“…Previous studies using the lateral approach to harvest bone graft from the proximal tibia found that the non-compressed volume was 5-42 ml 3,9,10,14,21 and compressed cancellous bone was 3.5-15 ml 4,9,14 . For the medial approach, previous studies showed the volume of non-compressed bone grafts ranged from 14 to 40 ml 6,7,20 and from 12 to 35 ml for the compressed bone volume 5,7,12 , which are higher than those of the present study.…”
