Welcome to the Osteoarthritis (OA) Risk Calculator

This risk calculator uses demographic information to estimate your chance of developing knee osteoarthritis or having a total knee replacement if you have not previously been diagnosed with knee osteoarthritis.

The calculator also allows you to see how different risk factors affect your chance of developing knee osteoarthritis or having a total knee replacement, and it compares your chance to that of the average American.

There are two different risk calculators: one for people who have not been diagnosed with knee osteoarthritis, and one for those who have been diagnosed with knee osteoarthritis.
