Abstract:
1. A joint prosthesis, comprising: a femoral component having first condylar articular surface, a second condylar articular surface, and an intercondylar recess interposed therebetween; a tibial component having a bone engaging portion and defining a connection bore; a meniscal component having a stem positioned within said connection bore of said tibial component so as to rotatably mount said meniscal component to said tibial component, and further having a first bearing surface and a second bearing surface spaced apart from each other so as to define a channel; and a stabilizing post slidably mounted within said channel of said meniscal component, said post projecting into said intercondylar recess when said first condylar articular surface and said second condylar articular surface are respectively positioned in contact with said first bearing surface and said second bearing surface, wherein no relative movement occurs between said stem and said first bearing surface and said second bearing surface during sliding of said stabilizing post within said channel of said meniscal component.
