Arthroscopic superior capsular reconstruction versus latissimus dorsi transfer for irreparable rotator cuff lesions: a systematic review.

INTRODUCTION: The present systematic review compared arthroscopic superior capsular reconstruction (ASCR) and latissimus dorsi transfer (ALDT) for the management of massive irreparable rotator cuff lesions. SOURCES OF DATA: We performed a systematic review searching the literature on Medline, Cochrane and Scopus databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. AREAS OF AGREEMENT: We included a total of 20 articles, 10 on ASCR and 10 on ALDT (12 retrospective and 8 prospective studies), all published between 2013 and 2019. AREAS OF CONTROVERSY: ASCR and ALDT are technical demanding procedures. When compared to each other, they do not produce significantly different improvements in clinical outcome. GROWING POINTS: Both ASCR and ALDT are valid options for surgical management of MIRCLs. Although ALDT has shown a greater complication rate and a less improvement in acromion-humeral distance, its clinical outcomes overlap those obtained with ASCR. AREAS TIMELY FOR DEVELOPING RESEARCH: Further comparative prospective and retrospective studies with longer follow-up could confirm which surgical procedure can lead to better outcomes with a lower complication rate.
