Discover the benefits

Request an appointment with us today to learn about about The REGENETEN Bioinductive Implant surgery that has shown consistent healing of rotator cuff tears in both partial and full thickness tears 1,2,8,12.


The REGENETEN Bioinductive Implant

is an innovative technology designed to address the treatment of rotator cuff disease. The REGENETEN Bioinductive Implant offers a new solution that supports the body's natural healing response to facilitate new tissue growth and potentially disrupt disease progression by providing a framework for tissue growth1,2,7-9.

What is it?

The technology includes a collagen based bioinductive implant about the size of a postage stamp. This implant is delivered arthroscopically through a small incision over the location of your rotator cuff tendon injury. Your physician will secure it in place with small anchors.

How does the REGENETEN Bioinductive Implant benefit you?

No matter where you are in the progression of rotator cuff disease, the REGENETEN Bioinductive Implant has shown consistent healing of rotator cuff tears in both partial and full thickness tears 1,2,8,12.

  • Preliminary evidence indicates a reduction in re-tear rates compared to the standard of care in patients with full thickness tears 3,13
  • No tear progression was observed by MRI in any patients at 24 months in a study on partial thickness tears (n=13) 1
  • Clinically meaningful improvements in pain and function scores at one year compared to pre-operation values 14,15
  • The REGENETEN Bioinductive Implant has been shown to be a safe and effective solution in the treatment of rotator cuff disease. 1,2,7,11,12

A new approach – REGENETEN Bioinductive Implant

Until now, surgeons have focused on addressing the mechanics of the shoulder when repairing a rotator cuff injury, but had limited options to address the biology of healing. Traditional rotator cuff repair procedures involve suturing tendon to bone are associated with potentially long rehabilitation and substantial lifestyle interruption. As a result, many people choose to forego surgery until their pain is severe and everyday tasks are affected. However, as rotator cuff disease progresses, it can become increasingly difficult for your surgeon to repair and small tears can grow in severity and size over time 4,5,6.

How does it work?

Progression of healing

The implant is placed on top of the rotator cuff
After implantation, the REGENETEN Bioinductive implant creates an environment that is conducive to healing 1,2,7 and the proprietary composition facilitates the formation of new tissue 1,2,7,10.

The implant induces new tissue growth, increasing tendon thickness 1,2,3.
New tissue allows tendon to restore its natural attachment points in the body3 and is indistinguishable from native tendon at 3 months 1,2,11.

New tissue integrates and remodels into the healing tendon 2,7,11.
Tissue strength comes from the induced tissue, not the implant, which has been shown to be completed absorbed within six months 7,11, *.
