Abstract
in English, Chinese

Objective: To summarize the application and research progress of robotic-arm in total knee arthroplasty (TKA).

Methods: Relevant literature at home and abroad was extensively reviewed to analyze the advantages and disadvantages of robotic-arm assisted TKA (RATKA).

Results: Accurate reconstruction of lower extremity alignment and rotation alignment, accurate osteotomy and implant prosthesis in TKA are very important to improve the effectiveness and prolong the life of the prosthesis. Traditional TKA deviations occur in key links such as osteotomy due to operator's operation. RATKA solves the above problems to a certain extent and can assist accurate osteotomy and implant prosthesis, and protect the soft tissues around the knee joint. Patients' satisfaction after RATKA is high, and the operator's learning curve is shorter, which improves the efficiency of the operation. But it also has disadvantages such as prolonged operation time, increased complications and medical costs.

Conclusion: Preliminary clinical application studies have shown that RATKA has satisfactory effectiveness, but its definite advantages compared with traditional TKA need to be confirmed by a large number of randomized controlled trials and long-term follow-up.

目的: 总结手术机器人在人工全膝关节置换术（total knee arthroplasty，TKA）中的应用及研究进展。.

方法: 查阅国内外相关文献，分析手术机器人辅助 TKA（robotic-arm assisted TKA，RATKA）的优势及不足。.

结果: TKA 术中准确重建下肢力线和旋转对线、精确截骨和植入假体对于提高疗效及延长假体寿命至关重要。传统 TKA 由于术者操作因素存在截骨偏差等问题，而 RATKA 在一定程度上解决了上述问题，能辅助精确截骨及植入假体、能更好地保护膝关节周围软组织。RATKA 术后患者满意度高，且术者学习曲线较短、提高了手术效率，但也存在手术耗时延长、并发症增加、医疗成本提高等不足。.

结论: 初步临床应用研究显示 RATKA 疗效满意，但与传统 TKA 相比其确切优势尚待大样本随机对照研究和长期随访来验证。.
