Efficacy of Combined Intra-Articular Hyaluronic Acid and Ketorolac Versus Ketorolac Alone in the Treatment of Adhesive Capsulitis: A Randomized Controlled Trial
In Brief
A Phase 3 clinical trial evaluating Intra-articular Hyaluronic Acid and Ketorolac and Intra-articular Ketorolac for Adhesive Capsulitis of the Shoulder. Completed, enrolled 56 participants across 1 site.
Detailed Summary
This randomized, double-blind trial compared a single intra-articular injection of moderate-molecular-weight hyaluronic acid (HA) plus ketorolac with ketorolac alone in patients with adhesive capsulitis. Fifty-six participants were randomized into two equal groups and followed for 24 weeks. The primary outcome was shoulder function measured by the Thai Shoulder Pain and Disability Index (SPADI). Secondary outcomes included pain (VAS), passive range of motion (PROM), analgesic use, and adverse events. Both groups showed significant improvement in pain and function with no between-group difference in SPADI or VAS. The HA+ketorolac group demonstrated small but significant gains in external rotation and adduction. Both treatments were safe and well tolerated.

Interventions
Single intra-articular injection containing 2 mL moderate-molecular-weight hyaluronic acid (20 mg/2 mL), 1 mL ketorolac (30 mg/mL), and 2 mL lidocaine (10 mg/mL), total volume 5 mL. Administered under aseptic technique (ultrasound-guided or landmark-based) followed by standardized rehabilitation program.
