2026 AAHKS Annual Meeting: Robotic-Assisted vs. Manual Revision Total Knee Arthroplasty: A Matched Cohort Study

186 patients undergoing aseptic revision total knee arthroplasty (rTKA) were retrospectively evaluated after receiving conventional manual rTKA (n=112) or robotic-assisted revision TKA (rarTKA) (n=74), with 74 matched pairs included in the comparative analysis. The primary outcome of interest was postoperative knee range of motion (ROM). Secondary outcomes included posterior condylar offset (PCO) restoration, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR), implant construct characteristics, perioperative outcomes, and re-revision-free survivorship. Outcomes were assessed at 1 and 2 years, with ROM evaluated at a minimum of 6 months and a mean follow-up of 2.4 years. Overall, the results revealed that rarTKA was associated with significantly greater ROM and PCO restoration compared to manual rTKA, while patient-reported outcomes and re-revision-free survivorship were similar. These findings suggested that robotic assistance may provide modest functional and radiographic advantages without improving short-term implant survivorship.
