Calcium pyrophosphate dihydrate crystal arthropathy preferentially affects large joints and intervertebral discs (Pritzker et al., ).Gross examination demonstrates the crystals as punctate white deposits within the articular tissues (Figure ).This contrasts with gout in which the crystals aggregate as a white paste on the articular surfaces.

PP i is a potent inhibitor of the nucleation and propagation of BCP crystals. 19 Concordantly, maintenance of physiologic extracellular PP i levels by chondrocytes and certain other cells serves to suppress calcification.

(Chondrocalcinosis articularis or calcium pyrophosphate dihydrate crystal deposition diseases).Cited by: An ultrastructural study of articular cartilage from five patients with calcium pyrophosphate dihydrate (CPPD) crystal deposition disease was performed.
The CPPD crystals, identified by micro X-ray diffraction, were usually found in clusters, located in intercellular areas of the intermediate cartilage by: This chapter provides an overview of tissues unique to synovial joints, articular cartilage, and meniscus. The development and cellular and (bio)chemical composition are described, as well as the role of mechanical stimuli.
In addition, the role of growth factors in cartilage and meniscus homeostasis, cellular differentiation, and chondrocyte hypertrophy are discussed. An ochronotic femoral head has been studied morphologically under the light and the electron microscope.
Its articular cartilage showed the alterations already reported in the literature, mainly consisting of erosions of the surface, pigment accumulation in chondrocytes and intercellular matrix, chondrocyte degeneration, the formation of pigmented, calcified and uncalcified microshards, Cited by: Three‐dimensional (3D) double echo stead‐state (DESS) MRI utilized for the assessment of articular cartilage morphology.
The data were acquired in sagittal orientation (A) and was reoriented into coronal (B) and axial (C) datasets for segmentation of articular cartilage.
In‐plane resolution: × mm. Slice thickness: mm. In the present study we showed that there is a significant correlation between clinical symptoms and the amount of mineralized articular cartilage. Mitsuyama et al (10) recently showed that age, rather than the presence of OA, is the predominant factor driving progressive pathologic calcification in articular cartilage.
Osteoarthritis (OA) is the commonest condition to affect synovial joints, but although any synovial joint can be affected, most studies of pathology relate to large joints (knees and hips).
OA involves the whole joint and pathological alterations typically occur in all joint tissues. Established OA is characterized by a mixture of tissue loss and new tissue production resulting in focal loss.
Scanning electron microscopy, in conjunction with freeze-fracturing and freeze-drying preparation techniques, was used to characterize the morphology and distribution of crystal deposits foundin situ in the articular cartilage of threepost mortem human knee joints.
Energy dispersive analysis and X-ray diffraction were used to analyse the chemical composition of the individual crystals.

The therapeutic effects of bovine articular cartilage on adjuvant-induced arthritis in Kunming mice were investigated in the present study. Animals were divided into control group, model group and treatment groups (bovine articular cartilage, polysaccharide from bovine articular cartilage, polysaccharide from bovine laryngeal cartilage; administered orally by gastric intubations, mg/kg/d.
In both diseases, there is mineralization of the articular cartilage and menisci, synovial hypertrophy, and cartilage thinning. Most patients also have OA (1, 2).
It is possible that the increased mineralization observed in humans with chondrocalcinosis and BCP crystal deposition disease could result in altered joint biomechanics, ultimately.
