Abstract
An endoprosthetic knee comprising a tibial plate having a smooth proximal face and a distal face, an anchor on the distal face for anchoring the plate to the proximal end of a resected tibia, and at least one bollard on the proximal face of the tibial plate. At least one unicompartmental meniscal component has a substantially flat distal face for glidable seating on the tibial plate and a dished proximal face for receiving an articulating condylar surface of a femoral component anchorable to the distal end of a resected femur. A flexible mooring moors the meniscal component to the bollard on the tibial plate to permit limited gliding movement of the meniscal component upon the tibial plate.
