Survivorship of unicompartmental knee arthroplasty Survivorship Knee Arthroplasty Robot
Conditions
Interventions
A preoperative CT scan was obtained and computer-
aided design (CAD) model was created. Preoperative planning including component size and position and joint anatomy restoration was performed by surgeons. Intraoperatively,
after bone registration,
the ligament balancing curve was generated by applying valgus stress force to knee at 20° intervals from full extension to full flexion. The quantitatively fine tuning of component position was done
Mako calculated the 3D volume of bone resection. This system used tactile feedback and audio signals for controlling high-
speed burr during bone resection. Finally,
Restoris MCK prosthesis (Mako Surgical Corporation,
Fort Lauderdale,
Florida,
USA) using RIO system was implanted according to surgical planning.,The procedure was carried out using we Oxford partial knee microplasty instrumentation and cemented Oxford phase 3 mobile bearing pr
