Randomized Controlled Trial Multicenter StudySodium hyaluronate for the treatment of chronic shoulder pain associated with glenohumeral osteoarthritis: a multicenter, randomized, double-blind, placebo-controlled trial.
Nonoperative treatments for glenohumeral osteoarthritis (GH-OA) are limited. Intra-articular therapy with sodium hyaluronate (HA) has been effective in treating OA of the knee. Therefore, we sought to evaluate the efficacy and safety of HA in treating chronic pain associated with GH-OA. ⋯ A numeric advantage, but without statistical significance, was found for HA ITT patients with GH-OA. Although data for a subset of HA patients without concomitant pathologies reached statistical significance, additional randomized trials are needed to confirm the clinical implication of this outcome.

Randomized Controlled Trial Comparative StudyA double-blind randomized controlled trial comparing the effects of subacromial injection with corticosteroid versus NSAID in patients with shoulder impingement syndrome.
The objective of this study was to compare the efficacy of subacromial injection of triamcinolone compared to injection of ketorolac in the treatment of external shoulder impingement syndrome. ⋯ In this study, an injection of ketorolac resulted in greater improvements in the UCLA shoulder rating scale than an injection of triamcinolone at 4 weeks follow-up. While both triamcinolone and ketorolac are effective in the treatment of isolated subacromial impingement, ketorolac appears to have equivalent if not superior efficacy; all the while decreasing patient exposure to the potential side-effects of corticosteroids.
