fibrocartilage C-shaped cushoins in knee, relatively vascular (outer region vs. AC-completely avascular)
Structure+composition of meniscus
fibrchondrocytes(synthesize type 1 collagen fibers), key general points, macromolecules, 65-70%H2O vs. AC-up to 80%
function of meniscus
load bearing(axial loads+circumferential str), shock absorbtion(compressive stiffness, 1/2 of AC)
injury/healing of meniscus
happens when a traumatic load exceeds strength of the meniscus, meniscal degeneration beings gradually ~30 tearing is messy
arthroscopic, sutures, tear must be peripheral, slow to heal but keeps orig cartilage
