Revision Of Partial To Total Knee Arthroplasty Using Robotic Assistance

Description

This episode of AI Talks with Bone & Joint discusses the March 2026 paper "Revision of partial to total knee arthroplasty using robotic assistance" by B. Ingelaere and F. Hardeman. Hosted by Simon and Amy, the conversation explains the background of knee osteoarthritis and why partial knee arthroplasty, while beneficial for isolated compartment disease, has a higher revision rate than total knee arthroplasty. The study examined 23 patients who underwent robotic-assisted conversion from partial to total knee arthroplasty using the ROSA Knee System and the Persona Total Knee System, with anatomical landmark registration performed before explantation to help restore joint line and alignment. The hosts highlight the study’s key findings, including improved Oxford Knee Scores from 17.2 to 40.0 at 12 months and reduced pain scores from 6.7 to 1.6, along with successful robotic registration in all cases and only one requiring extra intervention due to cystic bone loss. They also note that radiological accuracy was high, with minimal alignment error in most measures, and conclude that robotic assistance appears feasible, reproducible, and promising for improving outcomes in complex revision knee surgery.
