- Abstract:
- Background Severe osteoarthritis of the knee joint is a common disease that causes not only patient suffering but also high costs for the health care system. Although total knee arthroplasty (TKA) has proven to be a highly effective treatment, the rate of complications and resultant patient dissatisfaction are issues that still need to be addressed. Therefore the ATTUNE system was designed to improve the implantation and lead to better clinical results. In the lights of these facts, this study was intended to examine, if the ATTUNE system has a better surgical outcome and leads to higher patient satisfaction than the Press-Fit-Condylar Sigma system. Patients and Methods This study prospectively analyzed 200 patients who had to receive total knee arthroplasty in the Department of Orthopedic Surgery at the Medical University of Graz. The patients in the study were divided into two groups: one of which received the ATTUNE prosthesis system, while the other received the P.F.C. Sigma knee arthroplasty, which has been used as a matter of routine in the last few years. The patients were evaluated preoperatively, then at intervals of seven days, six weeks, and six months after surgery. This evaluation was made using the Visual Analog Scale (VAS), the active Range of Motion (ROM), the Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC), and the Knee Society Score (KSS). Results At no time during the evaluation did the mean VAS, ROM, and KSS scores show marked differences between the two groups. However, patients who had received the ATTUNE total knee arthroplasty had significantly better WOMAC values six weeks after surgery. However, this difference was clinically not relevant. Conclusion The study revealed that there is no significant difference between the two patient groups (and thus methods) in the short-term post-operative period. Therefore we conclude that the ATTUNE system is equally good as the established P.F.C. Sigma system.
