Description

Rehabilitation device with limited knee joint Technical Field The invention relates to the field of knee rehabilitation devices, in particular to a knee joint limited rehabilitation device. Background The main reasons for limited knee joint movement include 1, synovitis, critical swelling and dropsy, 2, trauma, acute injury of knee joint structure, bleeding and swelling of injury structure, pain, limited joint movement, 3, meniscus tearing or intra-articular free body, possibly resulting in joint interlocking, 4, joint stiffness, usually formed by intra-articular scar after joint operation, limited movement, 5, joint deformity, found in osteoarthritis or rheumatoid arthritis later stage, joint degeneration, deformity and the like, the limited knee joint can cause 1, pain of a patient, 2, limit muscle to exert maximum muscle force-thigh four weakness, 3, cause abnormal walking mode or gait, 4, aggravate symptoms and joint degeneration of patellofemoral joint, and the limited knee joint needs rehabilitation treatment. The method for knee joint limited treatment mainly comprises two steps, namely, conservative treatment, namely, the knee joint limited treatment is more effective by actively performing knee joint bending and stretching exercise through hot compress, physiotherapy, massage and massage, and the knee joint peripheral muscles, tendons, ligaments and the like, and the knee joint limited treatment is restored, and secondly, surgical treatment, namely, 1, arthroscopic minimally invasive surgery, namely, if the knee joint limited in movement occurs, X-ray films, three-dimensional CT and nuclear magnetic resonance are required to be shot, and whether the cause is meniscus injury or hyperplasia osteophyte is determined, and regardless of the cause, surgical treatment, including arthroscopic minimally invasive surgery, is required to repair the meniscus and excise hyperplasia osteophyte, and 2, artificial knee joint replacement surgery, namely, if the knee joint limited in movement occurs, artificial knee joint replacement surgery is required to be considered, and then the knee joint limited movement range is restored, and strict rehabilitation training is required to be matched, so that the joint movement range is gradually improved, and conservative treatment is the most method is adopted by patients, and the knee rehabilitation device is required to be matched during treatment.
