Abstract
Thirtyfour volunteers mean age 246 ± 27 years with no history or clinical findings indicative of any knee joint disease were enrolled The protocol included a doubleecho steadystate DESS sequence for morphological cartilage evaluation and a gradientecho multiecho sequence for T2 assessment Bulk and zonal T2 values were assessed in eight regions posterior lateral femoral condyle central lateral femoral condyle trochlea patella lateral tibial plateau posterior medial femoral condyle central medial femoral condyle and medial tibial plateau Statistical evaluation comprised a twotailed t test and a oneway analysis of variance to identify zonal and regional differencesT2 mapping revealed higher T2 values in the superficial zone in all regions P values ≤ 0001 except for the posterior medial femur condyle P = 0087 and substantial regional differences demonstrating superior values in trochlear cartilage intermediate values in patellar and central femoral condylar cartilage and low T2 values in posterior femoral condylar cartilage and tibial plateau cartilage
