摘要
An orthopaedic system includes an insert defining an anterior-posterior centerline and including: a medial half on one side of the centerline and defining a medial shape, the medial half having a medial articular surface defining a medial dwell region; and a lateral half on an opposite side of the centerline and defining a lateral shape that differs from the medial shape, the lateral half having a lateral articular surface. A femoral component includes a medial condylar portion bearing on the medial articular surface and a lateral condylar portion bearing on the lateral articular surface. The insert is configured to substantially limit medial anterior-posterior translation on the femoral component and define a pivot axis that extends through the medial dwell region. The insert is configured such that rotation of the lateral articular surface follows an arcuate path about the pivot axis.
