Abstract
The authors present a case of bilateral stress fracture of the femoral shaft 15 years after total knee arthroplasty. Considerable femoral bowing deformity and varus malposition of the femoral and tibial components after total knee arthroplasty may produce abnormal stresses and lead to stress fracture of the distal femur in the region of greatest curvature.
摘要
作者报告了1例全膝关节置换术后15年发生股骨干双侧应力性骨折的病例。全膝关节置换术后，股骨出现明显的弓形畸形以及股骨和胫骨假体的内翻畸形，可能会产生异常应力，导致股骨远端最大弯曲区域发生应力性骨折。
