Anatomy and biomechanics of the menisci

The shape of the menisci and the orientation of the collagen fibers are optimal for weight bearing and shock absorption. The menisci are of clinical importance to knee biomechanics as they function to maintain knee joint stability and congruity, resist capsular and synovial impingement during knee motion, support the screw home mechanism, and distribute load over a large area of the articular surface. Because of these vital roles, an attempt should be made to save viable meniscus when performing knee surgery.
