Hello, and welcome to Mayo Connect. We are a community of people living with a variety of health conditions and diseases, who try to help and support each other on our journeys. We are not doctors, so we cannot give medical advice, but we can share our experiences. I have not had my knee replaced, but had multiple hip replacement surgeries due to metallosis from the first implants used.

In your situation, after 2 unsuccessful implants and your desire for a new alternative, you might want to contact a larger multidisciplinary facility like May Clinics or a University hospital near you to discuss newer options. You could also search on line for "new techniques in knee replacement" or similar, and just follow where it leads, concentrating on articles published by NIH, or Orthopedic professional groups.

Does this give you a starting point?
