Optimal outcomes of revision femoral arthroplasty include achieving rotational stability of the revision implant, preventing axial migration of the implant to obtain stability, and reproducing normal hip biomechanics. Cemented and proximally porous-coated implants are not well-suited to achieving these goals in the presence of metaphyseal bone defects and poor endosteal cement bonding. Extensively porous-coated implants are more likely to achieve these goals if the selection of the implant is appropriate for each defect encountered and if technical problems can be identified that may arise during canal preparation andcomponent insertion. The selection of curved implants for longer revisions may help avoid complications.
翻修股骨关节成形术的最佳结果包括实现翻修植入物的旋转稳定性、防止植入物轴向移位以获得稳定性以及恢复正常的髋关节生物力学。在存在干骺端骨缺损和骨内膜骨水泥粘结不良的情况下，骨水泥固定和近端多孔涂层植入物不太适合实现这些目标。如果植入物的选择适合所遇到的每种缺损，并且如果能够识别出在髓腔准备和组件插入过程中可能出现的技术问题，那么广泛多孔涂层植入物更有可能实现这些目标。选择弯曲植入物进行更长距离的翻修可能有助于避免并发症。
