THE PROBLEM

Total knee arthroplasty (TKA) is one of the most common surgical procedures in the United States. The leading cause of revision is periprosthetic bacterial infection (PPI), which occurs in up to 3% of all TKAs. At a cost of over $50,000 per revision, the total annual cost of PPI is nearly $400 million. Current methods of diagnosing infection are invasive, unreliable, and can only detect later stages of infection, by which time revision is inevitable.

THE TEAM

We are a small team of biomedical engineers committed to finding a way to detect

periprosthetic infection while antibiotics are still a viable treatment option. We are working to perfect our solution and aim to bring it to market in the next few years.

THE SOLUTION

We have designed a novel solution that detects infection in vivo and alerts the patient in real time. Our device measures changes in the optical properties of synovial fluid caused by the immune response to infection, and wirelessly reports this data. This is a truly unique approach; ours will be the first orthopedic implant with diagnostic functionality.

With our proposed solution, only one TKA will be necessary.
