UNLABELLED
We report a case of fracture of a titanium nitride-coated femoral component 3 years after primary total knee arthroplasty (TKA). The fracture was at the medial condylar area just posterior to the medial peg of the femoral component. The backside of the broken medial condylar portion of the femoral component was devoid of cement. Debonding of the component is a possible cause of the stress fracture. To our knowledge, this is the first case report of the fracture of the femoral component manufactured from titanium alloy.
LEVEL OF EVIDENCE
IV.
未标注
我们报告一例初次全膝关节置换术（TKA）3年后氮化钛涂层股骨部件骨折的病例。骨折位于股骨部件内侧栓钉后方的内侧髁区域。股骨部件断裂的内侧髁部分背面没有骨水泥。部件脱粘可能是应力性骨折的原因。据我们所知，这是首例关于钛合金制造的股骨部件骨折的病例报告。
证据级别
