Ligament rupture can occur in people who like to exercise when they overdo it or exercise improperly. Treatment for a torn ligament can be conservative or surgical, depending on the location of the torn ligament or the extent of the torn ligament. For the more common cases of partial strain of the lateral collateral ligament of the ankle or the lateral collateral ligament of the knee, conservative treatment may be given to those who are older or less active. The affected limb is immobilized in a cast or brace for 4-6 weeks, and the cast or brace can be removed for functional exercise after 4-6 weeks. After the medial collateral ligament of the knee, medial collateral ligament of the ankle, or the stronger ligaments such as the Achilles tendon are completely stretched, surgery is usually required to repair them. The surgery is mainly to pull the ruptured ligament back to its original stop, and to restore the continuity of the ligament by fixing it with accurate alignment and sutures. If the strength of the ligament cannot be restored to its original level after the expected repair, ligament reconstruction surgery is required, and the material used for reconstruction can be chosen from your own tendon or artificial ligament.
