Recurrent Giant Cell Tumor of the Distal End of the Femur

INTRODUCTION: The aim of the study was a case report of a right-sided recurrent giant cell tumor of the distal end of the femur. METHODOLOGY: A case of a 25-year-old male patient with a history of recurrent giant cell tumor of the right distal femur who presented with chief complaints of pain over right distal femur and stiffness in the right knee for 2 years with restricted knee movement and is unable to walk. He was diagnosed with recurrent giant cell tumor of the right of the distal femur and was treated with wide excision with mega prosthesis reconstruction. RESULT: Wide excision with mega prosthesis reconstruction showed a good functional range of motion with early rehabilitation, stability, and mobility of joints. CONCLUSION: We recommend wide excision and reconstruction with mega prosthesis is an effective method compared to sandwich technique and nailing and can be successfully done in the case of recurrent giant cell tumor of the distal femur with a good outcome, functional range of motion, stability, and mobility of the joint with early rehabilitation though it is a technically demanding surgery. The knee joint could have been salvaged and the need for more extensive surgery could have been prevented, had the diagnosis of recurrent giant cell tumor was made earlier.
