Partial resection of the PCL insertion site during tibial preparation in cruciate-retaining TKA.

Purpose: Based on the anatomy of the tibial PCL insertion site, we hypothesized that at least part of it is damaged while performing a standard tibial cut in a PCL-retaining total knee replacement. The purpose of this study was to determine and quantify the amount of resection of the tibial PCL attachment with a 9 mm tibial cut with 3 degrees of posterior slope.

Methods: Twenty cadaver tibias were used.
