Comparison of intra articular NSAID (ketorolac) injection versus hyaluronic acid injection for the mean decrease of pain score (according to UCLA shoulder rating scale) in the management of adhesive capsulitis

Abstract

Adhesive capsulitis is painful condition, associated with gradual loss of active and passive shoulder motion that has a disabling capability. In this study we compared the short term outcome by measuring the mean decrease of pain in adhesive capsulitis using University of California Los-Angeles (UCLA) shoulder rating scale after intra-articular Non-Steroidal Anti Inflammatory Drug (NSAID) Ketorolac and Hyaluronic acid injection. This Randomized controlled trial was carried out using non probability consecutive sampling technique from 1st November 2015 to 30th April 2016. Total 160 patients with adhesive capsulitis for six months’ age between 18 to 70 years were taken and randomly divided into two equal groups by computer allocation method. The 80 patients in Group A received Intra-articular (NSAID) Ketorolac injection while patients in Group B were given Intra-articular Hyaluronic acid. Pain score for both the groups were recorded using UCLA shoulder rating scale before treatment and then at follow up after a period of 4 weeks. Out of total 160 cases, 47.5% (n=38) in Group A and 45% (n=36) in Group B were male whereas 52.5% (n=42) in Group A and 55% (n=44) in Group B were females. Most commonly affected age group with 40% (n=32) participants was aged between 51 - 60 years. Mean age of Group A was 37.87±1.027 and in Group B was 45.37±5.743. Interestingly 60% (n=48) of Group A and 55% (n=44) of Group B had involvement of the right shoulder. Pre-treatment UCLA pain score was calculated to be 14.90±4.969 in Group-A and 15.16±5.578 in Group-B. Final post treatment UCLA score was 26.67±2.331 in Group A and 21.72±3.838 in Group B. The mean decrease of pain in Adhesive capsulitis using UCLA rating scale was significantly better in NSAID group as compared to Hyaluronic acid group.
