A total of 61 New Zealand white rabbits were used, with 23 donor rabbits for harvesting B-ACL-B allografts and 38 recipient rabbits undergoing unilateral ACL reconstruction with B-ACL-B allograft. Animals were euthanized for biomechanical testing, micro-computed tomography examination, histological analysis, multi-photon microscopy and transmission electron microscopy testing at 2, 4 and 8 weeks after surgery. Gross inspection and radiographs confirmed the intact ACL allograft in the proper anatomic position. Progressive healing occurred between the bone block and the bone tunnel as demonstrated by a gradual increase in average bone volume fraction and total mineral density at 4 and 8 weeks. Histological analysis showed new bone formation at the bone block\u2013tunnel interface, with maintenance of the native ACL enthesis. Ultrastructural analysis demonstrated the maintenance of overall collagen matrix alignment, while there was repopulation with smaller diameter collagen fibrils. There was no significant difference between 4 and 8 weeks in mean failure force (p = 0.39) or stiffness (p = 0.15) for the B-ACL-B allografts. This study demonstrates the restoration of the normal anatomy of the ACL and progressive graft incorporation and remodeling using a B-ACL-B allograft for ACL reconstruction in the rabbit knee.<\/jats:p>","DOI":"10.3390\/jcm12227057","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T02:46:47Z","timestamp":1699843607000},"page":"7057","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Short-Term Evaluation of Bone\u2013ACL\u2013Bone Complex Allograft in ACL Reconstruction in a Rabbit Model"],"prefix":"10.3390","volume":"12","author":[{"given":"Yulei","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Sports Medicine, Peking University Third Hospital, Beijing 100191, China"},{"name":"Orthopedic Soft Tissue Research Program, Hospital for Special Surgery, New York, NY 10021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janice","family":"Havasy","sequence":"additional","affiliation":[{"name":"Orthopedic Soft Tissue Research Program, Hospital for Special Surgery, New York, NY 10021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel","family":"Green","sequence":"additional","affiliation":[{"name":"Orthopedic Soft Tissue Research Program, Hospital for Special Surgery, New York, NY 10021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang-Hua","family":"Deng","sequence":"additional","affiliation":[{"name":"Orthopedic Soft Tissue Research Program, Hospital for Special Surgery, New York, NY 10021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daoyun","family":"Chen","sequence":"additional","affiliation":[{"name":"Orthopedic Soft Tissue Research Program, Hospital for Special Surgery, New York, NY 10021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Piacentini","sequence":"additional","affiliation":[{"name":"Orthopedic Soft Tissue Research Program, Hospital for Special Surgery, New York, NY 10021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott A.","family":"Rodeo","sequence":"additional","affiliation":[{"name":"Orthopedic Soft Tissue Research Program, Hospital for Special Surgery, New York, NY 10021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"202","DOI":"10.1016\/j.arthro.2009.07.014","article-title":"Anatomic Double-Bundle Anterior Cruciate Ligament Reconstruction: Kinematics and Knee Flexion Angle\u2013Graft Tension Relation","volume":"26","author":"Murray","year":"2010","journal-title":"Arthroscopy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"412","DOI":"10.1177\/036354658301100606","article-title":"Anterior cruciate-deficient knees: A review of the literature","volume":"11","author":"Rovere","year":"1983","journal-title":"Am.
