Summary
Total ankle replacement in rheumatoid arthritis patients showed poor clinical outcomes, with high rates of pain and component issues. Despite poor results, patient satisfaction remained surprisingly high.
Area of Science:
- Orthopedics
- Rheumatology
Background:
- Rheumatoid arthritis commonly affects the ankle joint, leading to pain and disability.
- Total ankle replacement is a surgical option for end-stage ankle arthritis in rheumatoid arthritis.
Purpose of the Study:
- To evaluate the long-term clinical outcomes and implant survival of total ankle replacements in patients with rheumatoid arthritis.
Main Methods:
- Retrospective review of 21 patients with rheumatoid arthritis undergoing total ankle replacement between 1984 and 2000.
- Average follow-up of 72 months.
- Clinical outcomes assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) score; radiographic evaluation for complications.
Main Results:
- 12 out of 21 ankles (57%) had poor clinical outcomes.
- High incidence of residual pain (13 ankles), radiolucent lines, tibial component migration (13 ankles), and talar collapse (9 ankles).
- Three ankles required revision surgery.
Conclusions:
- Total ankle replacement in rheumatoid arthritis patients demonstrated a high failure rate and significant radiographic complications.
- Despite poor clinical results, patient satisfaction was not significantly compromised.
