Forty-three patients with a diagnosis of primary or secondary frozen should
er who had symptoms for an average of 12 months and failed conservative tre
atment of at least 12 weeks of physical therapy, were treated with an arthr
osopic capsular release. Oon completion of standard shoulder arthroscopy, i
ntra-articular cautery wets used to completely divide the anterior-inferior
capsule, the intraarticular portion of the subscapularis tendon, and the m
iddle glenohumeral, the superior glenohumeral, and the coracohumeral ligame
nts. The subacromial space was inspected in all patients. Eighteen patients
had extensive subacromial fibrosis that required debridement. Subacromial
decompression was reserved for patients with evidence of an acromial spur s
een at the time of arthroscopy. Postoperatively, all patients showed substa
ntial gains in shoulder range of motion, as well as diminished shoulder pai
n. Thirty-five patients completed a telephone survey at an average of 22 mo
nths after surgery. The average modified shoulder score was 19 (scale 13 to
65), with 83% of patients indicating that their shoulder was normal or cau
sed only mild symptoms. In conclusion, the authors believe that arthroscopi
c capsular release is an effective and safe alternative to manipulation in
patients with a recalcitrant frozen shoulder.
