Augmentation of triceps tendon repair with a bio-inductive collagen scaffold

Two active, adult male patients, one with prior triceps rupture and direct repair, presented with traumatic rupture of the distal triceps tendon. MRI confirmed not only complete rupture with retraction in both, but also signal changes within the tendon, raising concern for healing potential and re-rupture. Surgical repair was performed using heavy, non-absorbable suture and suture anchors in the standard fashion, followed by augmentation with a bovine, bio-inductive collagen scaffold in order to increase tendon thickness and aid with healing capability. This technique is well described for rotator cuff repair augmentation but is a novel technique to the literature in the setting of triceps tendons repair. Both patients returned to full, preinjury activity without complication with sustained results at 3 and 3.5 years postoperatively.
