title: Chondroblastoma of the distal femur. A case report.
abstract: The authors report a case of chondroblastoma which was localised in the distal femoral epiphysis in a 16-year-old boy. The lesion was large, rapidly expanding and extended into the knee joint. After diagnostic evaluation including tru-cut biopsy, the lesion was treated surgically with curettage and grafting with coralline hydroxyapatite. Four months after surgery the patient had no pain and had nearly full range of motion of the left knee. He was followed up for thirty-five months with routine radiographs and physical examination. He had no recurrence, no pain, and regained full range of motion of his knee. Most chondroblastomas involve the medullary cavity; they may rarely involve the cortex but to the best of our knowledge, no cases with soft tissue involvement have been reported in the literature.
