Trial Summary

What is the purpose of this trial?This trial uses a tiny camera to look inside the knee without full anesthesia. It targets patients who need accurate diagnosis for knee replacement surgery. The camera helps doctors see the inside of the knee clearly, guiding them to choose the right type of surgery.

Candidates should have unclear x-rays that don't clearly show if they need partial or total knee replacement, can understand English, and give informed consent.
