Abstract
Background
Total knee arthroplasty with the CORI robotic system offers different options to execute the surgical technique
Objectives
The purpose of the study was to compare the bur-all technique with the hybrid-bur with the CORI robotic system and evaluate their advantages and disadvantages.
Study Design & Methods
180 patients underwent total knee arthroplasty using the CORI robotic system. Patients were randomly assigned to 2 groups to have either the bur-all or the hybrid-bur technique. Operative time, extent of pain improvement, accuracy of mechanical axis correction, range of motion, time to return to activities, and any complication were analyzed. Clinical evaluation was performed using the OXFORD KNEE score, pain was assessed with the VAS scale, and quality of life was assessed with the SF-12. Radiological evaluation consisted of plain radiographs.
Results
There were a total of 126 women (70%) and 54 men (30%), with a mean age of 69.5 years (range 52-85). Patients were mobilized within 6.5 hours (range, 5-10 hours) after surgery, and the mean hospital stay was 2 days (range, 1-3 days) for both groups. There was a statistically significant improvement in pain and less blood loss in favor of the bur-all technique, while no differences emerged in terms of functionality and restoration of the mechanical axis. Overall patient quality of life was statistically significantly better for both SF-12 parameters in the first 6 postoperative weeks for the bur-all technique group.
Conclusions
The bur-all technique is the recommended option offered by CORI giving the surgeon the possibility to perceive the essence of robotic surgery. Without being time-consuming, it allows the removal of minimal subchondral bone that has been calculated based on the intraoperative planning providing the optimal functional result for the patient.
