title: Fracture of polyethylene tibial component in a total knee replacement. A case report.
abstract: Aseptic loosening is the most common mode of failure for total knee replacements. Component breakage is rare, usually attributable to errors of design or manufacture. A case is presented in which rotational malplacement of the femoral component resulted in accelerated wear and eventual fracture of the polyethylene tibial component.
