We systematically reviewed the radiological outcomes of studies comparing robotic-assisted (RA-THA) and manual total hip arthroplasty (mTHA).
The PubMed, Embase, and Cochrane databases were queried from 1994-2021 for articles comparing radiographic outcomes between RA-THA and mTHA cohorts. A meta-analysis was conducted whenever sufficient data was present for common outcomes.
Our analysis included 20 articles reporting on 4140 patients (RA-THA: n = 1228; mTHA: n = 2912). No differences were demonstrated for acetabular inclination or anteversion. However, RA-THA demonstrated higher rates of cup orientation within the Lewinnek and Callanan safe zones, improved femoral stem alignment, and lower global offset difference (GOD) and limb length discrepancy (all p-values <0.05). Superior femoral canal fill and combined offset were seen among RA-THA patients.
Our review found that the use of RA-THA yields superior radiographic outcomes compared to mTHA counterparts. This information can inform healthcare systems considering investing in and implementing these technologies.
我们系统地回顾了比较机器人辅助（RA-THA）和手动全髋关节置换术（mTHA）的研究的影像学结果。
从 1994 年至 2021 年，我们在 PubMed、Embase 和 Cochrane 数据库中检索了比较 RA-THA 和 mTHA 队列之间影像学结果的文章。只要存在足够的常见结果数据，就进行了荟萃分析。
我们的分析包括 20 篇报告了 4140 名患者的文章（RA-THA：n=1228；mTHA：n=2912）。髋臼倾斜或前倾角没有差异。然而，RA-THA 显示出更高的杯方位在 Lewinnek 和 Callanan 安全区域内的比率，改善了股骨柄的对准，以及更低的总偏移差（GOD）和肢体长度差异（所有 p 值<0.05）。RA-THA 患者中还观察到更好的股骨干道填充和联合偏移。
我们的综述发现，与 mTHA 相比，使用 RA-THA 可获得更好的影像学结果。这些信息可以为考虑投资和实施这些技术的医疗保健系统提供参考。
