Ten years of knee tendon adhesion with muscle atrophy is considered to be a long time activity restriction caused by disuse atrophy, suggesting surgical release and functional exercise. 1. Surgical treatment: knee tendon adhesion for ten years with muscle atrophy for a long time, the knee joint is difficult to flexion and extension activities. It is recommended to perform arthroscopic surgery to release the tendon, and then fix it with plaster or brace in the early stage after surgery to perform isometric contraction of the muscle. Non-steroidal anti-inflammatory and analgesic drugs (diclofenac sodium tablets, flurbiprofen ester cream) and anti-swelling drugs (diosmin tablets) should be applied at the same time. Generally, the swelling can be eliminated 1 week after the operation, remove the plaster or brace, and carry out functional exercise. 2. Functional exercise: carry out knee flexion and extension activities and strength training, and at the same time give physical therapy (infrared rays, short microwave), acupuncture, massage therapy, to prevent the tendon from re-adhesion. At the same time, nutrition should be strengthened, generally after about 1 year of functional exercise of the knee joint, the atrophied muscles can be gradually recovered. Tendon adhesion accompanied by muscle atrophy, it is recommended to actively consult a regular hospital, under the guidance of physicians, do not blindly use drugs.
