Abstract
Methodology: In this prospective case series 16
skeletally mature patients with primary giant cell
tumor around the knee were included. Patients
with previous surgically treated, malignant
transformation, degenerative knee changes and
those presenting with pathological fracture were
excluded. The tumor was excised with bone graft
filling space beneath the articular cartilage and a
block of gel foam was placed over the cortical
surface of picked bone graft. Remaining cavity
was filled with polymethylmethacrylate cement
(sandwich) with or without internal fixation. The
func tional evaluation was done us ing
Musculoskeletal Tumor Society (MSTS) Score six
months postoperatively and after one year.
Schatzker and Lambert Score was used in the last
visit to assess the functional outcome
Results: The mean MSTS Score was
27.13±3.030 (range, 20-30) and the mean
functional arc of motion around the knee was
123.13±12.230 degrees (range, 90–135).
According to Schatzker and Lambert Score 75%
had excellent results, 12.5% had good results and
12.5% had fair results. Two patients (12.5%) had a
recurrence of the tumor, and one (6.25%)
developed postoperative fracture in the distal
femur.
Objective: To evaluate the functional outcomes
after extended curettage and reconstruction using
a combination of bone graft and bone cement
(sandwich).
Conclusion: Sandwich reconstruction for giant
cell tumor is a good option for definite
management and there is improvement in the
quality of the patient's life. (Rawal Med J
