Abstract

Purpose: Robot-assisted total hip arthroplasty (R-THA) is being adopted progressively because of its potential to improve implant positioning and restore hip biomechanics more accurately than conventional techniques. However, whether these technical advantages translate into meaningful clinical benefits remains uncertain. This systematic review compared robot-assisted and conventional THA regarding implant positioning, restoration of hip biomechanics, functional outcomes, and complications.

Materials and methods: A systematic review was performed according to the PRISMA guidelines. PubMed and Scopus were searched for comparative studies published between 2015 and September 2025 evaluating robot-assisted versus conventional THA. After applying predefined eligibility criteria, 13 studies were included. Methodological quality was assessed using the MINORS and RoB 2 tools, and findings were synthesized qualitatively.

Results: Robot-assisted THA was consistently associated with greater accuracy of acetabular component placement within established safe zones and more precise restoration of limb length. Functional outcomes were inconsistent across studies, with no clear evidence of superior patient-reported outcomes or overall clinical benefit. Several studies reported lower rates of dislocation and reoperation following robot-assisted THA, although differences in overall complication rates were less consistent.

Conclusions: Robot-assisted THA improves the accuracy of implant positioning and better reproduces the preoperative surgical plan than conventional THA. However, these technical advantages have not translated into superior functional outcomes in the short to medium term. Longer-term studies are needed to determine their impact on implant survival.

机器人辅助全髋关节置换术：精确度的提高是否意味着更好的临床结果？系统回顾。

目的：机器人辅助全髋关节置换术（R-THA）正逐渐被采用，因为它有可能改善植入物的定位，并比传统技术更准确地恢复髋关节的生物力学。然而，这些技术优势是否转化为有意义的临床效益仍不确定。本系统综述比较了机器人辅助和传统THA在植入物定位、髋关节生物力学恢复、功能结果和并发症方面的差异。材料和方法：根据PRISMA指南进行系统评价。PubMed和Scopus检索了2015年至2025年9月期间发表的比较研究，评估机器人辅助与传统THA。在应用预定的资格标准后，纳入了13项研究。使用minor和RoB 2工具评估方法学质量，并对研究结果进行定性综合。结果：机器人辅助THA始终与髋臼假体在既定安全区域内放置的准确性和更精确的肢体长度恢复有关。各研究的功能结果不一致，没有明确的证据表明患者报告的结果更好或总体临床获益。一些研究报道了机器人辅助THA后脱位和再手术的发生率较低，尽管总体并发症发生率的差异不太一致。结论：与传统THA相比，机器人辅助THA提高了种植体定位的准确性，更好地再现了术前手术计划。然而，这些技术优势并没有在中短期内转化为优越的功能结果。需要长期研究来确定它们对种植体存活的影响。

期刊介绍： International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters. Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
