Cline K, Tibone JE, Ihn H, et al. - The present study was conducted to biomechanically define superior capsule reconstruction (SCR) applying fascia lata allograft, double layer dermal allograft, and single layer dermal allograft for a clinically relevant massive irreparable rotator cuff tear involving the entire supraspinatus and 50% of the infraspinatus tendons. Researchers tested eight cadaveric specimens in 0, 30, and 60 degrees of abduction for intact, massive rotator cuff tear, SCR using fascia lata, SCR using double-layer dermis, and SCR using single layer dermis. They assessed superior translation and subacromial contact pressure. They performed statistical analysis applying repeated measures ANOVA or paired t-test with p< 0.05. According to the findings, all three graft types may restore superior translation and subacromial contact pressure depending on the glenohumeral abduction angle, fascia lata and double layer dermis may be more effective than single layer dermis for SCR tensioned at 20 degrees of glenohumeral abduction.
