The longitudinal effects of Slipped Capital Femoral Epiphysis (SCFE) on hip cartilage integrity and hip function are poorly understood. In this study, 44 hips were evaluated with delayed Gadolinium-enhanced MRI of cartilage (dGEMRIC) in average 11 years after SCFE. A low dGEMRIC index was detected in SCFE hips compared to unaffected hips, with gradually lower dGEMRIC index anteriorly in the hip joint. Furthermore, a low dGEMRIC index correlated both with impaired hip function and femuroacetabular impingement (FAI), which further strengthens the theory of FAI as a mediator of osteoarthritis after SCFE.
