Researchers are testing a new mobile technology called OpenCap that uses smartphone videos to measure how your knee moves and functions. This technology is designed to be simpler and more affordable than traditional motion capture equipment. The study aims to see if this smartphone-based approach can help doctors better understand knee health in people with early-stage osteoarthritis.
Currently, doctors rely mainly on X-rays to diagnose knee osteoarthritis, but X-rays often miss early-stage disease in younger patients—exactly when treatment is most likely to help. This trial exists to see if measuring how your knee actually moves (rather than just looking at pictures) could help doctors catch and treat osteoarthritis earlier.

As a participant, you would return for a follow-up assessment where you would perform simple movement activities (like walking or stepping) while researchers film you with smartphones. The OpenCap technology would then analyze those videos to measure how your knee moves. The study involves 47 people total, and you would be asked to complete these movement tests as part of a one-time or limited follow-up visit.
