Comparison of the clinical results of mobilebearing and fixed-bearing prostheses used for total knee arthroplasty in patients with osteoarthritis

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