Tibial prosthesis with independent medial and lateral baseplates
摘要
A tibial prosthesis with independent medial and lateral baseplates. The baseplates can be coupled together for simultaneous implantation using an implantation apparatus. A high-molecular weight polyethylene upper part with articulating surface can then be attached both to the baseplates and to the tibia. The resulting prosthesis can conform to the stabil condition of the tibia without rocking in the baseplates. Bony ingrowth from the tibial head into special surfaces of the baseplates securely attaches the baseplates to the tibial head and the possibility of diminished fixation is reduced.
