Fascia Lata Autograft Versus Human Dermal Allograft in Arthroscopic Superior Capsular Reconstruction for Irreparable Rotator Cuff Tears: A Systematic Review of Clinical Outcomes

摘要

Purpose: To determine the clinical outcomes of arthroscopic superior capsular reconstruction (AS CR) using either fascia lata autograft or human dermal allograft for irreparable rotator cuff tears (IRCTs). Methods: A systematic review was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines by searching the MEDLINE, Embase, and Cochrane Library databases through January 31, 2019. The inclusion criteria were as follows: 5 or more consecutive patients who underwent ASCR for IRCTs; clinical outcome measures reported at a minimum follow-up of 12 months; and magnetic resonance imaging assessment at a minimum follow-up of 6 months. The methodologic quality was evaluated using the Methodological Index for Non-randomized Studies (MINORS). A narrative synthesis of data was performed. Mean outcome improvements were compared with minimal clinically important differences. Results: We identified 7 eligible studies that included 344 shoulders in 338 patients who underwent ASCR for IRCTs (all Level IV studies). The mean MINORS score was 12.3 +/- 1.60. Of the 7 studies, 5 had a high risk of bias (MINORS score <= 12): 2 studies using only fascia lata autograft and 3 studies using only human dermal allograft. The mean age of patients ranged from 59.4 to 66.9 years. The mean follow-up time ranged from 12 to 48 months. All studies reported statistically significant and clinically important mean improvements in active elevation (range of means, 28 degrees-56 degrees), the Constant score (range of means, 12-47.1 points), or the American Shoulder and Elbow Surgeons score (range of means, 29.3-56 points). In total, 218 shoulders underwent postoperative magnetic resonance imaging. The graft tear rate reported in studies using fascia lata autograft (181 shoulders) ranged from 5% to 32%, whereas the values reported in studies using human dermal allograft (37 shoulders) ranged from 20% to 75%. Conclusions: ASCR using either fascia lata autograft or human dermal allograft leads to significant and clinically important improvements in clinical outcomes in IRCT patients at 12 months or later.
