Intraarticular tophi in a joint without a previous gouty attack

Area of Science:

• Rheumatology
• Orthopedics
• Crystal Arthropathies

Background:

• Subcutaneous tophi are typically a late sign of gout.
• Intraarticular tophi are thought to precede acute gout attacks due to crystal shedding.
• Evidence for intraarticular tophi before the first gout attack is limited.

Observation:

• A patient with a 3-year history of gout presented without subcutaneous tophi.
• During knee arthroscopy for a ligament tear, intraarticular whitish deposits, likely urate tophi, were observed.
• This finding suggests tophi can form in joints before external signs appear.

Findings:

• The case demonstrates that intraarticular tophi can manifest early in the course of gout.
• Joints previously unaffected by gout symptoms can still harbor tophi deposits.
• This challenges the traditional view of tophi development as a solely late-stage phenomenon.

Implications:

• Early intraarticular tophi may be more common than previously recognized.
• This finding could influence diagnostic approaches and treatment timing for gout.
• Further research is needed to understand the early pathogenesis and clinical significance of intraarticular tophi.
