Knee synovectomy for rheumatoid arthritis

Area of Science:

• Orthopedic Surgery
• Rheumatology

Background:

• Rheumatoid arthritis (RA) commonly affects the knees, causing pain and synovitis.
• Synovectomy is a surgical option for managing RA knee joint inflammation.

Purpose of the Study:

• To evaluate the long-term outcomes of knee synovectomy in patients with rheumatoid arthritis.
• To determine the efficacy of synovectomy in reducing pain, synovitis, and preserving motion.

Main Methods:

• Retrospective analysis of 33 knee synovectomies in 21 rheumatoid arthritis patients.
• Average follow-up of 5 2/3 years post-operation.
• Assessment of pain, synovitis, patient satisfaction, radiographic progression, and joint motion.

Main Results:

• 58% of knees reported less pain, 15% more pain post-surgery.
• 54% of patients were satisfied with the outcome.
• Palpable synovitis decreased, with all knees showing lesser synovitis objectively.
• 53% of knees demonstrated radiographic progression; no loss of motion occurred.
• No significant complications were reported.

Conclusions:

• Knee synovectomy provides beneficial outcomes for rheumatoid arthritis patients, including pain relief and reduced synovitis.
• Early surgical intervention in knees with minimal radiographic destruction and deformity may yield better results.
• The procedure is recommended for continued use due to its benefits, even with potential long-term radiographic changes.
