Collagen Patch Regeneten
Reinforce the Torn Tendon with a Bioabsorbable Patch
For bursal-side partial rotator cuff tears, a biocompatible collagen patch is placed over the thinned area to physically reinforce and biologically regenerate the tendon. >70% increase in tendon thickness confirmed post-procedure.
Regeneten — Bioabsorbable Collagen Matrix
Regeneten is a biocompatible collagen patch derived from porcine small intestinal submucosa (SIS). It is placed over the torn bursal surface of the rotator cuff to physically support the tendon while naturally promoting tissue regeneration through collagen scaffold integration.
Which tears is this best for?
Particularly effective for bursal-side (bursal surface) partial tears where the outer surface of the rotator cuff has thinned or partially torn. Unlike articular-side tears (treated with plication suture), bursal-side defects can be physically reinforced with a patch overlay.
Why Regeneten Works
Dual mechanism: physical support + biological regeneration
The patch provides immediate mechanical reinforcement to the weakened tendon, while the collagen scaffold integrates with the native tissue, stimulating cell ingrowth and new collagen synthesis.
Fully bioabsorbable — no permanent foreign material
Over approximately 6 months, the patch is naturally resorbed and replaced by the patient's own tissue. No metal anchors or permanent implants remain in the body.
FDA & CE approved material
Regeneten is a CE-marked and FDA-cleared medical device used globally for rotator cuff augmentation. Its safety and efficacy are well-established in clinical literature.
Best Results When Combined
Regeneten is highly effective alone, but combining it with plication suture produces the strongest outcomes.
Plication Suture + Collagen Patch (Regeneten)
The plication suture anchors the articular-side of the torn tendon to bone from below, while the collagen patch reinforces the bursal surface from above. Together, they address both faces of the tear simultaneously — providing comprehensive structural and biological restoration.
