In patients with a bone deformity of the hip (PFA, dysplasia) progressive damage of the intra-articular structures (labrum, articular cartilage) occurs. In early stages, labrum and chondrolabral junction injury are present. In more advanced stages, extensive full-thickness chondral damage occurring in the weight-bearing area of the joint can be identified. To establish the limit between these two stages recognizing which patients are going to profit from arthroscopy (stabilization of chondral injury, labral repair, and correction FAI) remains a challenge in clinical practice.
