Conditions such as femoroacetabular impingement (FAI) characterized by an anatomic deformity at the femoral head-neck junction, is known to affect the pathogenesis of hip osteoarthritis (OA) and have been identified as pertinent causes of premature OA of the hip joint in young and middle-aged patients. Early detection of cartilage degeneration could help identify patients with hip pain who may benefit from early intervention The objective of this study was to perform a sub-regional analysis of cartilage magnetic resonance (MR) relaxation times (T1ρ and T2) measurements in the hip joint for early assessment of cartilage defects in patients with FAI.
