Treatment of chondromalacia patellae by lateral retinacular release of the patella.

abstract：BACKGROUND:Soluble factors released from chondrocytes can both enhance and induce chondrocyte-like behavior in cocultured dedifferentiated cells. The ability to similarly prime and modulate biosynthetic activity of differentiated cells encapsulated in a three-dimensional environment is unknown. QUESTIONS/PURPOSES:To u...
