Abstract Background Patients with rheumatoid arthritis (RA) undergoing bilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA) are an uncommon population, and their outcomes are also difficult to predict. The purpose of this study was to evaluate whether both bilateral cementless THA and cemented posterior-stabilized TKA (PS-TKA) can provide reliable outcomes for RA patients. Methods We retrospectively reviewed 30 RA patients (60 hips and 60 knees) who underwent both elective bilateral cementless THA and cemented PS-TKA, with a minimum follow-up of 2 years. Clinical, patient-reported, and radiographic data were retrospectively analyzed. Results The mean follow-up was 84 months (range, 24–156). By the last follow-up, the post-operative range of motion, Harris Hip Score, Knee Society Score (KSS) clinical, KSS functional, Western Ontario and McMaster Universities Index of Osteoarthritis (WOMAC) hip, and WOMAC knee scores were significantly improved compared to the preoperative values. All patients achieved the ability to walk. In addition, overall satisfaction scores on a 100-point scale were 92.5 after THA and 89.6 after TKA. Only one patient underwent revision surgery due to knee joint instability, and all replaced hips and knees were radiographically stable by the assessment of the radiolucent line. The proportion of implants that did not suffer loosening or require revision surgery was 99.2% during the 84-month follow-up, based on Kaplan-Meier analysis. Conclusions Our study suggests that bilateral cementless THA and cemented PS-TKA provides reliable mid-long-term clinical, patient-reported, and radiographic outcomes in RA patients, with high survivorship and patient satisfaction.

Background: The present study investigates the clinical and radiographic outcomes in patients with all 4 major lower extremity joints replaced.Methods: A retrospective review of our institution's database identified 125 patients in whom both hips and both knees were replaced. The mean time between the first and last arthroplasty was 6.6 years. Preoperative diagnoses included osteoarthritis in 80% and rheumatoid arthritis in 20%. The average age at the time of the first arthroplasty was 63.7 years. The mean follow-up for all arthroplasties was 10.5 years (range 2-31 years). Patients were then matched according to age, gender, diagnosis, prosthesis, and follow-up, to patients with single or bilateral total hip or total knee arthroplasty.Results: There were 11 aseptic hip revisions (4.4%) and 3 aseptic knee revisions (1.2%). At final follow-up, 86% of hips and 83% of knees were rated with no or mild pain, 68% of patients rated walking as unlimited, and 98% of patients were able to satisfactorily negotiate stairs. Aseptic survivorship for all joint arthroplasties was 93.8% at 15 years. No statistical differences were noted in pain, function, stair, and walking scores between the matched groups.Conclusion: This report demonstrated excellent clinical, functional, and radiographic outcomes in patients with all 4 major lower extremity joints replaced. Walking aids were needed in 15% of patients, however. At final follow-up, this selected group of patients appears to fare just as well as patients with single or bilateral hip or knee arthroplasty with respect to pain and function. [ABSTRACT FROM AUTHOR]
