Figure Lengend Snippet: ( A ) 3D-printed python tooth–inspired device is placed at the native attachment site. ( B ) Schematic biomechanical testing setup for human cadaver rotator cuff tendons repaired with double-row suture only or device and suture. ( C ) Representative force-displacement curves for biomechanical tests of cadaver supraspinatus repairs with and without the device. ( D to F ) Mechanical evaluation of the device compared to the state-of-the-art rotator cuff repair. N = 5 biologic replicates per group. P values were determined using a two-tailed, paired Student’s t test (* P < 0.05). The device significantly increased the maximum force and energy absorption of the repaired rotator cuff.
Article Snippet: To assess the device in a clinically relevant rotator cuff repair setting, paired human cadaver rotator cuff samples were used (Anatomic Gift Foundation Inc., Hanover, MD).
