A kind of trousers for correcting joint instability after tka operation

Abstract

The present invention provides a buckling instability correcting trousers after TKA, which comprises: elastic trousers that can be stepped on, calf fixing belt, thigh fixing belt, waist fixing belt, elastic fastening belt between calf and foot, and elastic fastening belt between calf and thigh. The elastic fastening belt (one on the inside and one on the outside of the leg), the elastic fastening belt between the thigh and the waist, and the knee pad reinforcement belt; among them, the elastic pants that can be stepped on are used as the base, and the fixing belts are connected with the trousers through the loops. There are loops and velcro at the end of the belt, and the two ends can be fixed to form a sleeve; the two ends of the elastic fastening belt are equipped with velcro, which is connected between the two fixing belts. The holes are used to adjust the tightness, change the tension between the fixing belts, and maintain the normal physiological gap between the femur and tibia of the knee joint. The orthopedic trousers with body frame of the present invention can improve the knee joint gap, and can correct the unstable flexion and hyperextension of the knee joint when the knee joint moves, and the operation is simple, convenient and practical.

Description

technical field [0001] The invention relates to a knee joint instability correction trousers, in particular to a correction trousers for improving joint instability after knee joint replacement. Background technique [0002] Total knee arthroplasty (TKA) is one of many successful surgical procedures that can improve knee function and achieve good prosthetic survival rates. A good surgical effect depends on the proper balance of osteotomy and soft tissue, and in most cases the surgeon needs to complete the balance between osteotomy, soft tissue and lining during the operation. The ideal goal of this procedure is to obtain a rectangular gap in extension or 90° flexion after osteotomy and soft tissue balance. Although several methods can be used to loosen soft tissue, any method depends on the experience of the surgeon, especially for patients with severe varus, the balance of soft tissue is very difficult, and excessive soft tissue loosening will affect the surgical effect. ...

AI Technical Summary

Problems solved by technology

In patients with knee flexion contracture, the medial collateral ligament is excessively released, and the posterior joint capsule is not well released, which will lead to instability during knee flexion (30°-60° or even 90°)
