Use of Tibial Cortical Autograft for the Osteotomy Site in Medial Opening-Wedge High Tibial Osteotomy Orthopaedic J. Sports Med. (IF 2.6) Pub Date : 2024-03-11 Cumhur Cevdet Kesemenli, Serdar Demiroz, Kaya Memisoglu, Cengiz Erdemir, Ömer Yonga, Faruk Temez, Emre Karadeniz
Background:Medial opening-wedge high tibial osteotomy (OWHTO) is a useful treatment option in patients with medial compartment osteoarthritis. Typically, the osteotomy site is filled with material such as autologous bone graft, allograft, or synthetic bone substitute. However, all these options have disadvantages.Purpose/Hypothesis:The purpose of this study was to describe tibial cortical autograft

Comparison of Outcomes After Primary Versus Salvage Osteochondral Allograft Transplantation for Femoral Condyle Osteochondritis Dissecans Lesions Orthopaedic J. Sports Med. (IF 2.6) Pub Date : 2024-03-07 Clayton W. Nuelle, Kylee Rucinski, James P. Stannard, Richard Ma, Mauricio Kfuri, James L. Cook
Background:Osteochondral allograft transplantation (OCAT) allows the restoration of femoral condyle osteochondritis dissecans (OCD) lesions using an osteochondral unit. When OCD lesions are irreparable, or treatments have failed, OCAT is an appropriate approach for revision or salvage surgery. Based on its relative availability, cost-effectiveness, lack of donor site morbidity, and advances in preservation
