Abstract:
A young patient presented with a progressive right knee pain and swelling that was worse on ambulation. Following appropriate investigations, he was confirmed having Ewing's sarcoma of the right patella. Two cycles of chemotherapy were initiated before he sustained a fall and a resultant pathological patellar fracture. He finally underwent a total right patellectomy and extensor mechanism reconstruction using Achilles tendon allograft in an attempt to eradicate the disease and salvage his knee extensor mechanism. At 1-year follow-up, no disease recurrence was observed, and the patient had a full range of motion but with slight weakness of the extensor mechanism.
