ABSTRACT
The posterior cruciate ligament (PCL) is recognized to be the main posterior stabilizer of the knee. PCL injuries often occur in the setting of multiligament injuries and also with concomitant chondral and meniscal lesions. In general, acute grade I-II PCL injuries can be treated conservatively. However, for acute grade III PCL injuries or multiligament injuries surgery is advocated. Anatomic single-bundle PCL reconstruction (PCLR), which focuses on reconstructing the larger anterolateral bundle (ALB), is the most commonly performed procedure. Due to the residual posterior and rotational tibial instability after a single-bundle reconstruction procedure and its inability to restore normal knee kinematics, an anatomic double bundle (DB) PCLR has emerged as a potentially superior technique from an anatomical and biomechanical aspect. The purpose of this article was to review the specific principles of PCL anatomy, biomechanics,
injury diagnosis and treatment options, focused on arthroscopic double-bundle PCL reconstructions and review of the current literature of PCL reconstruction techniques.
