Although robotic assistance has demonstrated efficacy in primary TKA, its application in partial revision procedures remains poorly understood. This study presents a case of robotic\u2010assisted partial rTKA\u2014specifically, isolated tibial component revision using the retained femoral component as a registration reference\u2014and provides a comprehensive review of the current literature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>A 66\u2010year\u2010old male presented with progressive knee pain 8\u2009years after left TKA. Imaging revealed a well\u2010fixed femoral component but isolated aseptic loosening with posterior tilting of the tibial component. Given the stability of the femoral component, a robotic\u2010assisted partial revision targeting only the tibial component was performed. The robotic system was registered intraoperatively using the well\u2010fixed retained femoral component as the primary reference, enabling accurate spatial orientation despite the altered tibial anatomy. A critical prerequisite for this procedure was implant compatibility between the retained Triathlon femoral component and the planned Triathlon TS revision system. After removal of the loose tibial tray and debridement, robotic\u2010arm guidance was used for precise tibial osteotomy with a 10\u2009mm augment. Postoperative imaging confirmed optimal component positioning. The patient achieved 0\u00b0\u2013130\u00b0 range of motion within 2\u2009weeks, with favorable short\u2010term clinical and radiological outcomes at 1\u2009year follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case demonstrates the technical feasibility of robotic\u2010assisted partial TKA revision, with favorable short\u2010term clinical and radiological outcomes at 1\u2009year follow\u2010up. The technique enabled precise osteotomy, balanced gap restoration, and preservation of the well\u2010fixed femoral component. While these preliminary results are encouraging, larger studies with longer follow\u2010up are needed to establish comparative effectiveness and generalizability.<\/jats:p>\n
