ACL and PCL Stabilizers-Transmitters-Mechanoreceptors
The ACL and PCL center weight thatis transmitted through the knee jointminimizing the amount of wear andtear on the cartilage inside the knee• Mechanoreceptors inside the ACL
and PCL transmit proprioceptive information to the brain giving us perception of sensory 3D time and space
• Proprioception provides neurological input that aids in the stabilization of a joint

The Menisci: Shock AbsorbersThe Menisci: Shock AbsorbersFunction: load bearing• Distribute forces throughout underlying articular
cartilage, minimizing point contact• Bear 40 to 50% of the total load transmitted
across joint in extension • 85% of the compressive load is transmitted
through the menisci at 90 deg of flexion
