Intra-articular injection of high molecular weight hyaluronate significantly improved WOMAC pain, stiffness, and physical functioning at 26 weeks of follow-up for study subjects with glenohumeral osteoarthritis. Subjects were treated with one injection per week for 3 weeks of high molecular weight hyaluronate and followed-up after treatment for 26 weeks. Data represent mean change from baseline (week 1) ± standard deviation after treatment with high molecular weight hyaluronate over 26 weeks of follow-up in (A) WOMAC pain scores, (B) WOMAC stiffness scores, and (C) WOMAC physical functioning scores.
