Treatment of Irreparable Rotator Cuff Tears: Superior Capsular Reconstruction with Fascia Lata Allograft.

 The objective of the present study was to evaluate the efficacy and safety of superior capsular reconstruction (SCR) using fascia lata allograft.  A prospective case series of 15 patients with irreparable supraspinatus tear who underwent SCR using fascia lata allograft. The American Shoulder and Elbow Surgeons (ASES) scale at 12 months after surgery was the primary outcome. The University of California Los Angeles (UCLA), Constant-Murley, and Single Assessment Numeric Evaluation (SANE) scales, in addition to the range of motion, were secondary outcomes. Radiological parameters were also evaluated by simple radiographs and magnetic resonance imaging (MRI).  Fifteen patients completed 12 months of postoperative follow-up. The ASES score increased from 34.0 to 73.0 (  = 0.005). The UCLA, Constant-Murley, and SANE scales also showed statistically significant differences (  = 0.001;  = 0.005; and  = 0.046). In the evaluation of range of motion, there was improvement in elevation and in external rotation (95 to 140°,  = 0.003; 30 to 60°,  = 0.007). Six patients (40%) had complete graft healing. The clinical outcomes were significantly higher in the patients who presented graft healing.  Superior capsular reconstruction using a fascia lata allograft is a safe and effective procedure in short follow-up.
