Arthroscopic Superior Capsular Reconstruction With Acellular Dermal Allograft for the Treatment of Massive Irreparable Rotator Cuff Tears: Short-Term Clinical Outcomes and the Radiographic Parameter of Superior Capsular Distance.

Purpose: This outcome analysis presents 88 consecutive shoulders presenting with irreparable rotator cuff tears that we treated with arthroscopic superior capsular reconstruction (SCR) using an acellular dermal allograft. We also present the concept of superior capsular distance to quantitatively measure the decreased distance present upon restoration of superior capsular integrity.

Methods: A retrospective review was conducted of patients treated with arthroscopic SCR with a minimum 12-month follow-up.
