Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Osteoarthritis (OA) is the most common form of arthritis. It can cause pain, swelling, and reduced motion in the joints. That can reduce quality of life.

OA can occur in any joint, but usually affects the hands, knees, hips or spine.

The purpose of this study is to find out if doctors might be able to use 2% PENNSAID gel to treat OA in the knee.
