Abstract Summary
The effects of hip arthroscopy on hip joint mechanics and cartilage health in patients with femoroacetabular impingement syndrome (FAIS) are not well understood. In our exploratory study, patients with FAIS exhibited abnormal hip joint mechanics both prior to and after hip arthroscopy, when compared to controls. Changes in hip joint loading predicted changes in cartilage T2 values (worse collagen structure) in patients with FAIS. Our study results suggest that hip joint mechanics remain altered 7 months after hip arthroscopy and is associated with alterations in cartilage composition.
