injuries involving the lateral collateral ligament account for approximately 16 percent of acute knee ligament injuries in professional sports populations.
- 07
In full knee extension, the lateral collateral ligament becomes the primary restraint to varus stress, but this function diminishes significantly as the knee flexes beyond 30 degrees.
- 06
Athletes with lateral collateral ligament injuries often retain functional stability because this ligament's primary role in restraining varus stress becomes less critical when the knee is flexed during most daily activities.
- 05
Isolated lateral collateral ligament injuries occur in only 2 to 3 percent of all knee sprains because this ligament rarely tears without concurrent damage to other knee structures.
- 04
Rotational knee injuries commonly injure the lateral collateral ligament because it provides primary restraint to varus stress and external tibial rotation, particularly when the knee is extended.
- 03
Inversion ankle sprains frequently damage the lateral collateral ligament because its superficial location and lack of capsular reinforcement make it more vulnerable to tensile forces than the thicker medial counterpart.
- 02
The fibular collateral ligament, as the lateral collateral ligament is also known, attaches proximally to the lateral epicondyle of the femur and distally to the fibular head, remaining separate from the knee joint capsule unlike its medial counterpart.
- 01
Approximately 2 millimeters thick, the lateral collateral ligament of the knee is considerably thinner than the medial collateral ligament at 4 to 5 millimeters.
