Add RecipientIf you suffer from osteoarthritis in your knees, or if you sleep on your side and often wake with morning knee pain, slide on FootSmart Nighttime Osteoarthritis Knee Sleeve at bedtime & ease the pain of arthritic knees. While you sleep, a soft donut-shaped pad stitched into the sleeve disperses pressure on sensitive areas over the medial knee, holding the knees in proper alignment throughout the night. As a result, you awake with less pain and inflammation. The cushiony brace stabilizes the knee joint, reducing pain and inflammation. Determine size by measuring 6 inches above the kneecap.
