An isolated polyethylene exchange (IPE) is a revision procedure with mixed results in the literature, typically indicated for well-aligned total knee arthroplasties with instability. Surgeons often rely on subjective feedback and experience to determine whether an IPE or a more involved revision procedure is necessary. The technique of robotic-assisted IPE offers the potential for more precise decision-making in revision knee arthroplasty. Robotic systems can provide intraoperative data that may help identify ideal candidates for IPE and guide the selection of the appropriate PE component to address instability. Future studies comparing robotic-assisted IPE with traditional methods are needed to investigate patient-reported outcomes and functional results.
孤立性聚乙烯交换（IPE）是一种翻修手术，在文献中的结果不一，通常适用于对线良好但存在不稳定的全膝关节置换术。外科医生常常依靠主观反馈和经验来确定是否需要进行IPE或更复杂的翻修手术。机器人辅助IPE技术为膝关节置换翻修手术中更精确的决策提供了可能。机器人系统可以提供术中数据，这可能有助于识别IPE的理想候选者，并指导选择合适的聚乙烯组件来解决不稳定问题。未来需要开展将机器人辅助IPE与传统方法进行比较的研究，以调查患者报告的结局和功能结果。
