Anterior cruciate ligament (ACL) repair has historically had poor outcomes and fell out of favor in the 1980s with the majority of surgeons opting to do an ACL reconstruction instead due to the high failure rate. The Bridge-Enhanced ACL Restoration or BEAR technique utilizes a de-cellularized, bovine-derived, type I collagen implant to aid in the ACL repair. The device is implanted to augment the healing of the ACL.
The BEAR technique is indicated to augment ACL repair in cases of complete rupture where there is a residual tibial stump of sufficient length and good tissue quality.
In our experience to date, patients undergoing an ACL repair with BEAR recover range of motion quickly and have less quadriceps atrophy and less postoperative swelling than those undergoing ACL reconstruction requiring autograft harvest. We will continue to follow up our patient cohort to assess for re-rupture rate as they return to sport.
The BEAR technique is a promising development that enables ACL repair as an alternative option to reconstruction. This article describes our approach including tips and tricks to successfully perform this procedure.

从历史上看，前交叉韧带（ACL）修复的效果不佳，在20世纪80年代失宠，由于失败率高，大多数外科医生选择进行ACL重建。桥接增强ACL修复术（BEAR）使用一种脱细胞、牛源I型胶原蛋白植入物来辅助ACL修复。该装置被植入以促进ACL的愈合。
BEAR技术适用于完全断裂且胫骨残端有足够长度和良好组织质量的病例，以增强ACL修复。
根据我们目前的经验，与需要自体移植物采集的ACL重建患者相比，接受BEAR ACL修复的患者恢复活动范围更快，股四头肌萎缩更少，术后肿胀也更少。随着患者恢复运动，我们将继续随访我们的患者队列，以评估再断裂率。
BEAR技术是一项有前景的进展，使ACL修复成为重建的替代选择。本文描述了我们的方法，包括成功实施该手术的技巧和窍门。
