A Comparison of the Treatment Outcomes With and Without the Use of Intra-articular Corticosteroids for Frozen Shoulder Manipulation

Background Manipulation under anesthesia is known to be an effective treatment method for a frozen shoulder. However, this process is painful and causes difficulty in early physiotherapy. Intra-articular corticosteroids may relieve pain after manipulation. This study compared patients who underwent manipulation under anesthesia with those who only underwent physiotherapy and those who received intra-articular corticosteroid administration and physiotherapy. Methodology A total of 33 patients presenting with frozen shoulders were included in this study. Those who underwent manipulation after anesthesia were determined as group 1 (16 patients) and those who received intra-articular corticosteroids in addition to manipulation under anesthesia were determined as group 2 (17 patients). Pain was evaluated using the Visual Analog Scale (VAS) scores. Functional outcomes were assessed using the University of California-Los Angeles (UCLA) scores and shoulder range of motion (ROM). Results VAS and UCLA scores of both groups were similar at 12 weeks and six months. ROM improved significantly after manipulation in both group 1 and group 2 (p < 0.05). There was no significant difference between the ROM in the two groups after manipulation and physiotherapy. Only the external rotation ROM value was better in group 2 (p = 0.032) Conclusions Physiotherapy after manipulation is a successful treatment method for frozen shoulder patients. It reduces pain in the early period compared to patients who are not administered intra-articular corticosteroids. However, it has no functional superiority.
