BACKGROUND Microfracture and drilling are bone marrow-stimulation techniques that initiate cartilage repair by providing access to cell populations in subchondral bone marrow. This study examined the effect of hole depth and of microfracture versus drilling on subchondral bone repair and cartilage repair in full-thickness chondral defects. HYPOTHESES Repaired subchondral bone does not reconst...

background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...

we report 127 cases who have had elective operation on cranium because of skull bone defect during 1984-1989. usually repair of skull bone defect and preserving normal anatomy were the major therapeutic goals. 10, ii in these cases a new surgical technique is described which can successfully accomplish these goals in a single but staged operative procedure.

It has been well recognized that the modification of biomaterials with appropriate bioactive peptides could further enhance their functions. Especially, it has been shown that peptide-modified bone repair materials could promote new bone formation more efficiently compared with conventional ones. The purpose of this article is to give a general review of recent studies on bioactive peptide-modi...

BACKGROUND Traditional Bankart repair using bone tunnels has a reported failure rate between 0% and 5% in long-term studies. Arthroscopic Bankart repair using suture anchors has become more popular; however, reported failure rates have been cited between 4% and 18%. There have been no satisfactory explanations for the differences in these outcomes. HYPOTHESIS Bone tunnels will provide increas...
