LCL injury; Knee injury - lateral collateral ligament (LCL)Definition Return to top
LCL injury is a stretch, partial tear, or complete tear of the lateral collateral ligament (LCL) of the knee. (The term "lateral" means the ligament is on the outside of the knee.)Considerations Return to top
A lateral collateral ligament test may reveal a looseness in the ligament. This involves bending the knee to 25 degrees and placing pressure on the inside surface of the knee.Causes Return to top
The lateral collateral ligament (LCL) extends from the top-outside surface of the fibula (the bone on the outside of the lower leg) to the bottom-outside surface of the femur (the thigh bone). The ligament stabilizes the knee on the outside of the joint.Symptoms Return to top
First Aid Return to top
Initial treatment of an LCL injury includes ice to the area, elevation of the joint (above the level of the heart), nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibruprofen or aspirin, and limited physical activity until the pain and swelling subside.
Immobilization for a period of time is generally necessary for pain relief and healing. Physical therapy is usually helpful to regain knee strength and flexibility.
Surgery for isolated LCL injuries is not generally necessary. However, this ligament is commonly injured during significant trauma, including knee dislocations. When injuries to the LCL occur with other ligament injuries, repair is necessary to prevent future instability of the knee.
Call immediately for emergency medical assistance if Return to top
Call your health care provider if you injure your knee and symptoms of LCL injury occur.Prevention Return to top
Use proper technique when exercising or playing sports. Many cases may not be preventable. Update Date: 8/3/2004 Updated by: Kevin B.
