The Articular Surface Replacement (ASR) hip system displayed unexpectedly high failure rates. All patients who underwent revision arthroplasty at our institution were identified. Indications for revision were classified as objectively identifiable or performed for unexplained pain. Clinical outcomes, post ASR revision, were superior in cases where the aetiology for failure was identifiable. Pain and function improved reliably when a targeted objective indication was identified pre-revision, but failed to do so in cases of unexplained pain. Surgeons familiar with the results of this study will be empowered to discuss expectations and realistic outcomes with their patients undergoing complex revision arthroplasty cases.
关节表面置换(ASR)髋关节系统显示出意外的高故障率。确定了在我们机构接受翻修关节成形术的所有患者。翻修的指征分为客观可识别的或因不明原因疼痛而进行的。ASR翻修术后,在故障病因可识别的情况下临床结果更好。如果在翻修前确定了有针对性的客观指征,疼痛和功能会可靠地改善,但在不明原因疼痛的情况下则不然。熟悉这项研究结果的外科医生将有能力与接受复杂翻修关节成形术的患者讨论预期和实际结果。
