摘要： A hinged knee prosthesis includes a femoral component with a tibiofemoral articular surface that is distinct from the patellofemoral articulating surface. Fully congruent tibiofemoral articulation is provided for virtually all flexion angles. Additionally, the bearing is capable of at least limited axial rotation relative to the tibial component but is restrained against dislocation. Accordingly, dislocation is much less likely even n those situations where collateral ligaments are insufficient.

摘要： The tibial component of a prosthetic ankle joint including a tibial component, a talar component, and an intermediate sliding plastic bearing, with the tibial component including a depending peripheral wall that surrounds and is spaced from the plastic bearing and is intended to reduce rubbing of the plastic bearing against tissue which would produce wear particles that lead to the formation of bone cysts. The depending peripheral wall of the tibial component is intended to reduce such possible abrasions by at least partially shielding the plastic bearing from the surrounding tissue.
