Abstract
A three-component prosthetic joint comprising a first bone-attachable component having a planar articular surface and a second bone-attachable component having an arcuate articular surface and a substantially congruent bearing component held therebetween, avoids extrusion of the bearing component without reduction in the efficacy of the prosthesis as an implantable joint when the substantially congruent planar articular surfaces of the bearing component and the first component are in free-floating contact and the substantially congruent arcuate articular surfaces of the second component and the bearing component are unicentric and include a system of interlockable flanged grooves which prevent both separation of the arcuate surfaces when interlocked and also medial-lateral movement therebetween.
