An orthopaedic knee component for implanting within a proximal tibia includes a tibial tray with a proximal tibial plateau and a projection extending generally orthogonal to the tibial plateau. The tibial tray also includes a distally extending stem. A bearing is coupled with the tibial plateau and has an articular bearing surface for engagement with a femoral component. The bearing is rotationally movable between a first rotational limit and a second rotational limit about an axis extending generally orthogonal to the tibial plateau. The bearing has a backing surface engaging the tibial plateau which is sized and shaped such that the backing surface is substantially entirely supported by the tibial plateau at any position during rotational movement between the first rotation limit and the second rotational limit.

Orthopaedic instrumentation used for preparing a distal end of a femur during an orthopaedic revision surgery includes a cutting guide block with a medial side, a lateral side and an anterior cutting guide surface. The medial side and the lateral side each have a notch therein. An anterior flange is removably attached to the cutting guide block and positioned adjacent to the anterior cutting guide surface. The anterior flange includes a pair of arms which are respectively disposed within the medial side notch and the lateral side notch.
