TKA postoperative joint instability correction trousers

Abstract

The invention provides TKA postoperative flexion instability correction trousers. The trousers comprise elastic trousers that feet can step on, shank fixing belts, thigh fixing belts, a waist fixing belt, elastic fastening belts between shanks and feet, elastic fastening belts between the shanks and thighs (one inside the leg and the outer outside the leg), elastic fastening belts between the thighs and the waist, and knee pad reinforcing belts; the elastic trousers that feet can step on are used as a base body, the fixing belts are all connected to the trousers body through trouser loops, theend parts of the fixing belts are provided with lantern rings and nylon locking buckles, and the two ends of the buckles can be fixed to form a sleeve; and two ends of each elastic fastening belt areprovided with nylon locking buckles which are arranged between the two fixing belts in a connection mode, and the fastening belts can adjust the tightness by means of belt holes on the fixing belts,change the pulling force between the fixing belts, and maintain the normal physiological gap between the femur and the tibia of the knee joint. The correction trousers with a body frame can improve the knee joint gap, can correct the situations of unstable flexion and over-extension of the knee joint when the knee joint moves, and are simple and convenient to operate, 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
