BONE LESIONS, BENIGN BONE TUMORS, RECURRENCE
To our knowledge, the present study represents the first randomized study comparing filling materials for pediatric bone lesions. Benign bone lesions had a high risk of recurrence (averaging 43%) at 2 years after intralesional curettage and filling with either allograft or bioactive glass in the present study, with no differences in any outcome between groups.Previous studies had suggested the risk of recurrence to be low after intralesional excision of benign bone tumors and filling with bioactive glass
