In general the Lateral Collateral Ligament (LCL) is injured less often than the ACL; it can be just as painful. For athletes a tear in the LCL is generally the result of being hit on the inside of the knee, such as during a tackle in football. Falls while skiing also cause LCL tears. Patients frequently report a feeling that the knee has locked, or that they feel a general sense of knee instability. Complete ruptures of the LCL, will generally require Arthroscopic Surgery so that Dr. Nadel can repair the torn ligament, with the goal of getting you back into your sport as quickly as possible.
