The lower surface of tibial plateau pad prosthese is provided with the arc buckling groove that the arc holding section with tibial plateau connecting portion adapts in front portion, the elastic card claw matched with the bayonet socket inside arc holding section it is provided with inside arc buckling groove, the lower surface of tibial plateau pad prosthese is provided with Y shape buckling groove at rear portion, Y shape buckling groove front portion adapts to location division, middle part, and Y shape buckling groove rear portion is the up-narrow and down-wide structure adapting to both wings holding section.
Described tibial plateau pad prosthese is PS type tibial plateau pad prosthese.
Described tibial plateau pad prosthese is PS+ type tibial plateau pad prosthese.
Described tibial plateau pad prosthese is CR type tibial plateau pad prosthese.
Described tibial plateau pad prosthese is AS type tibial plateau pad prosthese.
The invention has the beneficial effects as follows:
1. tibial plateau prosthese and tibial plateau pad prosthese coordinate clamping by the Y shape holding section and the Y shape buckling groove that coordinate clamping, rear portion of anterior arc holding section and arc buckling groove, use simple and easy, fix respond well.
2. the lower surface of the tibial plateau pad prosthese of difference in functionality all adopts the structure in the application, it is possible to achieve the arbitrary load of the tibial plateau pad prosthese of difference in functionality, versatility is stronger.
