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].
