[citation needed] Deep to the ligament are the tendon of the popliteus, and the inferior lateral genicular vessels and nerve.

With the knee in flexion, the radius of curvatures of the condyles is decreased and the origin and insertions of the ligaments are brought closer together which make them lax.

The LCL can also be injured by a noncontact injury, such as a hyperextension stress, again causing varus force across the knee.

Ice, electrical stimulation and elevation are all methods to reduce the pain and swelling felt in the initial stages after the injury takes place.

Physical therapy focuses on regaining full range-of-motion, such as biking, stretching and careful applications of pressure on the joint.

Continued pain, swelling and instability to the joint after this time period may require surgical repair or reconstruction to the ligament.
