The Acromioclavicular Joint (ACJ) is commonly injured in contact and overhead athletes. The treatment of ACJ injuries is controversial. Furthermore, there is no reliable and accurate way of assessing the severity of these injuries. 

Associate Professor Raniga and his colleagues developed and tested a novel way of reliably and accurately assessing these injuries. The application of this method of assessment allows surgeons to make better decisions about who needs an operation and who doesn’t. Good decision making is integral to good patient outcomes.
