Document Summary
Frequently inured due to stress and rotational component (tibia) Relies on stability from ligaments, joint capsule and surrounding muscles. Knee provides stability in weight bearing and mobility in locomotion. Meniscus (medial and lateral)- fibrocartilage disks shaped like bowls. Cushion any stress placed on the knee joint (separate femur and tibia) Cruciate ligaments (rotation forces: anterior cruciate ligament (acl, posterior cruciate ligament (pcl) Stabilize the knee against side to side forces: medial collateral ligament (mcl) b. Strength, flexibility, cardiovascular, muscular endurance, agility, speed and balance muscles around the hip and knee must be conditioned to maximize stability (quadricep hamstrings, gastrocnemius) Long conical cleats are being replaced with short and broad cleats in football and other sports. These cleats allow for foot control but don"t fix to the ground easily. Functional knee braces are worn to provide support following an injury. Can be custom molded and designed to control rotational forces and tibial translation. Determining the mechanism of injury is critical.
