Identical suture material (Ethibond #2) and a four\u2010strand suture configuration were used in all groups. Prior to fixation, computed tomography (CT) scans measured bone mineral density (BMD) and cortical thickness. Biomechanical testing simulated early postoperative loading using a universal testing machine: preload (20\u2009N for 30\u2009s), cyclic loading (500 cycles, 20\u2013100\u2009N at 1\u2009Hz) and a load\u2010to\u2010failure test (20\u2009mm\/s). As primary outcome, ultimate load to failure was recorded; secondarily, cyclic elongation and stiffness were measured.
