ClinConnect Summary

In this study, we investigate the use of 3D models during pre and intra-operative planning could improve the success of hip arthroscopy and reduce the incidence of revision cases. By adding an adjunct to the common suite of pre-operative imaging modalities (X-ray, MRI and CT), we can change the surgeon's understanding of each patient's individual morphology with a tactile physical model. This study will compare the success of hip arthroscopy in patients with or without 3D printed models (in addition to traditional pre-operative imaging).

This will be a single-center, blinded observer, rand...
