A lateral collateral ligament (LCL) injury occurs when the ligament on the outer side of the knee is damaged, often due to a direct impact to the inside of the knee or a twisting motion. Symptoms include pain, swelling, instability, and difficulty bearing weight on the affected leg. Treatment typically involves initial rest, ice, compression, and elevation (RICE), followed by the use of a knee brace or splint for immobilization. Physical therapy is often recommended to restore strength, stability, and range of motion in the knee. In some cases, surgery may be necessary for severe injuries.
