Posterior cruciate ligament reconstruction by means of tibial tunnel: anatomical study on cadavers for tunnel positioning.

Objective: to determine the reference points for the exit of the tibial guidewire in relation to the posterior cortical bone of the tibia.

Methods: sixteen knees from fresh cadavers were used for this study. Using a viewing device and a guide marked out in millimeters, three guidewires were passed through the tibia at 0, 10 and 15 mm distally in relation to the posterior crest of the tibia.

Immunohistochemical analysis of mechanoreceptors in the human posterior cruciate ligament: association with aging male.

Introduction: The aim of this study was to evaluate the association between frequency of the posterior cruciate ligament (PCL) mechanoreceptors and age in men.

Methods: Nineteen normal right knees harvested from human male cadavers were evaluated. Age ranged from 17 to 64 years with a mean of 35 years old.
