Anterior cruciate ligament reconstruction (ACLR) is one of the most common orthopedic procedures performed each year. The majority of patients undergoing these reconstructions will experience long-term stability and symptomatic relief; however, some will require a revision ACLR procedure. In general, revision ACLRs are more challenging than primary ACLRs due to several diagnostic and technical considerations. A revision ACLR can be performed with either a one-stage or two-stage procedure, which is based on the presence or absence of malpositioned tunnels, bone loss, and tunnel expansion. Recently, the introduction of preshaped allograft bone dowels as a bone grafting option has gained popularity. They provide immediate structural stability and avoid donor site morbidity associated with autografts. The purpose of this article is to outline a bone-grafting tunnel technique with cannulated allograft bone dowels soaked in bone marrow aspirate concentrate (BMAC) used in the first stage of a staged revision ACLR procedure.
前交叉韧带重建术（ACLR）是每年进行的最常见的骨科手术之一。大多数接受这些重建手术的患者将获得长期稳定性并缓解症状；然而，一些患者将需要进行翻修前交叉韧带重建手术。一般来说，由于多种诊断和技术因素，翻修前交叉韧带重建术比初次前交叉韧带重建术更具挑战性。翻修前交叉韧带重建术可采用一期或二期手术，这取决于隧道位置不良、骨丢失和隧道扩大的情况。最近，预成型同种异体骨栓作为一种骨移植选择已受到欢迎。它们提供即时的结构稳定性，并避免与自体移植相关的供区并发症。本文的目的是概述一种在分期翻修前交叉韧带重建手术的第一阶段中使用浸泡在骨髓抽吸浓缩物（BMAC）中的空心同种异体骨栓的骨移植隧道技术。
