Tissue energy imaging to guide treatment for damaged cartilage
Using redox balance to guide surgical and therapeutic decisions for cartilage disease
This project tests a camera-like imaging tool that reads cartilage's natural energy signals to help doctors choose better treatments for people with early cartilage damage or osteoarthritis.

What this research studies
Researchers are building a small, label-free imaging device called optical redox imaging (ORI) that captures the natural glow from molecules in cartilage to measure metabolic balance and mitochondrial health. They will test the device on cartilage samples and during routine arthroscopic procedures to see whether ORI signals match early damage and predict tissue responses to mitochondrial-targeted therapies. The program combines laboratory studies, device development, and pilot clinical imaging to refine measurements that could be used in real time in the operating room. The approach does not require dyes and aims to give immediate feedback that can inform surgical or medical decisions.
Who could benefit from this research
Good fit: Ideal candidates are people with early cartilage injury or early-stage osteoarthritis, especially those undergoing arthroscopy or other joint procedures.
Not a fit: Patients with advanced, end-stage osteoarthritis where cartilage is largely lost, or people not having joint procedures, are less likely to benefit from this imaging approach.
Why it matters
Potential benefit: If successful, the tool could help clinicians detect early cartilage damage and choose treatments that slow or prevent progression to disabling osteoarthritis.
How similar studies have performed: ORI has shown promise in cancer organoid studies and preliminary lab data suggest cartilage metabolic signals are informative, but applying ORI clinically for osteoarthritis is a novel approach.
