Ambiguity of Primary Patellar Tuberculous Osteomyelitis as a Pre-Patellar Bursitis A Case Report

Case: A 47-year-old male with swelling over the patella and associated pain, subsiding with medicines but recurring after a few days. Diagnosed as prepatellar bursitis by the family physician, it eventually turns out to be osteomyelitis of the patella. Treated with curettage, biopsy, and placement of biocomposite mixed with antibiotics. Intra-operative findings and histopathology confirmed tuberculosis of the patella. On follow-up after 6 years and the completion of anti-tuberculosis treatment, the patient showed full functional and radiological recovery without recurrence. Conclusion: Early treatment with antibiotics and surgery gives excellent results. Identifying it as a tuberculous osteomyelitis is challenging when the condition is closely resembles pre-patellar bursitis.
