Description
Objectives: In the literature, there is a debate regarding the performance of bilateral total knee arthroplasty in one surgery. The purpose of the study was to analyze the clinical and radiological results after bilateral knee arthroplasty with the CORI robotic system.
Methods: 50 patients underwent bilateral total knee arthroplasty (1 surgery) using the CORI robotic system. The range 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 33 women (66%) and 17 men (34%), with a mean age of 72.5 years (range 47-82). Patients were mobilized within 10.5 hours (range 8-13 hours) after surgery and the mean hospital stay was 3 days (range 2-4 days). There was a significant improvement in pain and functional status immediately postoperatively, while the restoration of the mechanical axis was complete. Only 2 patients (4%) were transfused. Patients' overall quality of life was significantly better for both SF-12 parameters. All patients returned immediately to their homes without the need for further physical therapy.
Conclusions: The CORI robotic system can provide excellent functional and clinical results even when performing bilateral total knee arthroplasty in 1 operating session. Specialized experience is required, in order to apply all the advantages of robotics and achieve the optimal result while minimizing the risk of complications.
