COVID-19 studies are our top priority. For all other studies, we recommend commencing the registration process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission as we are experiencing 4 week turn-around time in review of submissions and resubmissions. We currently do not have the capacity to expedite reviews.

Note also there are additional delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Arthroscopic hip surgery entails inserting a small camera into the hip joint to enable the surgeon to view, diagnose and treat hip pathology of the labrum, articular cartilage, or other soft tissues surrounding the joint. The surgeon inserts other instruments through separate incisions to smooth off or repair torn cartilage, trim bone spurs and/or remove inflamed synovial tissue. The procedure takes 30-45 minutes.

Brief summary
Taking 10,000 steps a day is promoted by The Centres of Disease Control and Prevention, and The American College of Sports Medicine to equate to a healthy level of physical activity (Pate et al, 1995). Through the use of wearable activity monitors, this study will objectively quantify the limitation in physical activity that hip labral tear patients subjectively report. The study aims to determine whether hip arthroscopic surgery improves physical activity, pain, and quality of life. Satisfaction with surgery will also be assessed and provide further insight into the efficacy of arthroscopic hip surgery.
