ACL=anterior cruciate ligament.
A comprehensive description of baseline characteristics for all included patients has been published.7
*In one knee, anteroposterior laxity could not be assessed owing to pain; magnetic resonance imaging (MRI) and arthroscopy confirmed total ACL rupture.
†In one knee, anteroposterior laxity was found to be normal at baseline, but MRI and arthroscopy confirmed total ACL rupture.
