Abstract:
The Lacey Rotating-Hinge (Wright Medical, Arlington, TN) total knee is a constrained device for reconstruction of knees without collateral ligaments or to replace resected bone. Problems have been described with hinged total knees such as stem fracture, particulate synovitis, and stem loosening. A different mode of failure is described here. Two case histories are provided in which similar fractures occurred in the lateral condyle of Lacey Rotating-Hinge total knees.
