Abstract

Introduction Arthroscopic synovectomy of the knee is one of the less invasive surgical procedures of the resection of synovium in patients with chronic synovial hypertrophy inflammation. Some rheumatologists doubt in the effectiveness of such procedure. In their opinion the JIA is a systemic disease whereas the synovectomy is restricted to selected joints only.

Objectives It was decided to present the results of our synovectomy procedure and to evaluate the effectiveness of this method during 6,5 year observation.

Material and methods 15 patients of the age 7-23 (mean 15.5) with JIA (10 girls and 5 boys) were submitted to arthroscopic synovectomy in the Department of Pediatric Orthopedics and Traumatology, Medical University of Bialystok (in 2001-2007). In one case both knee joints were operated. In all cases the disease process took about 3 years.

Results The most important symptoms of recovery was significant reduction of the oedema in the joint area and a decrease in the volume of intraarticular exudate. Unfortunately, the procedure did not improve the range of motion. In a short periodof observation was significantreduction of pain.

Conclusions It seems that the surgical reduction in the volume of intraarticular inflammatory tissue evokes the formation of new synovium with lower metabolic activity. Such a newly formed tissue does not exert a disruptive role on the articular cartilage. The newly formed synovium allows better penetration of antirheumatic drugs and increases the effectiveness of treatment.
