Is intraarticular sodium hyaluronate injection an alternative treatment in patients with adhesive capsulitis?

The aim of this study was to compare the efficacy of sodium hyaluronate (SH) injection with the most common treatment methods, intraarticular steroid injection and physical therapy modalities in patients with adhesive capsulitis (AC). A total of 95 shoulders of 90 patients were included in the study and were randomized in four groups. The patients were treated with SH injection (group 1), triamsinolone acetonide (group 2) or physical therapy modalities (group 3). Group 4 patients were served as controls. Pain severity, passive ranges of motion and functional considerations were measured before, and 15 days and 3 months after the treatments. In all treatment groups, there were significant improvements at both the 15th day and third month in all parameters (for each, p < 0.001). The passive abduction values on the 15th day was found significantly higher in group 3 when compared with group 1 and controls (for each, p < 0.001). At the third month, the passive abduction values of the groups 2 and 3 were improved when compared with the control group (p < 0.001). Constant score was higher in group 3 on 15th day when compared with group 1. At the third month, all treatment groups were improved significantly compared with control group (p < 0.001). We provided the best results in physical therapy modalities applied group for AC treatment. However, we think that SH injection may be administered as an alternative treatment method.
