THE nutrition of the chondrocytes of articular cartilage is derived in part at least from the synovial fluid, by diffusion through the matrix 1. Many workers have studied the permeability of cartilage ...

Post-traumatic osteoarthritis develops rapidly after joint injury, yet current treatments largely address symptoms rather ...

Micropores in fabricated tissues such as bone and cartilage allow nutrient and oxygen diffusion into the core, and this novel approach may eventually allow lab-grown tissue to contain blood vessels, ...

"Cartilage is a critical component in our joints," said Northwestern's Samuel I. Stupp, who led the study. "When cartilage becomes damaged or breaks down over time, it can have a great impact on ...

Your knee contains articular cartilage, which lines your bones and allows you to move without pain or friction. Knee cartilage damage occurs when your articular cartilage chips or wears away. In ...

Your hip cartilage is a smooth surface that cushions the ball and socket of the hip joint to keep your bones from rubbing against each other. A hip injury or trauma to the hip could wear down your ...

Two innovative new developments out of the same laboratory have demonstrated that degraded cartilage can be repaired and regrown, first by using "dancing molecules" to target the proteins needed for ...

Northwestern University scientists have developed a cell-free bioactive material comprising a complex network of molecular components that work together as a scaffold to mimic cartilage’s natural ...

Knees contain two types of cartilage: articular and meniscus. Articular cartilage helps the knee move freely. Meniscus cartilage serves as a cushion or shock absorber between the bones. Sports ...
