The morphologic changes of articular cartilage with bone grafting to fill subchondral bone defects were studied in 23-month-old New Zealand rabbits with bilateral tibial subchondral bone defects. The defects were made approximately 5 mm below the articular surface and were covered with surrounding tissues. The right side was filled with calcium sulfate

Articular cartilage transplantation
Human Pathology, 1977This report describes the biopsy findings in four of 30 patients treated with cadaver osteochondral shell allografts for osteoarthritis in the knee. This study demonstrates that graft cartilage cells can survive in excess of 25 months, and that host bone can completely replace graft bone by creeping substitution.

Articular cartilage is a complex tissue maintained by chondrocytes, which undergo metabolic changes as a result of aging, disease, and injury. These changes may hinder tissue maintenance and repair, resulting in accelerated loss of articular surface and leading to end-stage arthritis.

The acute and repetitive impact and torsional joint loading that occurs during participation in sports can damage articular surfaces causing pain, joint dysfunction, and effusions. In some instances, this articular surface damage leads to progressive joint degeneration. Three classes of chondral and osteochondral injuries can be identified based on the

Articular cartilage can tolerate a tremendous amount of intensive and repetitive physical stress. However, it manifests a striking inability to heal even the most minor injury. Both the remarkable functional characteristics and the healing limitations reflect the intricacies of its structure and biology.

Synovial joints allow the efficient and controlled movement necessary for sport with a biological shock-absorbing bearing of hyaline cartilage. This is an extremely low friction surface, with a coefficient of one-sixth of that of ice on ice, lower than most man-made bearing materials.

Fracture of Articular Cartilage
Journal of Biomechanical Engineering, 1996Crack formation and propagation is a significant element of the degeneration process in articular cartilage. In order to understand this process, and separate the relative importance of structural overload and material failure, methods for measuring the fracture toughness of cartilage are needed.

CALCIFICATION IN ARTICULAR CARTILAGE
The Journal of Bone and Joint Surgery. British volume, 1960A case of calcification of articular cartilage in association with a parathyroid tumour is described. Previously reported cases of articular calcification are briefly discussed, and it is recommended that patients with articular calcification of undetermined cause should be investigated for hyperparathyroidism.

Fatigue of Articular Cartilage
Nature, 1973IT has been suggested1 that fibrillation, the earliest change in osteoarthritic cartilage visible to the naked eye, may be the result of fatigue failure. Abnormally high stresses in the superficial layer of cartilage could be produced by unusually high applied loads, incongruity of the joint surface, or softening of the cartilage by mucopolysaccharide ...
