Yoon JR, et al. - This review of patients who underwent primary total knee arthroplasty (TKA) using autogenous onlay bone graft (AOBG) without the additional allogenous bone or metal augments, revealed the benefits of this simple and reliable AOBG supplement technique. Data indicated that this technique may biologically promote graft to host bone healing by enhancing fixation stability without the additional fixatives and assist the surgeon in managing the varying nature of uncontained bone defects.
