- Static Stabilizers
The static stabilizers are the four major ligaments of the knee: the anterior cruciate ligament (ACL), the posterior cruciate ligament (PCL), the medial collateral ligament (MCL), and the lateral collateral ligament (LCL).
- Dynamic Stabilizers
The dynamic stabilizers of the knee are the muscles and tendons that surround the joint. These muscles and tendons are controlled by what's known as neuromuscular input, the unconscious activation of these structures to control the position of the joint.
One of the better known neuromuscular training programs, the Prevent Injury, and Enhance Performance program (commonly known as the PEP program), was developed at the Santa Monica Orthopaedics and Sports Medicine Research Foundation.
