RESUMEN
Posterior cruciate ligament (PCL) plays an important role in maintaining the stability of knee. PCL injury is often accompanied by serious axial and rotational instability, and severe PCL injury is likely to be combined with injuries to the anterior cruciate ligament, medial collateral ligament and other tissues which are often repaired by necessary posterior cruciate ligament reconstruction (PCLR) to restore their physiological functions. However, PCLR research is not as common as the research into the anterior cruciate ligament reconstruction, not only due to controversies in the anatomy and mechanics of PCL but also due to a higher failure rate and more complications following PCLR. This situation is closely related to the anatomical characteristics of the PCL tibial insertion. The present review deals with the anatomy, mechanics and clinical research of the PCL tibial insertion in order to provide more references for PCLR operators.
