Arthroscopic Treatment of Isolated Tophaceous Gout of the Knee: A Rare Case Report.

Abstract

Introduction: Isolated tophaceous gout of the knee is an uncommon presentation, requiring a high degree of clinical suspicion for accurate diagnosis. With prompt and appropriate management, favorable patient outcomes can often be achieved.

Case report: We present the case of a 32-year-old male clerk with a 2-year history of chronic knee pain and stiffness. Magnetic resonance imaging revealed joint effusion and synovial hypertrophy. Arthroscopic evaluation identified chalky intra-articular deposits confirming isolated tophaceous gout of knee, and histopathological analysis confirmed gross inflammatory synovial hypertrophy. Surgical debridement and synovectomy, followed by medical management, gave good clinical outcomes.

Conclusion: The treating surgeon should recognize this presentation and choose appropriate arthroscopic and medical management, which can lead to favorable outcomes.
