Some surgeries involve internal fixation with an adjustable double\u2010loop plate, anterior\u2010to\u2010posterior suture suspension fixation, hollow lag screw fixation, and steel wire fixation. In this case, an X\u2010shaped knot and double posteromedial portals are used to retain the posterior septum for fixation. In this technique, we describe double posteromedial portals are used in this method. The internal joint is fixed with an X\u2010shaped knot, and the external joint is fixed with SwiveLock, which puts the wire belt binding PCL compression bone block in a perfect tension state. This surgical technique can achieve a sound functional reduction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Technique
