An important cause of adhesive stiffness in joints is muscle inactivity. Long-term braking of the affected limb results in slow venous and lymphatic stagnation, tissue edema, and the formation of adhesions between the joint capsule folds and synovial reflexes and the muscles by exuded plasma fibrin, as well as tissue changes in the soft tissues surrounding the joint. The basis for the release of intra-articular adhesions is surgery, and the decision to release the middle femoral muscle is based on the passive range of motion of the knee joint after delivery. For the management of the middle femoral muscle, an oblique cut of the skin of the middle muscle can be performed, which is beneficial for the recovery of muscle strength of the quadriceps muscle after surgery. Joint function training is to prevent joint contracture and promote joint function recovery centripetal manipulation with joint function training, which is more conducive to joint function recovery.
