Biomechanical properties of the repaired and non-repaired rat supraspinatus tendon in the acute postoperative period.
RatOtherSprague-DawleyFemalen = 48 ratsSurgicalAt the time of surgical detachment
Model: Surgical detachment of the supraspinatus (rotator cuff) tendon
Both repaired and unrepaired tendons had significantly inferior mechanical properties compared with healthy controls at both 12 and 19 days. Repaired tendons showed significant increases in peak, equilibrium and ultimate stress, modulus and stiffness and significant decreases in cross-sectional are…
