Description

A meniscal movement rehabilitation limiter

technical field

The invention relates to a medical device, in particular to a meniscus movement rehabilitation limiter.

Background technique

Patella fractures have a high incidence and are prone to occur in a variety of populations. For example, athletes, physical workers, office workers who have not participated in sports for a long time, etc., can also occur in the buffer process after landing and when the knee joint touches the ground. After the patella fracture occurs, there are generally two treatment methods: 1. After the reduction by traditional Chinese medicine, external fixation is adopted. This method is suitable for external skin infection and other situations where surgical internal fixation is not suitable. The external fixator can have a knee wrap; 2. Surgical Fixation, internal fixation with tension bands, screws or memory alloy patella grasping. The essence of both fixations is to preserve the morphological integrity of the patella and restore its articular surface flatness. The existing treatment methods all require the patient to immobilize. A normal person who stays in bed for 7 days can reduce the thigh muscle dimension by 3%, and joint fixation for more than two weeks can cause muscle atrophy. The ability of the society has a great impact. The effect of external fixation is not ideal. The internal fixation method of surgery consumes a lot of the patient's body and burdens the patient's energy, psychology, body, time and financial resources. After the internal fixation is taken out, there is no good effect. The protective device is prone to secondary injury to the patella. After the patella fractures again, there is no conservative treatment, and surgery is still required.
