Precision of Hyaline Cartilage Thickness Measurements

Proteoglycans of Hyaline Cartilage

Proteoglycan monomers from guinea-pig costal cartilage, bovine nasal and bovine tracheal cartilage were observed in the electron microscope after being spread in a monomolecular layer with cytochrome c. The proteoglycan molecule appeared as an extended central core filament to which side-chain filaments were attached at various intervals. The molecules from the three sources displayed great ult...

Staining properties of hyaline cartilage.

Despite numerous attempts to develop and evalute specsc methods for the histochemical demonstration of mucopolysaccharides, definitive information is not readily available. Thls is in spite of the notable contributions of Hale ('46); Steedman ('50); Gomori ('50); Kramer and Windrum ('54); Mowry ('56, '58); Spicer ('60); Belanger and Migicovsky ('61) and Goldstein ('62) to mention only a few.

Toward standardized ultrasound measurements of cartilage thickness in children.

Which cartilage is regenerated, hyaline cartilage or fibrocartilage? Non-invasive ultrasonic evaluation of tissue-engineered cartilage.

OBJECTIVE To investigate ultrasonic evaluation methods for detecting whether the repair tissue is hyaline cartilage or fibrocartilage in new cartilage regeneration therapy. METHODS We examined four experimental rabbit models: a spontaneous repair model (group S), a large cartilage defect model (group L), a periosteal graft model (group P) and a tissue-engineered cartilage regeneration model (...

Magnetic resonance imaging of knee hyaline cartilage and intraarticular pathology.

Injuries to the hyaline cartilage of the knee joint are difficult to diagnose without invasive techniques. Even though these defects may be the most important prognostic factors in assessing knee joint injury, they are usually not diagnosed until arthrotomy or arthroscopy. Once injuries to hyaline cartilage are found and/or treated, no technique exists to follow these over time. Plain radiograp...
