Chondroblastoma of the distal femur - management with excision and allograft reconstruction

Chondroblastoma is a rare primary benign tumor of bone commonly affecting older children around the knee, hip and shoulder. The tumor usually involves the epiphysis before closure of the physis .Chondroblastoma can be treated with simple curettage, bone grafting, and possible cementation using similar techniques as for giant cell tumour surgery. These techniques are however plagued by problems such as recurrence, growth disturbances with limb length discrepancy and resultant deformity. We report a 16 years old teenage girl who presented to us with chondroblastoma of the distal femur which was managed with wide excision of the bone lesion and allograft bone grafting using cadaveric femoral head fixed in place with a plate and screws . This resulted in good integration and good function and range of motion
