Editorial Commentary: Size Does Matter-Anterior Cruciate Ligament Graft Diameter Affects Biomechanical and Clinical Outcomes.

Anterior cruciate ligament (ACL) graft strength is related to graft diameter and how ACL grafts heal. All grafts appear to lose strength during healing. Clinical studies have documented that hamstring grafts less than 8 mm wide are more vulnerable to failure. Tripling the semitendinosus allows to increase the graft diameter and strength. A recent study documents a semitendinosus tripling technique with excellent clinical results.
