Rotator Cuff Patch

Revolutionizing Rotator Cuff Repair with the Regeneten Patch.

Dr Dorf Rotator Cuff & Shoulder Regeneten Patch Surgery

Rotator cuff tears come in many different shapes and sizes:

  • Full-thickness rotator cuff tears: This means that some of the rotator cuff is completely torn off of the bone.
  • Partial-thickness Rotator cuff tears: This means that the rotator cuff may be torn, but at no point is it completely detached from the bone.

The decision to fix a full-thickness rotator cuff tear is simple. Active patients who have pain or weakness because of their tear do well when we fix the rotator cuff.

The decision to fix a partial thickness tear can be difficult. The standard technique for fixing partial-thickness tears involves completing the tear, and then repairing it in the standard fashion, like a full thickness tear. Some of the cuff may be perfectly fine, so deciding to complete the tear is not easy. We estimate the percentage of the cuff that is torn and then fix tears that are torn more than 50%.

How does Regeneten change this decision making process?

By placing a Regeneten patch over a partial thickness tear, we can keep the remaining cuff intact and then add thickness to it with the patch. We can be more aggressive with our decision to fix the cuff, without having to put patients through the long rehab process associated with a full thickness cuff tear.

How does the Regeneten patch work?

The Regeneten patch is placed over the partial thickness tear. The rotator cuff then grows into the patch, adding thickness above the degenerated portion of the cuff. This additional thickness takes stress off of the degenerated part of the cuff, allowing it to heal. MRI studies typically demonstrate 2-3 mm of increased thickness of the rotator cuff after fixing it with the Regeneten patch.

Progression of Healing

What about results?

I have been using the Regeneten patch for 2 years now, and I have had excellent clinical results. The rehab process is 1/2 as long and patients are able to start working on active and passive motion of the shoulder earlier in this process. Most patients who we have performed rotator cuff repair with the patch are back to most of their normal activities by four months.

Show me the evidence?

The evidence for fixing rotator cuffs with the Regeneten patch is convincing. The most convincing studies are MRI studies and they look at the thickness of the cuff before and after placing the patch. I like MRI studies because they are subjective. I have attached references to these studies below if you are interested.

How to know if you are a candidate for fixing your rotator cuff with the patch?

An MRI will show us the extent of tearing in your rotator cuff. If the tearing is less than about 70%, and your cuff looks healthy then you may be a candidate for a repair with the Regeneten patch. If you are in need of rotator cuff and shoulder Regeneten patch surgery, call and schedule an appointment with me and we can go over your MRI together. If you have not yet had an MRI, make an appointment with us and we will get this ordered for you.
