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.

The Microhardness of Articular Cartilage
Clinical Orthopaedics and Related Research, 1975The standard metallurgical technique of microhardness testing was useful for investigations on the physical properties of articular cartilage. The problem of visco-elasticity of the cartilage was overcome by using a brittle lacquer coating as a memory device. The surface layer was the hardest plane when the superficial layer was intact.

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.

Microfracture of Articular Cartilage
JBJS Reviews, 2016➢ Microfracture is a treatment option for symptomatic, full-thickness cartilage defects.➢ Microfracture is most likely to be successful when performed in nonobese patients under the age of thirty years for small (<2 to 4-cm2) femoral condylar defects that have been symptomatic for a short time (less than twelve to twenty ...

Restoration of Articular Cartilage
Journal of Bone and Joint Surgery, 2014➤ Novel (i.e., quantitative and semiquantitative) cartilage imaging techniques can evaluate cartilage composition to augment information obtained from traditional magnetic resonance imaging sequences that detail morphology.➤ A well-defined role for drugs leading to chondroprotection has not yet been determined.➤ Shortcomings of bone marrow stimulation ...

Regeneration of Articular Cartilage
2005Loss of articular cartilage from the ends of bones forming diarthrodial joints can be the source of profound pain and disability, and eventually lead to complete degeneration of the joint, necessitating total joint replacement. Until a few years ago, there seemed little hope of treating such defects.

Lubrication of Articular Cartilage
Annual Review of Biomedical Engineering, 2016The major synovial joints such as hips and knees are uniquely efficient tribological systems, able to articulate over a wide range of shear rates with a friction coefficient between the sliding cartilage surfaces as low as 0.001 up to pressures of more than 100 atm. No human-made material can match this. The means by which such surfaces maintain their

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 ...
