Figure 4From: Postnatal development of collagen structure in ovine articular cartilageOrientation index. (a) Mean orientation index (solid) ± standard deviation (dashed) as a function of age. (b) Mean orientation index as a function of age for the caudal site (solid), distal site (dashed) and rostral site (dotted). The model predicts significant differences for: 'x' - rostral site > caudal site and '+' - distal site > caudal site.Back to article page
