Unicondylar knee joint prosthesis capable of preventing looseness and working method thereof

Abstract

The invention provides a unicondylar knee joint prosthesis capable of preventing looseness. The unicondylar knee joint prosthesis comprises a femoral prosthesis, a platform pad and a platform support which are sequentially arranged from top to bottom, the platform pad is used for being in rotary sliding fit with the femoral prosthesis, the platform support is used for supporting the platform pad, a fixing column A and a fixing column B are arranged above the femoral prosthesis, and a magnetic head and a sensor module which are matched with each other are arranged in the femoral prosthesis and the platform pad respectively. The unicondylar knee joint prosthesis is reasonable in design, simple in structure and convenient to use, loosening of the prosthesis can be known in time, and further treatment is performed in advance to prolong the service life of the prosthesis.

Description

technical field

[0001] The invention relates to a unicompartmental knee joint prosthesis capable of preventing loosening and its application method. Background technique

[0002] Artificial single knee arthroplasty is a kind of artificial joint replacement surgery, which refers to the removal of the articular surface that cannot be repaired by the human body, and the replacement of damaged joints with artificial joint parts, to correct the line of limbs, eliminate knee joint pain, and maintain joint stability It is a treatment method to restore the function of the knee joint. A unicompartmental knee prosthesis is a surgical implant used to replace the knee joint and is used in unicompartmental knee replacement surgery. Compared with total knee replacement, unicompartmental knee arthroplasty can significantly reduce intraoperative bleeding and postoperative recovery time. Because it retains the anterior and posterior cross ligaments of the human body, it maintains the stabil...
