While total hip arthroplasty (THA) remains effective for improvement of pain and function in patients with osteoarthritis and avascular necrosis, there remain areas of continued pursuit of excellence, including decreasing rates of dislocation, leg length discrepancy, implant loosening, and infection. This review article covers several bearing surfaces and articulations, computer-assisted navigation and robotic technology, and minimally invasive surgical approaches that have sought to improve such outcomes. Perhaps the most significant improvement to THA implant longevity has been the broad adoption of highly cross-linked polyethylene, with low wear rates. Similarly, navigation and robotic technology has proven to more reproducibly achieve intraoperative component positioning, which has demonstrated clinical benefit with decreased risk of dislocation in a number of studies. Given the projected increase in THA over the coming decades, continued investigation of effective incorporation of technology, soft tissue-sparing approaches, and durable implants is imperative to continued pursuit of improved outcomes in THA.
虽然全髋关节置换术(THA)在改善骨关节炎和缺血性坏死患者的疼痛及功能方面仍然有效,但仍有一些领域需要不断追求卓越,包括降低脱位率、腿长差异、植入物松动和感染率。这篇综述文章涵盖了几种承重表面和关节、计算机辅助导航和机器人技术,以及旨在改善这些结果的微创手术方法。对THA植入物使用寿命最显著的改进可能是高交联聚乙烯的广泛采用,其磨损率较低。同样,导航和机器人技术已被证明能更可重复地实现术中部件定位,在多项研究中已证明其临床益处在于降低脱位风险。鉴于预计在未来几十年THA的数量会增加,持续研究如何有效整合技术、软组织保留方法和耐用植入物对于持续追求THA更好的治疗效果至关重要。
