Objective: To report the use of a pedicled patellar transplant (d’ Aubigne procedure) in the reconstruction of femoral condyle for unicondylar giant cell tumours, in developing countries where facilities for custom made prostheses are not widely available.

Case Report: A 28 year old male presented with 5 month history of left knee joint swelling and pain and 1 month history of inability to walk. X-ray showed eccentric, expansile lytic lesion of the lateral femoral condyle associated with a pathological fracture of the subchondral bone. A diagnosis of Enniking’s stage-III Giant cell tumour was made based on the x-ray and histopathology findings. Due to the associated subchondral fracture, joint reconstruction using custom made prosthesis was considered as an ideal option. But, as this prosthesis was not available, d’ Aubigne procedure was considered as an alternative, in order to preserve the joint. Femoral condyle was removed “en bloc” with the tumour. Patella was prepared with intact vastus lateralis and fixed in continuity and in level with the medial condyle. Gap between the patella and femoral shaft was filled by combined cancellous and cortical grafts from iliac crest and tibia. Post operative course was uneventful. After a follow up of 2 years there was no recurrence and the range of flexion was 90° without any instability and pain.

Conclusion: In patients with unicondylar giant cell tumours with subchondral fractures, arthrodesis can be avoided and the joint can be preserved using pedicled patellar transfer, when arthroplasty can not be carried out.
