Rotator cuff patches literature review 2012 - fraser taylor
- 1. Patches for Rotator Cuff surgery Fraser Taylor Wrightington Hospital
- 2. Whats the Problem? • Rotator cuff tear is a common problem • Failure rates of repair vary from 10-90% !! • Traditional solutions have focused on improving mechanical factors • Interest now in biological solutions
- 3. Sutures PRP Anchors Patches Stem cells Growth factors single vs double? Mechanical vs Biological
- 4. What do they do • Aim to provide Mechanical Augmentation • or • Tendon replacement / interposition • and • Improve rate and quality of Biologic Healing
- 5. Challenges for a Rotator Cuff Replacement Graft • Scaffold must rapidly attach to the stump of the rotator cuff and surrounding tissues • Attach Firmly to bone • Attract and support appropriate cells Alex Castagna
