Summary

This study compared a 3D-printed surgical guide (Corin OPS™) to standard methods for placing the hip socket during total hip replacement. The goal was to see if the guide leads to more accurate implant positioning, which could reduce the need for early revision surgery. 54 adults having a first hip replacement took part. The study measured accuracy using post-surgery CT scans.
