Introduction: Frozen shoulder also known as adhesive capsulitis is a condition characterized by pain and loss of motion of the shoulder joint. Several modalities of treatment have been devised for the management of this condition. The purpose of the present study was to evaluate the effectiveness of intra-articular steroid injection in the management of frozen shoulder. Materials and Methods: This was a prospective observational study conducted on 40 patients of either sex with an average age of 56.65 years presenting to the Government Hospital, Pakherpora, J&K, India between January 2018 and November 2019, with a diagnosis of frozen shoulder. All the patients were administered intra-articular steroid injections into the shoulder joint. The patients were followed up for a period of 6 months. The results were analysed through the assessment of visual analog scale (VAS) and disability of arm shoulder and hand (DASH) score. Results: Majority of the patients had significant relief with this method. The VAS and DASH score improved from the pre-treatment values of 8.92 and 78.62 to 2.55 and 27.56 respectively, which was found to be statistically significant (p<0.001). Conclusion: The results of our study demonstrate that the intra-articular steroid injection is a safe and effective treatment modality for frozen shoulder.
