Knotless double-row suturebridge rotator cuff repairs using wide diameter sutures improves self-reinforcement and footprint compression compared with double-row suturebridge repairs using standard diameter suture material with tied medial knots

Liu VK, Bouwmeester TM, Smith GCS, et al. - A comparison was performed of the self-reinforcement and footprint contact pressure generated under progressive tensile loads between two double-row SutureBridge rotator cuff repair techniques: one performed with FiberWire and one with FiberTape in a knotless technique. In 10 pairs of ovine shoulders, researchers performed rotator cuff repairs. A double-row SutureBridge repair using FiberWire was performed in one group and an identical repair was performed with FiberTape. Measurement of footprint contact pressure was done from 0° to 60° of abduction under loads of 0 to 60 N. Then, they performed pull-to-failure tests. Per outcomes, both double-row SutureBridge repairs showed self-reinforcement with standard diameter suture material and wide diameter suture material but it was greater in the repair with wide diameter suture material construct. Greater footprint compression was observed in knotless double-row SutureBridge repair with wide diameter suture material vs with standard diameter suture material at 20 o of abduction.
