The LCL (lateral collateral ligament) is a ligament located on the outside of the knee and contributes to lateral knee stability. It is uncommon for an LCL injury to be in isolation. Typically, an LCL tear is associated with injuries to the ACL, PCL, or a complete knee dislocation. When the LCL is torn, along with the ACL, it is recommended to have surgery approximately 3 weeks after injury. Early reconstruction for an LCL and ACL tear, requires recreating the ACL with a graft through an arthroscopic technique, and open surgery for the LCL. As directed by your physician, a thorough rehabilitation program will begin. Patients are typically able to resume most normal activities within 9 months after surgery.
