Objective:
To investigate the long-term efficacy of rehabilitation following arthroscopic synovectomy in patients with rheumatoid arthritis treated with biologic agents.
Methods:
Arthroscopic synovectomy was performed in 29 joints of 17 patients, which were divided into two groups. Group 1 included arthroscopic synovectomy plus rehabilitation for 19 joints in 10 patients, and group 2 included arthroscopic synovectomy without rehabilitation for 10 joints in 7 patients. The Disease Activity Score C-reactive protein (DAS28-CRP), Health Assessment Questionnaire-Disability Index (HAQ-DI), and Functional Independence Measure (FIM) values (motor subscale) at 9.7 years after arthroscopic synovectomy were evaluated to identify the clinical factors related to outcomes.
Results:
The increase in FIM score was significant in group 1 (p=0.05). HAQ-DI at 9 years was significantly decreased in group 1 (p=0.02). Therefore, arthroscopic synovectomy with rehabilitation was significant in improving FIM and HAQ-DI scores over a long period. Multiple regression analysis of FIM scores at 9 years indicated that rehabilitation (p=0.03) and disease duration (p=0.02) were significantly related to outcomes. FIM score at 9 years was significantly negatively correlated with disease duration (p=0.01, r=-0.58, Y=88.89-0.21X).
Conclusion:
Rehabilitation following arthroscopic synovectomy was effective in achieving high FIM scores over time in patients with rheumatoid arthritis.
