Supracondylar and distal femoral fractures involving total knee arthroplasties present a relatively new and challenging problem. The alignment of the total knee components prior to and subsequent to the fracture, as well as the patients' range of motion, symptoms, and level of function following their treatment, were investigated in 14 cases. Ten of the patients had nonoperative treatment. Four had had an operative procedure. Osteoporosis, notching of the femur, and revision arthroplasty were identified as predisposing factors with femoral fractures. The results of treatment depended primarily on reduction of varus deformity and/or posterior displacement of the femoral component. Nonoperative treatment was most successful in this regard.
涉及全膝关节置换术的股骨髁上和股骨远端骨折是一个相对较新且具有挑战性的问题。我们对14例患者骨折前后全膝关节组件的对线情况，以及治疗后患者的活动范围、症状和功能水平进行了研究。其中10例患者接受了非手术治疗，4例接受了手术治疗。骨质疏松、股骨切迹和翻修关节成形术被确定为股骨骨折的诱发因素。治疗结果主要取决于股骨组件内翻畸形和/或后移位的复位情况。在这方面，非手术治疗最为成功。
