In the early stages of joint capsule injury, cold compresses and external immobilization are needed, followed by further conservative treatment such as medication or surgery, depending on the extent of the injury. In the early stage of joint capsule injury, cold compresses and ice packs are needed as soon as possible to make the ruptured blood vessels contract and minimize bleeding and joint swelling. For mild joint capsule injuries such as joint capsule strain, short-term braking such as external immobilization of the affected joint is needed, and after the acute phase, local electric grilling and acupuncture can be carried out, together with oral anti-inflammatory and pain-relieving drugs such as diclofenac and ibuprofen. For severe joint capsule injuries, such as joint capsule tear, arthroscopic surgery is usually needed to repair and fix the damaged area, and rehabilitation training of joint function should be started two to three weeks after surgery to avoid muscle degeneration. Therefore, it is recommended to have further examination and choose appropriate treatment measures under the guidance of the doctor to restore the normal function of the joint capsule. The above medications should be used under the guidance of a doctor to avoid self-medication.
