Non-Specific Synovitis of the Knee in Children: Arthroscopic Management

Abstract

Chronic non-specific synovitis is a recurrent proliferative lesion which usually involves a single joint. The main symptoms are pain and swelling. A definitive diagnosis is based on histopathologic findings. This synovial sample is usually obtained by trocar biopsy in adults and more challenging in children and sometimes unachievable. Knee arthroscopy could be performed for biopsy and local treatment (synovectomy).
