Brief Summary

The investigator's goal is to determine the effectiveness of stromal vascular fraction (SVF) cell injection to treat small rotator cuff tears without surgery.

Detailed Description

Small rotator cuff tendon tears are a hard task in shoulder care. They are often not operated on because research has not shown any increased benefit of surgery over physical therapy. The most common way to treat these tears is through physical therapy or steroid injections. However, the relief doesn't last very long. Recent studies have shown a lot of tears get worse over time. This happens because the physical therapy options can treat the pain and symptoms, but do not heal the actual tear.

Another non-surgical option for treating small tears is through adipose-derived stem cells. Adipose-derived stem cells are cells that are found in the fat in our bodies. The cells have shown promise in fixing tissues and may provide help to treat small rotator cuff tears. The investigators are studying a part of these fat cells known as the stromal vascular fraction (SVF). The SVF contains a number of cells that are able to become a variety of different cells. This is important because they may be able to turn into cells that may help heal the damaged rotator cuff tendons. These cells have been shown to improve results after rotator cuff surgery, but no research has used these cells to help small tears without surgery. The use of SVF is investigational. "Investigational" means that the drug being tested has not been approved for routine clinical use or for the use described in this study by the United States Food and Drug Administration (FDA). The FDA is allowing the use of this drug for research. The investigators goal is to determine the effectiveness of SVF cell injection to treat small rotator cuff tears without surgery.

Conditions

Rotator Cuff Tears

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: TRIPLE

Study Groups

Fibrin Glue

Single 4 milliliter (mL) injection of 0.9% normal saline and fibrin glue solution

Group Type: ACTIVE_COMPARATOR

Tisseel Injectable Product

Intervention Type: DRUG

Fibrin glue will provide an inert, biocompatible, viscous substance able to remain within the Rotator Cuff (RC) defect rather than injecting SVF cells in saline.

SVF cells and Fibrin Glue

Nucleated adipose-derived cells loaded in a fibrin glue scaffold

Group Type: EXPERIMENTAL

Tisseel Injectable Product

Intervention Type: DRUG

Fibrin glue will provide an inert, biocompatible, viscous substance able to remain within the Rotator Cuff (RC) defect rather than injecting SVF cells in saline.

Stromal Vascular Fraction Cells

Intervention Type: BIOLOGICAL

Stromal Vascular Fraction cells are autologously harvested, processed and reinjected into the affected shoulder.
