[Effect of articular cartilage resection on the growth and formation of the femoral and acetabular epiphyses].
Different parts of the articular cartilage were resected in 46 rabbits at the age of 2.5 months. The resected narrow stripe of the articular cartilage completely restored by the 60--90th day and the growth of the condyles was not disturbed. Resection of considerable areas of the articular cartilage on the condyles and on the femoral head was accompanied by a certain disturbance of the osseous tissue growth in these areas with  resulted impression of the condyles, deformation of the head and further formation of coxa vara. The removal of 1/3 of the articular cartilage of the cotyloid cavity resulted in a certain increase of its diamter, uneven development at the site of resection; the femoral head of this joint increased, its spherical shape was altered. The restored cartilage did not restore its original structure characteristic for a growing bone. The newly formed articular cartilage lost its ability to participate in endochondral bone formation during the growth of the animal.
