Synovectomy of the ankle joint

Area of Science:

• Orthopedic Surgery
• Rheumatology
• Clinical Outcomes

Background:

• Rheumatoid arthritis frequently affects the ankle joint, causing pain, swelling, and functional limitation.
• Synovectomy is a surgical procedure to remove the inflamed synovial membrane, aiming to alleviate symptoms and slow disease progression.

Purpose of the Study:

• To evaluate the long-term effectiveness of ankle joint synovectomy in patients with rheumatoid arthritis.
• To assess the impact of synovectomy on pain, swelling, range of motion, gait, walking distance, and need for walking aids.

Main Methods:

• A retrospective study of 123 ankle synovectomies performed between 1970-1979 on 99 patients.
• Follow-up data for 81 ankles (62 patients) over an average of four years.
• Assessment of disease severity using Steinbrocker's classification (Stages I-IV).

Main Results:

• Over 80% of patients experienced significant reductions in ankle pain and swelling post-surgery.
• Improvements were observed in the range of motion and gait patterns.
• No significant change was noted in walking distance or the requirement for walking aids.

Conclusions:

• Ankle synovectomy is effective in reducing inflammatory symptoms and improving local joint function in rheumatoid arthritis.
• The procedure's impact on overall mobility and functional independence is limited when other lower extremity joints are involved.
