Summary
Robotic total knee arthroplasty with the CORI.
ePosters will be available shortly before Congress
Abstract
Background
Robotic total knee replacement is the new concept in Orthopaedic surgery. Many studies support its use in knee arthroplasty, but still there are different issues to be analyzed.
Objectives
To analyze the robotic technique with CORI and to evaluate the clinical and radiological postoperative results.
Study Design & Methods
220 patients underwent total knee arthroplasty using the CORI robotic system. The 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 129 women (58.6%) and 91 men (41.4%), with a mean age of 71 years (range 59-83). 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). There was a significant improvement in pain and functional status immediately postoperatively, while the restoration of the mechanical axis was complete. No patient was 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
CORI robotic system can provide excellent functional and clinical results even immediately postoperatively. The restoration of the mechanical axis and the kinematics of the knee is absolutely accurate, blood loss is minimal, balancing of the soft tissues is ideal and the postoperative pain is less.
