The lateral collateral ligament, or LCL, is the thin band of tissue running along the outside of the knee that connects the thighbone to the fibula.

Like the MCL, the lateral collateral ligament’s main function is to keep the knee stable as it moves through its full arc of motion. The main cause of LCL injuries is direct force to the inside of the knee. This puts pressure on the outside of the knee and causes the ligament to stretch or tear.

The symptoms of a torn or sprained LCL may include swelling or stiffness in the knee, pain or soreness on the outside of the knee, or an overall feeling like the knee is going to give out.

Physical therapy is usually the path to take towards strengthening and regaining range of motion in the knee, but first splinting, icing, and elevating the knee must be done to reduce any swelling that has occurred.

Unfortunately, all of this slows down the healing process. A more effective treatment, like stem cell therapy, is one that may regenerate the ligament and stimulate healing of the original ligament rather than surgically replacing it. Injuries to the LCL aren’t usually treated with surgery. However, the LCL is often injured in conjunction with other ligaments, in which case, surgery is likely recommended.

If you are suffering from a sprained or torn LCL, regenerative medicine may be the answer for you. To talk to a MedRebels physician, click the button below.
