Anterior Cruciate Ligament Allograft Reconstruction Augmented With a Reinforced, Bioinductive Collagen Scaffold in the Setting of Multiligamentous Knee Injury

The gold standard for surgical treatment of anterior cruciate ligament (ACL) injuries is reconstruction. There are a variety of graft options, from autograft to allograft, using bone-patellar tendon-bone (BTB), hamstrings, quadriceps, or Achilles, and, in the case of a multiligamentous knee injury (MLKI), allograft may be preferred to decrease operative time and graft harvest morbidity. The BioBrace (ConMed, New Haven, CT) is a bioinductive collagen scaffold designed to provide an environment for soft tissue remodeling with time zero biomechanical support and can be used to augment graft reconstructions in the case of concerns for allograft strength, healing, or width. The purpose of this Technical Note is to describe the technique for performing an ACL reconstruction with BioBrace-augmented allograft in the setting of a MLKI, with special consideration for 2 methods of graft preparation (BTB and soft tissue).
