Reversal of Pseudoparalysis in Posterosuperior Irreparable Rotator Cuff Tears: Superior Capsular Reconstruction vs Latissimus Dorsi Tendon Transfer vs Lower Trapezius Tendon Transfer

Background: Superior capsular reconstruction (SCR), latissimus dorsi tendon transfer (LDT), and lower trapezius tendon transfer (LTT) can be used to manage posterosuperior irreparable rotator cuff tears (PSIRTCs) with nonarthritic pseudoparalysis. However, no study has compared SCR, LDT, and LTT as joint-preserving treatment options for PSIRCTs with pseudoparalysis. Purpose/Hypothesis: This study aimed to compare the clinical and radiologic outcomes of SCR, LDT, and LTT in PSIRCTs with nonarthritic pseudoparalysis. It was hypothesized that LTT would be the most effective joint-preserving treatment option for PSIRCTs with pseudoparalysis. Study Design: Retrospective case-control study; Level of evidence, 3. Methods: A retrospective review was conducted of 59 patients with PSIRCTs who had nonarthritic pseudoparalysis and underwent surgical treatment between January 2014 and December 2020. The cohorts consisted of 19 patients who underwent SCR, 16 patients who underwent LDT, and 20 patients who underwent LTT. Pseudoparalysis was defined as forward elevation (FE) remaining
