In degenerative articular disorders, pre-structural cartilage degeneration is important to diagnose, as these patients are most amenable to surgical as well as non-surgical interventions. In Femoroacetabular Impingement, intervention is most appropriately applied to those patients with pre-structural cartilage changes. Hence we sought to determine, via T1ρ, if there are early changes in cartilage proteoglycan content in patients with unilateral symptomatic CAM type FAI, as compared to their asymptomatic CAM type FAI contra-lateral side, normal volunteers, as well as a unique possibly transition group who have CAM deformity but who are asymptomatic.
