Extended Curettage and Cement Reconstruction in a Giant Cell Tumour of the Proximal Tibia: A Case Report

Giant cell tumour (GCT) of bone is a benign but locally aggressive neoplasm, frequently involving the epiphyseal region of long bones, particularly around the knee 1-3. We report a case of GCT of the right proximal tibia in a skeletally mature patient who presented with pain and swelling. Radiological evaluation showed a well-defined expansile lytic lesion without evidence of metastasis 1-4. The patient was managed with extended intralesional curettage using a high-speed burr, adjuvant chemical cauterisation, and defect reconstruction with polymethylmethacrylate (PMMA) bone cement 3, 4. Post-operative recovery was uneventful, with excellent knee function and no recurrence at follow-up. Bone cement provided immediate stability, enabled early mobilisation, and facilitated detection of recurrence on imaging 4, 5. This case highlights that extended curettage with adjuvant therapy and cement reconstruction is an effective joint-preserving technique for proximal tibial GCT, offering good functional outcomes and low recurrence rates 3–5.
