Dye test could help surgeons spot shoulder Re-Tear risk during surgery

Summary

This trial tests different doses of a fluorescent dye called IC-Green in people having arthroscopic rotator cuff repair. The dye binds to blood proteins and makes blood vessels visible under a special camera. The goal is to find the best dose for seeing blood flow in the torn tendon during surgery. Better visibility of blood flow might one day help surgeons predict and prevent re-tears, but this study only focuses on finding the right dose.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Indocyanine Green (ICG) dye
What this could lead to
If successful, this could help surgeons see blood flow in the shoulder during rotator cuff repair, potentially predicting and preventing re-tears.
What could go wrong
This is a very early, small study focused only on finding the best dye dose. It does not test whether seeing blood flow actually prevents re-tears, so the real benefit remains unknown.
