The treatment of joint capsule injury occurs, including the following aspects: First, mild joint capsule injury, i.e. joint capsule strain, there will be mild edema, pain and limited joint movement, which requires short-term braking of the joint, local cold compresses, with ultrashort wave therapy, and also oral anti-swelling and pain-relieving drugs, such as Cao Wu Jia Su tablets. After the above comprehensive conservative treatment, the mild joint capsule injury can be gradually repaired. Secondly, for severe joint capsule injuries, such as joint capsule tears, arthroscopic surgery is usually considered to repair the damaged part of the joint capsule, which can improve the stability of the joint, protect the structures within the joint and avoid recurrence of joint capsule injuries. After surgery, functional exercises for the shoulder joint and other joints are needed to avoid atrophy of the muscles around the joint, thus strengthening the stability of the joint.
