Cartilage plates and subregions used as outcome measures in this study. (a) Inferior view of the weight-bearing (central) part of the medial (cMF) and lateral femoral condyle (cLF). ccMF = central third of cMF (icMF and ecMF = internal and external third of cMF, respectively). (b) Posterior view of the femorotibial joint. MFTC = cMF + MT; cMFTC = ccMF + cMT. (c) Superior view of the medial (MT) and lateraltibia (LT). cMT = central part of MT (iMT, eMT, aMT, and pMT = internal, external, anterior, and posterior parts of MT, respectively).
