The rotator cuff is a group of four muscles and associated tendons that are absolutely integral for normal shoulder function. They work together to stabilise the shoulder – keep the joint centered – and also help move the shoulder. Full thickness tears of the Rotator Cuff can cause significant pain and weakness. There are various ways of repairing the rotator cuff. When it is repaired arthroscopically (keyhole surgery), surgeons use special bone anchors to suture the torn tendon down to the bone, so that healing can occur. Appropriate placement of these bone anchors in good quality bone is crucial to prevent failure of repair and allow such healing. 

Associate Professor Raniga was involved in an important study that figured out exactly where the best bone for anchor placement in rotator cuff repair surgery is. The application of this knowledge may reduce the risk of rotator cuff repair surgery failing and improve patient outcomes.
