A case series of Osteoclastoma around knee with pathological fracture-treated with joint salvage surgery using sandwich technique augmented with locking plate: A prospective study

This study is done to evaluate outcomes of 18 patients who underwent curettage, use of phenol, and reconstruction using the sandwich technique for Giant Cell Tumour (GCT) with pathological fracture of the bone around the knee. 12 men and 6 women aged 19 to 46 (mean-30.7 years ) years underwent intralesional curettage, use of phenol, and reconstruction using the sandwich technique for GCT augmented with locking plates of the proximal tibia (n=6 ) or distal femur (n=12). 10 and 8 tumours were classified as grade II, and grade III, respectively. Patients underwent intralesional curettage, use of phenol, and reconstruction with allograft, gel foam, and cement (the sandwich technique) Pathological fractures were fixed with plates. Functional outcome was evaluated using the Musculoskeletal Tumor Society (MSTS) score: The follow-up period was 2 years. The mean MSTS score was 28 out of 30 (standard deviation, 3; range, 16-30). One patient with a grade III tumour in the proximal tibia had a recurrence detected elsewhere after 1 year. Her MSTS score at 2 years was 26. No patient had a malignant transformation. Intralesional curettage, use of phenol, and reconstruction with allograft, gel foam, and cement (the sandwich technique) for GCT of bone achieved good functional outcomes and a low recurrence rate
