RESUMO
Background: Adhesive capsulitis of the shoulder is a painful and debilitating condition. While the majority of patients improve with conservative treatment, those who do not improve require surgery such as arthroscopic capsular release (ACR) for symptom relief. However, there is limited literature regarding the optimal timeframe to proceed with surgery. Methods: This retrospective cohort evaluated 134 Hispanic patients who underwent ACR for the treatment of adhesive capsulitis. Patients were divided into an early and a delayed treatment group that included all patients. Patients were then divided into diabetic and idiopathic subgroups. Early vs. delayed treatment outcomes (forward flexion, external rotation, Visual Analog Scale pain scores, and recurrence requiring reoperation) were assessed in all patients and in each subgroup. Results: No statistically significant differences were found between the early and delayed release groups in postoperative forward flexion, external rotation, pain intensity scores, and recurrence requiring reoperation at 1 month, 3 months, and 6 months of follow-up in the all-patient group. In the idiopathic frozen shoulder subgroup, no significant differences were observed in postoperative forward flexion, external rotation, pain intensity scores, and recurrence requiring reoperation at 1 month, 3 months, and 6 months of follow-up. In the diabetic frozen shoulder subgroup, no significant differences were observed in postoperative forward flexion, external rotation, pain intensity scores, and recurrence requiring reoperation at 1 month and 6 months of follow-up visits. Conclusions: There was no difference in outcomes following ACR for adhesive capsulitis between patients who underwent early release vs. delayed release. There were no significant differences in outcomes between early and delayed arthroscopic release in patients with a history of diabetes mellitus.
