Commonly used postoperative rehabilitation treatments for anterior fork include brace protection, physical therapy, muscle strength training, joint mobility training and so on. 1. Brace protection: wearing a brace for protection after surgery is a routine practice in postoperative rehabilitation, and studies have shown that wearing a functional brace after surgery can slow down the progression of osteoarthritis. 2. Physical therapy: Cold therapy, neuromuscular electrical stimulation and other physical therapy can improve muscle inhibition, temporarily reduce joint muscle inhibition before exercise, and can be used as an adjunctive therapy to plyometric training. 3. Plyometrics: Resistance training, which strengthens one’s own muscle strength by adding extra resistance, is a regular part of the postoperative rehabilitation program and can effectively increase muscle strength, reduce pain and improve knee function. It is usually recommended that patients take closed chain training such as cycling and squatting, which can increase muscle strength. 4. Joint mobility training: This is a non-weight-bearing rehabilitation training, the basic principle of which is to make the articular cartilage tissues produce a pump effect through the continuous passive movement of the joints, and provide the synovial membrane with nutrient supply directly to the articular cartilage, in order to reduce the swelling of the joints as well as to promote the repair of the tissues. When the patient carries out rehabilitation training, it must be carried out under the guidance of a professional physician, and when serious discomfort occurs, it is necessary to go to the hospital in time for follow-up.
