Abstract

Background: Superior capsule reconstruction (SCR) has shown promising outcomes in its initial description, but lacks additional reports analyzing outcomes. This study analyzes early outcomes of SCRs in patients with massive irreparable rotator cuff tears.

Methods: A retrospective analysis of all SCRs at our institution from January 1, 2015, to August 31, 2017, was performed with a minimum 6-months follow-up. A total of 34 patients were included with a mean age of 60 years. SCR was performed by 1 of 6 fellowship trained surgeons.

Results: At an average follow-up of 12 months, 22 patients were identified as failures after modified Neer classification. Furthermore, 8 of these patients have undergone a reoperation, whereas an additional 14 patients were considered clinical failures experiencing continued pain and a lack of shoulder function. Of note, 2 of the 3 patients with a subscapularis tear had a failure. In addition, revision cases, female gender, increased fatty infiltration in the infraspinatus and low surgeon volume were associated with a higher rate of failure. There was no significant improvement in range of motion or functional scores.

Conclusion: SCR performed for large-to-massive irreparable rotator cuff tears has a high rate of persistent pain and poor function leading to clinical failure in 65% of patients. Risk factors predicting clinical failure included revision cases, female gender, increased Goutallier fatty infiltration of the infraspinatus, and low surgeon volume (n ≤ 10).
