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.
