Assessing Initial Functional Outcomes Following Arthroscopic Release for Stiff Shoulder in Periarthritis Shoulder

Abstract

Adhesive capsulitis can manifest as either primary/idiopathic or secondary, often linked to systemic illnesses. Primary adhesive capsulitis is characterized by limited range of motion without underlying systemic or precipitating shoulder conditions and lacks intrinsic pathology. In contrast, secondary frozen shoulder is associated with identifiable intrinsic factors such as diabetes, thyroid disorders, cardiac disease, stroke, prolonged immobilization, trauma, and rotator cuff disease. Our study aims to assess the initial functional outcomes, average recovery duration, and related comorbidities in arthroscopic release for adhesive capsulitis of the shoulder.The study was carried out at the Department of Orthopedics in Saveetha Medical College and Hospital, Thandalam, spanning from June 1, 2022, to June 31, 2023. It comprised 30 patients diagnosed with adhesive capsulitis who met specific criteria. The treatment regimen consisted of Arthroscopic Release followed by intensive physiotherapy and prescribed home exercises. Follow-up appointments were scheduled at regular intervals to track progress, using assessment tools like the UCLA Score and VAS score, and all data were meticulously recorded in a standardized proforma.30 individuals who met specific criteria were diagnosed with adhesive capsulitis. Of these, 12 out of 18 participants were female, and 16 patients experienced more frequent impairments on the left side. The average age of the patients was 65 years, ranging from 57 to 78 years old. Stage 2 was the most common among the approximately 19 patients. Prior to surgery, the UCLA score had a mean of 23, ranging from 18 to 26, while the mean preoperative VAS score was 8, with a range of 7 to 9. Following surgery, significant improvements were observed in the UCLA score, ranging from 26 to 35, and the post-operative VAS score ranged between 2 and 5. In our study, arthroscopic release appears as a safe procedure with favourable postoperative results. This consequently enables early mobilization of the shoulder joint and decreases complication rates.
