Conservative treatment of the knee joint includes the following: first, oral medication, oral cartilage nutrients, such as glucosamine sulfate, glucosamine hydrochloride, and oral anti-inflammatory and analgesic drugs, such as celecoxib, meloxicam, and loxoprofen sodium tablets, as well as oral Chinese medicine, such as tortoise astragalus bone granules and anti-bone growth tablets. Second, physical therapy, for patients with synovitis and joint effusion, microwave physiotherapy or far-infrared physiotherapy can be used to relieve inflammation and eliminate effusion. Third, intra-articular injections can be given to the joint cavity with sodium vitrate, which is good for nourishing the cartilage and protecting the synovial membrane of the knee joint. Fourth, it is important to keep the knee joint warm and avoid overexertion, which can also slow down the progress of the knee joint condition.
