Double bundle posterior cruciate ligament reconstruction technique: University of Pittsburgh approach

Posterior cruciate ligament (PCL) reconstruction has traditionally focused on the larger and stronger anterolateral bundle. Persistent low-grade laxity frequently occurs with this technique. Recent biomechanical data has shown that reconstruction of the posteromedial bundle, in addition to the anterolateral bundle, more closely restores knee kinematics to normal. Therefore, this type of "double-bundle" reconstruction may be superior to "single" bundle techniques. This article addresses the basic science rationale behind double bundle PCL reconstruction and discusses in detail the technique used at the University of Pittsburgh.
