Arthroscopic treatment of adhesive capsulitis

Although conservative management with or without manipulation performed with the patient under anesthesia is the generally accepted treatment strategy for adhesive capsulitis, considerable interest is being shown in arthroscopic surgical procedures for this disorder. This study reviews the outcome of patients who underwent an arthroscopic release of the inferior capsule, reproducing in a controlled fashion the traumatic disruption of the inferior capsule commonly caused by manipulation with the patient under anesthesia. The outcome of 24 patients (26 shoulders) was assessed with an average follow-up of 13.5 months. A total of 88% of patients were very satisfied with the procedure, and no operative complications occurred. A return to normal or near normal shoulder function in 76% or more of the study group for forward flexion, abduction, and external rotation was demonstrated. A total of 50% of patients still had some restriction in internal rotation. The Constant Scoring system, also used to assess clinical shoulder function, revealed 87% of patients had achieved an excellent or good result when compared with the contralateral normal shoulder score. Our results suggest that arthroscopic capsular release is a safe and effective treatment for adhesive capsulitis, with patterns of recovery that compare favorably to other treatment modalities.
