After ligament injury, the acute phase management mainly involves protection, elevation, avoiding the use of non-steroidal anti-inflammatory and pain-relieving drugs, compression, and patient education, and, of course, appropriate use of cold compresses. In the subacute phase, when there is no pain, some load can be added appropriately, maintaining an optimistic attitude, engaging in aerobic exercise to improve local blood circulation, and early activity should focus on practice as well as exercise in muscle strength and proprioception. Of course, in severe cases where the ligament injury is completely ruptured, affecting stability, consideration must be given to ligament repair or reconstruction. But for acute cases, there is definitely no need for cortisone injections. For chronic ligament injuries, with long-term chronic pain around the joint, conservative treatment and other methods are ineffective, local injections may be considered. However, it is advisable not to inject the injured ligament itself but rather the synovial sheath or other soft tissues surrounding the ligament, as this can reduce the damage of the injection drugs to the ligament. (Use of specific medications should be under the guidance of a physician.)
