Twenty\u2010eight patients had single\u2010bundle reconstruction (group S) and 31 received double\u2010bundle reconstruction (group D). Ligament stability was assessed with the Lachman and pivot\u2010shift tests and a KT\u20102000 arthrometer.

Regarding the pivot\u2010shift test, 3 patients had grade 1+ and 1 patient had grade 2+ pivot\u2010shift in group S, while no patients had abnormal pivot\u2010shift in group D (\n                      <jats:italic>P<\/jats:italic>\n                      = .093).
