Mild Osteoarthritis (OA) Braces and Supports Mild OA knee braces and sleeves for arthritis are typically recommended for patients with mild pain that worsens with activity. They’re affordable, easy to wear, and easy to clean. Patients generally only wear them during activity. These can provide some of the support that you’re looking for, while also reducing pain and swelling. Their compression can also help keep your knee joint warm.
