title: Fracture of the tibial tray of the PCA knee. A case report of early failure caused by improper design.
abstract: Knee prostheses with metal backing of the polyethylene tibial component are nowadays used almost universally. Eight cases of fracture of the metal tray are reported in the literature. We present a case in which the failure could be expected because of improper design of the tibial tray.
