Postoperative knee adhesions can be given conservative treatment and surgical treatment. 1. Conservative treatment: Acupuncture, massage, ultrasound and low-frequency pulsed magnetic therapy can be given to improve the blood circulation of the knee joint, which can help to relieve inflammation, promote the absorption of fluid, loosen the adhesion of the soft tissues, reduce the pain, and improve the mobility of the joints, and at the same time can be used for functional exercises. 2. Surgery: Minimally invasive interventional surgery can be given to treat severe symptoms, which can quickly and accurately solve the adhesion problem. After the diagnosis of postoperative knee adhesion, it is necessary to regulate the exercise and accept the regular treatment in time to avoid causing adverse effects.
