Overview
Brief Summary
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.
Detailed 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.

Outcomes
Primary Outcomes
Mean score of University California Los Angeles (UCLA) activity assessment
Time Frame: 1 year follow-up time point
Measured on a 1-10 scale: 1) wholly inactive, dependent on others; 2) mostly inactive, restricted to minimal activities of daily living; 3) sometimes participate in mild activities such as walking, limited housework, or shopping; 4) regularly participate in mild activities; 5) sometimes participate in moderate activities such as swimming and unlimited housework or shopping; 6) regularly participate in moderate activities; 7) regularly participate in active events such as bicycling; 8) regularly participate in very active events such as bowling or golf; 9) sometimes participate in impact sports such as jogging, tennis, or skiing, or heavy labor; and 10) regularly participate in impact sports.
Mean score of Hip Disability and Osteoarthritis Outcome (Hoos)
Time Frame: 1 year follow-up time point
Score ranges from 0-100 with higher scores representing better function.
Mean score of Western Ontario and McMaster Universities Arthritis Index (WOMAC)
Time Frame: 1 year follow-up time point
The scores range from 0-4 in 24 different categories that are broken up into three subcategories: pain, stiffness and physical function.
Mean score of the Marx Activity Scale (MARX)
Time Frame: 1 year follow-up time point
Score is measured from 0-4.
