Mar 03,2023

According to the used part of the prosthetic leg knee prosthesis material, it can be divided into unicompartmental prosthesis (single-compartmental prosthesis), double-compartmental prosthesis excluding patellofemoral joint replacement, and total joint prosthesis (three-compartmental prosthesis).

Composition and classification of prosthetic leg knee prosthesis material
A prosthetic leg knee prosthesis material consists of three parts:
1. Femoral Prosthesis: Surface replacement of the end of the femur. The femoral prosthesis is composed of metal alloys.
2. Patella prosthesis: replaces the inner surface of the patella that rubs against the femur. The patella prosthesis consists of plastic with a metal alloy backplate.
3. Tibial prosthesis: It can be a single or two-piece design. The one-piece design consists of plastic, and the two-piece design consists of a metal tray attached to the bone and a plastic sheet. Plastic spacers provide a smooth surface on which the femur moves. Plastic spacers are usually attached to the tibial tray.

1. According to the used part of the prosthetic leg knee prosthesis material, it can be divided into unicompartmental prosthesis (single-compartmental prosthesis), double-compartmental prosthesis excluding patellofemoral joint replacement, and total joint prosthesis (three-compartmental prosthesis).
2. According to the fixation method of prosthetic leg knee prosthesis material, it can also be divided into bone cement fixed prosthesis and non-cement fixed prosthesis.
3. According to the degree of mechanical restriction provided in the prosthesis design, it can be divided into non-restrictive prosthesis, partially restrictive prosthesis, highly restrictive prosthesis and fully restrictive prosthesis (hinged prosthesis).
