Bipartite patella associated with tophaceous invasion: A rare case report

Abstract

We report the case of 32-year-old male who had a painful knee due to tophus formation in the interosseous area of the bipartite patella. There was neither a history of previous trauma to his patella nor a family history of gouty arthritis. Intraoperatively, we found chalky white-yellow material deposited at the bipartite space and it was curetted. The second part of the patella was fixed by a screw for functional preservation. In addition, hyperuricemia was also noted and controlled by uricosuric agents postoperatively. Gout should be included in the differential diagnosis of painful bipartite patella, and we suggest surgical intervention in combination with antihyperuricemic therapy for tophaceous deposits of the bipartite patella.
