ACL/PCL reconstruction: the role of double-bundle PCL reconstruction

Abstract 

Our approach to combined anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) injuries depends on the timing of the injury and concomitant ligament and bony pathology. In the acute setting (within 3 weeks), we prefer to perform single-bundle ACL and PCL reconstruction because we have seen consistently good results. However, chronic combined injuries do not fare as well because single-bundle PCL reconstruction in these injuries has not consistently corrected posterior laxity. Because of this clinical data, we now utilize a double-bundle PCL technique for knees with chronic, combined ligament deficiency with instability. This particular patient population has significant anterior, posterior, and, in many cases, posterior lateral laxity. Once the decision has been made to proceed with this procedure, attention to the technical details is critical to achieving good results. In this article, we will outline important general and specific technical details that will facilitate the procedure and optimize the clinical outcome.
