Comparison of the clinical results of mobilebearing and fixed-bearing prostheses used for total knee arthroplasty in patients with osteoarthritis
Abstract
Background: The aim of this study was to investigate the changes in pain, function, stiffness and complications over time in patients with osteoarthritis who underwent total knee arthroplasty (TKA) with fixed or mobile-bearing.
Methods: This study is a prospective cohort type study performed with gonarthrosis patients that underwent TKA. Western Ontario and McMaster Universities Arthritis Index (WOMAC) and American Knee Society Score (AKSS) were used for clinical evaluation (pain, function and stiffness). The post-treatment measurements of patients were performed at the one-year follow-up.
Results: The study group consisted of 63 patients with a mean age of 63.57 ± 8.13 years. WOMAC and AKSS scores of the patients improved significantly in both groups over time. WOMAC pain score was found to be lower in the fixed-bearing group in the postoperative first year. The WOMAC function score was lower in the mobile-bearing group at 6 months and 1 year postoperatively. The AKSS pain score was significantly lower in the mobile-bearing group in the preoperative period and in the fixed-bearing group at postoperative third month. The AKSS function score was significantly lower in the fixed-bearing group in the third and sixth postoperative months. In the postoperative period, no significant difference was found between groups in terms of radiolucent area size, infection and complication development.
Conclusions: Significant clinical improvements were observed in both types of prostheses during the follow-up of patients. While there were differences in clinical outcomes between the groups during the follow-up period, the two groups were similar in terms of complications.
