Abstract
OBJECTIVE: To systematically summarize the application and research progress of robot-assisted total knee arthroplasty (TKA) in the treatment of valgus knee from the perspective of precision medicine in recent years, so as to provide a reference for the clinical treatment of valgus knee. METHODS: Relevant domestic and foreign literature, including clinical studies and evidence-based evaluations regarding robot-assisted TKA versus conventional TKA for valgus knee, was reviewed. A systematic analysis was performed focusing on technical advantages, efficacy differences and existing controversies. RESULTS: Conventional TKA is limited by surgeons' experiences, leading to insufficient accuracy in alignment correction, great challenges in soft tissue balance, and postoperative residual deformity. Robot-assisted TKA is significantly superior to conventional approaches in terms of alignment correction accuracy, joint function improvement, and reduction of postoperative complication rates, with confirmed short-term effectiveness. Nevertheless, controversies remain concerning the limitations of robot applicability, prolonged operation time and uncertain long-term effectiveness. CONCLUSION: Robot-assisted TKA provides a precision-oriented therapeutic option for valgus knee with remarkable short-term effectiveness. Further large-sample studies with long-term follow-up are still required to verify its efficacy and facilitate its clinical popularization.
