Introduction: Frozen shoulder is condition in which there is pain and disability of shoulder joint mostly due to contraction of rotator interval capsular ligaments. Hydrodilation is procedure to dilate the contracted capsule using normal saline and local anaesthetic agent while corticosteroid therapy depicts injection of Triamcelone acetate into joint capsule to reduce inflammation and adhesions thereby reducing pain and disability.Objective: Objective of study is to compare effects of Hydrodilatation versus corticosteroids alone in intra articular shoulder joint on mobility of joint and pain in primary idiopathic frozen shoulder.Materials and Methods: 50 patients were taken in our study out of which Maximum patients are in the age group of 40-50 years i.e., 20 patients (40%) followed by 50-60 year age group i.e., 19 patients (38%), There are 31 (62%) male and 19 (38%) females in our study, Right side is more Commonly involved 33 (66%) and left side involved in 17 (34%) patients, In Corticosteroids group, at Presentation mean abduction was 21% which was improved to 61%, external rotation in neutral position was 18% which improved to 89%, external rotation in abduction was 20% which improved to 83%, In Hydrodilatation group, at Presentation mean abduction was 20% which was improved to 60%, external rotation in neutral position was 18% which improved to 86%, external rotation in abduction was 22% which improved to 82%, Average SPADI and ASES score not showing any significant difference in outcome at 1 year follow up between Hydrodilatation and corticosteroids group of patients.Conclusion: In this study, we investigated treatment effects in patients with adhesive capsulitis treated with either intra articular corticosteroid or with hydrodilatation procedure. Shoulder of the dominant hand (right side) is more commonly involved. No significant difference in the outcome as assessed with SPADI and ASES was found between both groups at 1 month, 6 month and 1 year follow up. In both groups there was significant improvement in range of motion & pain.
