Abstract

Aim: The purpose of the study was to evaluate the functional and radiological results of bone grafting combined with cementing with a gel foam mettle (sandwich technique) in osteolytic lesions around the knee, which include Giant cell tumors and Chondromyxoid fibroma, and Chondroblastoma.
Materials and Methods: We had 14 patients of such tumours who were evaluated and treated with extended curettage phenol painting followed by reconstruction of the cavity using a layer of gel foam followed by bone graft and bone cement. The modified technique which we followed included gel foam followed by bone graft followed by another layer of gel foam then bone cement. The period of study was from 2015 to 2019. With average follow up of 2 years.
Result: The results were evaluated using the musculoskeletal tumor society scoring (MSTS) and average score in our patient was 24. There were no recurrence noted as lysis of more than 5mm at bone cement interface.
Conclusion: We conclude that Modified Sandwich technique provided better prognosis and early resuming of activity. This technique with low rate of recurrence can be applied to all juxta articular tumors with good to excellent results. The only drawback of series was a short follow up.
