Problems solved by technology

However, the traditional tibial tray prosthesis needs to re-drill the column hole and the keel slot when the model is changed, and because the columns and keel positions of the adjacent tibial tray prosthesis are relatively close, when re-drilling the colum

Abstract

The invention relates to a knee joint system, a tibial prosthesis, a tibial tray prosthesis series and a tibial tray prosthesis group. The tibial tray prosthesis group comprises at least two tibial tray prostheses of different models, wherein each tibial tray prosthesis is provided with a stand column connected with a tibia and a keel; each tibial tray prosthesis is further provided with a first reference surface and a second reference surface; the second reference surface is intersected with the first reference surface; and when the first reference surfaces of the tibial tray prostheses of different models are aligned and the second reference surfaces are aligned, the stand columns of the tibial tray prostheses of different models are overlapped and the keels are overlapped. According tothe tibial tray prosthesis group, the fixing stability of the tibial tray prostheses is improved and the loosening probability of the tibial tray prostheses is reduced. Meanwhile, stand column holes and keel 13 grooves do not need to be formed again so that the operation efficiency is also improved, the operation time is shortened and the infection probability of patients is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a knee joint system, a tibial prosthesis, a tibial tray prosthesis series and a tibial tray prosthesis group. Background technique [0002] Unicompartmental replacement uses a minimally invasive incision while preserving the anterior and posterior cruciate ligaments of the knee joint. It has the advantages of less trauma, faster recovery, and better postoperative physiological activity. Therefore, unicompartmental replacement is widely used in unicompartmental surgery. In the treatment of osteoarthritis. The unicompartmental knee prosthesis used in unicompartmental replacement includes the femoral condyle prosthesis for replacing the diseased bone tissue of the distal femur, the tibial tray prosthesis for replacing the diseased bone tissue of the proximal tibia, and the replacement of the meniscus to achieve Tibial padding to reduce friction and wear. [0003] During a ...
