Abstract

The utility model relates to a novel knee joint femoral condyle prosthesis, which comprises an inner side condyle, an outer side condyle and a patellar surface. The utility model provides a thighbone condyle prosthesis, its outside condyle rear height and the high inequality in inboard condyle rear, outside condyle rear height is higher, reduces the unsettled of outside condyle when making the high bucking of knee joint to improve the stability of knee joint motion.

Description

Novel knee joint thighbone condyle prosthesis

Technical Field

The utility model relates to the field of medical equipment, in particular to a femoral condyle prosthesis for artificial knee joint replacement.

Background

The artificial knee joint replacement is one of effective means for treating knee joint bone fracture diseases, and the artificial joint prosthesis is implanted into a human body through surgical operation to replace the diseased joint part, so that the aims of relieving joint pain and recovering joint function are fulfilled. The femoral condyle plays an important role as a component of the artificial knee joint prosthesis, and the stability of the motion of the femoral condyle directly influences the life quality of a patient. When the knee joint is in high flexion, the lateral condyle is easily separated from the tibial pad to be suspended, so that the knee joint is unstable in motion, the height of the rear part of the lateral condyle of the existing femoral condyle prosthesis is equal to that of the rear part of the medial condyle, and the problem is not well solved.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve above-mentioned problem, provide a novel knee joint thighbone condyle prosthesis, can reduce the unsettled of outside condyle when the high bucking of knee joint to improve the stability of knee joint motion.

In order to achieve the purpose, the utility model adopts the following design scheme:

the utility model provides a novel knee joint thighbone condyle prosthesis comprises inboard condyle, outside condyle and patellar surface, its characterized in that: the posterior height of the lateral condyle is not equal to the posterior height of the medial condyle, and the posterior height of the lateral condyle is higher.

Preferably, the lateral postcondylar height is 0.5mm-8mm higher than the medial postcondylar height.

The utility model has the advantages that:

the utility model discloses a thighbone condyle prosthesis, outside condyle rear height is high than inboard condyle rear height, makes the knee joint when high bucking motion, reduces the separation of outside condyle and tibia pad, increases the contact time of outside condyle and tibia pad to knee joint motion's stability has been improved.

In order to make the technical solution of the present invention more clearly understood, the following description will be made in detail with reference to the accompanying drawings and examples. It is obvious that the embodiments described herein are only some of the embodiments of the present invention, which are used for explaining the present invention, and are not used for limiting the present invention.

Drawings

Fig. 1 is a schematic structural view of the novel knee joint femoral condyle prosthesis of the present invention.

Fig. 2 is another schematic structural diagram of the novel knee joint femoral condyle prosthesis of the present invention.

In the figure: 1. a medial condyle; 2. the lateral condyle; 3. a patellar surface; 11 posterior medial condyle; 21. posterior to the lateral condyle.

Detailed Description

The first embodiment is as follows: as shown in figure 1, the novel knee joint femoral condyle prosthesis comprises a medial condyle 1, a lateral condyle 2 and a patellar surface 3, wherein the medial condyle posterior 11 is not equal to the lateral condyle posterior 21 in height, and the lateral condyle posterior 21 is 1mm higher than the medial condyle posterior 11.

Example two: as shown in figure 2, the novel knee joint femoral condyle prosthesis comprises a medial condyle 1, a lateral condyle 2 and a patellar surface 3, wherein the medial condyle posterior 11 is not equal to the lateral condyle posterior 21 in height, and the lateral condyle posterior 21 is higher than the medial condyle posterior 11 by 3mm in height.

Claims
