The Acromioclavicular Joint (ACJ) is commonly injured in contact and overhead athletes. The treatment of ACJ injuries is controversial. Associate Professor Raniga was involved in developing a novel surgical technique of restoring stability to the injured ACJ. This technique restores stability in both the vertical and horizontal directions. Most current operations only restore stability in the vertical direction and ignore the horizontal instability with poor results. This novel BiPOD technique, which is carried out arthroscopically (keyhole surgery) addresses instability of the ACJ in the vertical and horizontal planes with good patient outcomes.
