Randomized Controlled Trial Multicenter Study Comparative StudyDoes hyaluronate injection work in shoulder disease in early stage? A multicenter, randomized, single blind and open comparative clinical study.
This study assessed the hypothesis that injection of high-molecular weight hyaluronate in the treatment of subacromial impingement syndrome is effective and safe, compared with corticosteroid injection in the shoulder joint. ⋯ A subacromial hyaluronate injection to treat impingement syndrome produces similar pain and functional improvement to corticosteroid at a short-term follow-up.
