Nanocarrier system for detecting prosthesis loosening

A recent study has demonstrated that doctors may soon have a tool for identifying orthopedic prostheses that are becoming loose after total joint replacement surgery, the most common reason joint replacements fail. The study shows that a minute molecule designed with novel properties can be used to identify patients who are at risk for failure and potentially deliver drugs to stop this process.
