Stiffness after elbow surgery is not a stiff tendon, but a stiff joint, which may be a complication of poor postoperative recovery, or may be caused by myofasciitis, and the cause of the problem should be identified in a timely manner. Pathological changes such as adhesion, capsular contracture and ligament contracture in the soft tissues around the elbow joint after surgery may limit joint movement and lead to joint stiffness. After joint stiffness occurs, patients need to carry out functional exercises at an early stage, and if their own functional exercises are not in place, they can seek the help of rehabilitation doctors to carry out rehabilitation training for them. If the patient does not pay attention to rest after the operation, excessive exercise or overexertion can cause myofasciitis. It is a strain change, it is recommended to improve the patient’s lifestyle, rest at the same time with hot compresses, if necessary, can be prescribed to give non-steroidal anti-inflammatory drugs for symptomatic anti-inflammatory analgesic treatment, such as aspirin and so on. If there is a serious case of postoperative joint stiffness, you should go to the hospital in a timely manner, by the doctor to clarify the cause of the disease, to give targeted treatment, so as not to delay the condition.
