Adhesions in the knee need to be treated with medication, manipulation, surgery and rehabilitation exercises according to the specific cause of the disease. 1. Not accompanied by knee joint injury: if the patient’s knee adhesion is caused by knee joint synovitis and other lesions that are not accompanied by internal injuries, the treatment is often based on manipulation to loosen the adhesive tissue. If the patient feels obvious pain during the process of manipulation, anti-inflammatory painkillers such as Celecoxib can be taken to relieve pain. Surgery should be considered if the adhesions are severe and difficult to release by manipulation. The use of related drugs should be careful to follow the doctor’s instructions. 2. Accompanied by intra-articular knee injury. If the adhesions are caused by internal knee lesions such as meniscal injuries, the preferred treatment is arthroscopic repair of the damaged tissues. Whether it is after manipulation or arthroscopic surgery, patients should insist on rehabilitation exercises such as knee flexion and extension exercises to strengthen the flexibility of the knee joint under the guidance of professionals. It is recommended that the patient should consult a doctor and follow the doctor’s instructions.
