Background:
Gout is a disease of purine metabolism characterized by monosodium urate crystal deposition. Gouty tophi can mimic many conditions such as infection or neoplasm.
Objective:
We descriptively presented a case of a 29-year-old male with gouty toph. Data was obtained from patient chart. This patient presented with limited knee joint range of motion after sport injury. Arthroscopic examination was performed in order to confirm the diagnosis of the meniscal injury.
Results:
The result showed the synovium with white toothpaste-like chalky urate crystals in the joint cartilage.
Conclusion:
An atypical presentation of gouty tophi can sometime mislead to diagnose an internal derangement of the knee.
