Video Summary

This research explores hip micro-instability, characterized by abnormal femur-acetabulum motion potentially leading to cartilage overload and osteoarthritis. The study focused on patients with femoroacetabular impingement (FAI) and labral tears, excluding those with tissue laxity or acetabular dysplasia. Investigating the diagnostic value of the hip dial test, researchers found it highly specific (96.9%) in patients reporting instability and having capsular insufficiency during surgery. The study highlights that FAI alone may cause micro-instability and suggests the hip dial test as a useful preoperative tool to guide capsule treatment decisions during hip arthroscopy.
