DANISH HIP ARTHROSCOPY REGISTRY: PREDICTORS OF OUTCOMES IN PATIENTS WITH FEMOROACETABULAR IMPINGEMENT

BACKGROUND & OBJECTIVE

Hip arthroscopy is commonly performed on people with femoroacetabular impingement (FAI) and the rates of hip arthroscopy surgery for this condition are increasing. The authors of this study aimed to determine whether certain pre-operative factors predicted whether or not someone with FAI would have a poor outcome following hip arthroscopy surgery, by using a large national surgery registry. In particular, they were interested in knowing whether someone’s age, sex or extent of cartilage damage affected their outcomes from the surgery.

METHODS

The authors used the Danish hip arthroscopy registry to collect questionnaire information from 1835 patients with FAI over a 3-year period (2012-2015). There were 2054 operations in total as some patients had more than one hip arthroscopy during this time period (11% of the patients had surgery on both hips). The patients and the surgeons used an online data collection system to complete the questionnaires. Patients completed the HAGOS questionnaire before their surgery, and then again 1-year and 2-years after the surgery.

RESULTS

Over the 3-year period of the study, 53% of the patients were female, and the average age of the patients was 38 years. The patients’ ages ranged from 9 - 79 years. Almost half of the patients were aged over
