Functional Outcome of Extended Curettage and Reconstruction Using Sandwich Technique for Giant Cell Tumor Around Knee/ Distal Radius

Abstract

Introduction: Giant cell tumor (GCT) of bone is a relatively common, locally aggressive primary bone neoplasm that typically affects young adults between the ages of 20 and 40 years. It accounts for approximately 5% of all primary bone tumors and 20% of benign bone tumors.
Aim: To evaluate the functional outcome of extended curettage and reconstruction using the sandwich technique in patients with giant cell tumor around the knee and distal radius, highlighting its effectiveness as a limb-sparing procedure.
Methods: This study was a prospective observational study conducted to evaluate the functional outcome of extended curettage and reconstruction using the sandwich technique in patients with giant cell tumor around the knee and distal radius.
Results: Extended curettage and sandwich technique were performed in all patients 15 (100.0%). Bone graft was used in 11 patients (73.3%), while 4 patients (26.7%) did not receive a bone graft. PMMA cement was used in all cases 15 (100.0%). Internal fixation was performed in 8 patients (53.3%), whereas 7 patients (46.7%) did not undergo internal fixation.
Conclusion: The present study demonstrates that extended curettage followed by reconstruction using the sandwich technique yields favorable functional outcomes in patients with giant cell tumor around the knee and distal radius. The majority of patients achieved excellent to good results, indicating effective tumor clearance combined with preservation of joint function.
