Introduction: In patients with Rheumatoid arthritis (RA) who are candidate of total
knee arthroplasty (TKA), we usually face a lot of problem (e.g. soft tissue balance,
bone defect and massive joint deformity). Most authors recommend posterior
stabilizing TKA. We conducted this study to evaluate the safety of using posterior
cruciate retaining (CR) knee arthroplasty in patients with rheumatoid
arthritis.Methods: During the last 10 years, 34 consecutive TKA in patients with RA
were performed. All knees had cemented components with retention of the posterior
cruciate ligament followed in prospective fashion. Assessment was done using knee
score, range of motion, stability and patient’s ability to climb the stairs. Results: The
mean age at surgery was 57 years. The average follow-up was 5.8 years. No
revision was carried out up to now. All of the patients were pain free. More than 91%
of patients were classified excellent as per the knee score. Conclusion: With regards
to knee score, range of motion, stability and patient’s ability to climb the stairs, our
evaluation proves no preference of CR knee arthroplasty in comparison to cruciate
stabilizing type of total knee replacement, which are the treatment of choice; except
the more bone stock remains.
