Introduction: Total knee arthroplasty (TKA) has been the most effective way to reduce pain and improve functional outcome in advanced knee rheumatoid arthritis (RA). It is widely recognized that patients with RA belong to a younger age group and are more prone to revision surgery due to either infection or peri-prosthetic fracture.
Purpose: The aim of this study was to investigate the long-term outcomes in young patients with RA undergoing TKA clinically and radiologically.
Methods and materials: Consecutive 63 patients with 93 cemented total knee arthroplasty (TKA) for RA up to the age of 50 years managed by a single unit between 1989 and 2015 were included in the study. Clinical and radiological outcomes were analysed. Those who underwent revision were analysed in context of intervals from primary surgery, causes and their outcomes.
Results: The mean age of patients at the time of TKAs was 42 years (21-50). Mean follow up was 10 years (1-24). During follow up period, 6 knees (6.5%) needed revision for various reasons. The average time gap between the primary surgery and the revision was 11 years (2-18). Amongst those, 3 knees (50%) were revised for mechanical failure or aseptic loosening and 1 (16.6%) were for periprosthetic infection.
Conclusion: This is one of the largest series of patients with Rheumatoid arthritis with long-term follow-up following TKA. TKA offers a reliable and predictable solution for end stage degeneration following rheumatoid arthritis with good long-term results.
