About

The study will assess the outcomes of patients treated with concomitant hip arthroscopy at the time of periacetabular osteotomy (PAO) for patients with hip dysplasia compared with patients treated with PAO alone.

Full description

There are currently no absolute indications for intraarticular assessment at the time of periacetabular osteotomy (PAO). Based on investigators' review of the literature and experience, patients who may benefit from intraarticular assessment are those with radiographic or MRI evidence of damage where an intraarticular inspection may help in determining whether a PAO is a reasonable procedure, those with mechanical symptoms likely related to labral pathology, round ligament or cartilage problems and those with hip dysplasia and cam deformities with limited range of motion that may benefit from femoral head neck junction osteochondroplasty. However, despite these relative indications today there is no clear evidence to suggest that these patients will do better than those that do not have intraarticular work done. Hence, the objective of this project is to determine whether intraarticular work at the time of PAO surgery leads to improved pain and function when compared to patients that do not undergo intraarticular work at the time of PAO.
