A prosthetic knee having as its component parts a femoral implant, a tibial implant, and a meniscal plate disposed between the implants. Knee flexion and extension is permitted by compoundly curved condyle surfaces of the femoral implant, which resemble corresponding surfaces of a natural knee, and correspondingly shaped convex bearing surfaces in the meniscal plate. All other motions of the prosthetic knee take place at the interface between the meniscal plate and tibial implant. This interface is defined by a continuous, concave, spherically shaped surface in the upwardly facing plateau of the tibial implant and a corresponding, continuous, convex spherical surface of the meniscal plate. The components are biased into mutual engagement along the cooperating concave and convex surfaces by the natural ligaments which surround the prosthetic knee. The continuous biased engagement of the cooperating convex and concave surfaces of the prosthetic knee assure its stability.
