Biomechanical evaluation of a new technique for rotator cuff repair.
BACKGROUND In recent studies, investigators have used a cyclic loading model to investigate the efficacy of rotator cuff fixation modalities. HYPOTHESIS A bioabsorbable poly-D-lactic acid screw and toothed washer implant will provide more stable fixation of rotator cuff repairs than standard suture anchor techniques. STUDY DESIGN Controlled laboratory study. METHODS Forty bovine shoulders...
متن کاملIcariin Promotes Tendon-Bone Healing during Repair of Rotator Cuff Tears: A Biomechanical and Histological Study
To investigate whether the systematic administration of icariin (ICA) promotes tendon-bone healing after rotator cuff reconstruction in vivo, a total of 64 male Sprague Dawley rats were used in a rotator cuff injury model and underwent rotator cuff reconstruction (bone tunnel suture fixation). Rats from the ICA group (n = 32) were gavage-fed daily with ICA at 0.125 mg/g, while rats in the contr...
متن کاملBiomechanical performance of rotator cuff repairs with humeral rotation: a new rotator cuff repair failure model.
BACKGROUND Traditional biomechanical evaluations of rotator cuff repair techniques employ cyclic loading of the supraspinatus tendon in an isolated medial direction. PURPOSE This study was conducted to evaluate 2 different rotator cuff repair techniques that are currently the subject of debate with cyclic loading and with internal and external humeral rotation to better simulate postoperative...
متن کاملArthroscopic Rotator Cuff Repair: A Biomechanical Comparison of Single Row and Suture-Bridge Tendon Repair Constructs
INTRODUCTION: Rotator cuff tears are a very common source of pain and loss of function of the shoulder. As arthroscopic instrumentation and repair techniques have evolved, many studies have demonstrated success in repairing rotator cuff tears using these arthroscopic techniques alone compared with an open repair method. Despite these successful clinical outcomes, both open and arthroscopic rota...
متن کاملTendon trap technique for rotator cuff repair.
Strangulation around cuff tissue is a possible cause of retear after rotator cuff repair. Therefore, tendon healing ideally requires changes in suture tension over the cuff tissue in accord with rotator cuff muscle activity. The authors present a type of fixation that mimics the mechanism of the Chinese finger trap. The devised knot-free tendon trap technique resembles the double-pulley-suture ...
