Hip arthroscopy is increasingly being used to treat the problems arising from borderline dysplasia (borderline hip dysplasia). This question, however, remains controversial and the literature offers insufficient evidence.
A new study published in “American Journal of Sports Medicine” sought to assess the contribution of hip arthroscopy for femoroacetabular impingement (FAI) to the problems resulting from borderline hip dysplasia.
Data were collected from consecutive patients who underwent primary hip arthroscopy with capsular closure, operated on for the treatment of femoroacetabular impingement between 2012 and 2014. Their data were collected and analysed prospectively. Patients with borderline dysplasia were taken to be those with a Wiberg angle or centre-edge angle (lateral center-edge angle - LCEA) of 20 to 25°, while normal patients were taken to be those with angles of 25 to 40°. Follow-up data on these patients were collected for five years postoperatively.
The authors concluded that the rates of a successful clinical outcome five years after arthroscopic treatment with capsular closure for femoroacetabular impingement were not significantly different between patients with borderline dysplasia and those without dysplasia. The factors predisposing to a good postoperative outcome were adequate physical activity, running as a sport, female sex, and a large LCEA in patients with borderline dysplasia.
