Tuberculous Osteomyelitis of the Patella

Abstract

Patellar tuberculosis is a rare occurrence despite the knee being the third most common osteoarticular site to be involved. This is the reason for its late diagnosis and the potential to spread posteriorly to the knee. We present an atypical case of patellar tuberculosis in an 8-year-old boy presenting with discharging sinus and diagnosed by biopsy.
