Adhesions after knee surgery can be treated conservatively with functional exercises, and if the result is poor, surgery is recommended to release the adherent tendon. Tendon adhesions after knee surgery can be treated at home with flexion and extension exercises. If the results are not satisfactory, the patient should consult a rehabilitation and physiotherapy department for manipulative joint release and physiotherapy (short microwave). During the exercise period, oral pain medication (celecoxib capsules) and anti-swelling medication (Panlongqi tablets) should be taken. After the exercise, the affected limb should be elevated, and local hot compresses should be applied to reduce the swelling. If the adhesions do not improve with the above treatments, arthroscopic release of the knee is recommended. If the adhesions are severe and the contracture of the knee extensor device is serious, open surgery may be needed to release the adhesions. After surgery, the knee flexion and extension exercises should be strengthened. Postoperative adhesions in the knee joint should be treated under the supervision of a physician.
