What to know about lateral collateral ligament injuries

The LCL is a connective tissue band referred to as a ligament. It travels down the outside of the knee and links the femur (thigh bone) to the fibula (lower leg bone).

The medial collateral ligament is a comparable ligament found on the inside of the knee (MCL). Collateral ligaments work in tandem to support the knee. They regulate the side-to-side movement of the knee and assist in preventing the joint from performing abnormal or strange motions. The LCL is critical for knee stabilization. Activities that place a strain on this ligament, such as bending, twisting, or rapidly changing directions, may result in various degrees of injury. While most injuries occur as a result of severe collisions in sports, the LCL may also be injured as a result of a vehicle accident, fall, or other incident that hits the region.

Anything that exerts stress on the LCL puts the individual at risk of sustaining an LCL injury. Injuries may be more prone to develop when a force or impact forces the knee in an unnatural direction. With sufficient power, this may result in damage to the knee’s supporting tissues, including the collateral ligaments. The LCL runs along the outside of the knee and contributes to joint stabilization. Impacts or abrupt twists from sports or other forms of stress may injure the ligament to different degrees. Treatment and recovery periods may vary significantly depending on the kind of damage and the number of affected structures. Minor injuries may not result in long-term complications. Working with a physical therapist may assist in strengthening the region and reestablishing range of motion as quickly as possible after an accident.
