Short summary

This study explored whether blue light could help treat difficult joint implant infections caused by drug-resistant bacteria. A new optical fiber that delivers light evenly was tested in the lab. Blue light reduced bacteria more with higher power and longer exposure. These findings suggest that this fiber could support future light-based treatments for deep surgical infections.
