No Superior Bone Union Outcomes with Allografts Compared to No Grafts and Autografts Following Medial Opening Wedge High Tibial Osteotomy: A Retrospective Cohort Study.

For MOWHTOs with an average gap opening width of 12.1 mm, autografts resulted in superior bone union outcomes compared to allografts and no graft at 1 year postoperatively. However, no bone graft achieved similar outcomes to allografts, suggesting that routine use of allografts should not be recommended.
