Abstract:
Microscopic features of acetabular articular cartilage showed that it was entirely cartilaginous in prenatal stage of Group-I since articular cartilage was not yet differentiated. Articular surface was smooth with numerous chondrocytes in random arrangement in second zone. Large chondrocytes were in homogenous cartilage matrix in mid zone amongst cartilage canals. Acetabular articular cartilage was appreciable in all post-natal groups since it was clearly differentiated from underlying sub-chondral bone. Ligamentous tissue of acetabular labrum infiltrated into the articular cartilage on one side in specimens of groups II, III and IV. Deeper zone closer to tide mark showed larger chondrocytes in isogenous groups and calcified zone showed atrophied chondrocytes with few areas of calcification. In group III and IV specimens of five and half and eight years old surface of acetabular articular cartilage was uneven in outline. Second zone showed slightly large and oval chondrocytes in lacunae and deeper zone above the calcified part consisted elongated chondrocytes arranged in perpendicular columns. Acetabular labrum blended with articular cartilage of acetabulum at one side invaded by bundles of collagen. Superficial zone was devoid of chondrocytes in articular cartilage of Gr-IV specimens.
