To summarize the application and research progress of robotic-arm in total knee arthroplasty (TKA).
Relevant literature at home and abroad was extensively reviewed to analyze the advantages and disadvantages of robotic-arm assisted TKA (RATKA).
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.
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.
总结机器人手臂在全膝关节置换术（TKA）中的应用及研究进展。
广泛查阅国内外相关文献，分析机器人手臂辅助全膝关节置换术（RATKA）的优缺点。
在TKA中准确重建下肢力线和旋转对线、精确截骨及植入假体对于提高手术效果和延长假体使用寿命非常重要。传统TKA因术者操作在截骨等关键环节会出现偏差。RATKA在一定程度上解决了上述问题，可辅助精确截骨和植入假体，并保护膝关节周围软组织。RATKA术后患者满意度高，术者学习曲线较短，提高了手术效率。但它也存在手术时间延长、并发症增多及医疗费用增加等缺点。
初步临床应用研究表明，RATKA疗效满意，但其与传统TKA相比的确切优势尚需大量随机对照试验及长期随访来证实。
