Because of the known high complication rate, it is important for both the patient and physician to know as much as possible about the outcome of revision operations for loosened total hip arthroplasties. This study evaluates the changes in subjective ratings and objective kinesiologic measurements from before revision operations through two years after revision operations. The object is to compare these measurements with the measurements of a group of patients with primary replacements. Both groups of patients showed significant improvement in most parameters from before to after surgery. These parameters included walking performance, hip muscle strength, range of motion, forces applied to canes, and the amount of weight borne on the operated limb during quiet standing. Compared to the control group with primary replacements, the group with revision used more assistive devices, had less pain relief, walked slower, had less hip motion, and had more lateral lurch. While results after revision surgery were not as gratifying as those after primary hip replacement, patients requiring revision can still anticipate substantial improvement.
由于已知翻修手术的并发症发生率很高，因此患者和医生尽可能多地了解全髋关节置换术松动翻修手术的结果非常重要。本研究评估了翻修手术前至翻修手术后两年主观评分和客观运动学测量的变化。目的是将这些测量结果与一组初次置换患者的测量结果进行比较。两组患者在大多数参数上从手术前到手术后均有显著改善。这些参数包括步行表现、髋部肌肉力量、活动范围、施加在拐杖上的力以及安静站立时患侧肢体承受的重量。与初次置换的对照组相比，翻修组使用更多辅助装置，疼痛缓解较少，步行较慢，髋部活动较少，且有更多向外侧的蹒跚步态。虽然翻修手术后的结果不如初次髋关节置换手术后的结果那么令人满意，但需要翻修的患者仍然可以预期会有实质性改善。
