Conversion of a failed unicompartmental knee arthroplasty (UKA) to total knee arthroplasty (TKA) is challenged by asymmetric bone loss necessitating advanced fixation strategies and alignment considerations. Robotic-assisted TKA is an increasingly utilized tool to augment preoperative surgical planning, improve intraoperative execution, and optimize patient outcomes. However, the use of robotic-assisted TKA in conversion UKA is not well described in the literature. We present the authors' preferred surgical technique of conversion UKA utilizing robotic assistance with a haptically guided robotic system and present a case example of a patient managed with this technique.
单髁膝关节置换术（UKA）失败后转换为全膝关节置换术（TKA）面临着不对称骨丢失的挑战，这需要先进的固定策略和对线考虑。机器人辅助TKA是一种越来越多地用于增强术前手术规划、改善术中操作并优化患者预后的工具。然而，文献中对机器人辅助TKA在UKA转换中的应用描述并不充分。我们介绍了作者使用触觉引导机器人系统进行机器人辅助UKA转换的首选手术技术，并展示了一例采用该技术治疗的患者案例。
