The Knee One of the most complex & most injured joints in the body

Objectives List the bones that comprise the knee joint List the stabilizing ligaments Describe the function of the knee and meniscus

Stability relies on: 1. Ligaments 2. Joint capsule 3. Muscles

Knee functions to provide: Stability in weight bearing Mobility in locomotion

Anatomy: 4 bones Femur Tibia Fibula Patella

Anatomy Meniscus Medial & lateral Bowl shaped Thicker on the outside border; thinner inside Functions: to increase knee stability cushion stresses placed on the knee

Anatomy Ligaments Major stabilizing ligaments Cruciate ligaments (ACL & PCL) ACL keeps the femur from moving posteriorly PCL keeps that femur from sliding anteriorly Collateral ligaments (MCL & LCL) Protect against side-to-side forces

Anatomy Muscles Quadriceps Knee extension Hamstrings Knee flexion Gastrocnemius Knee flexion

Prevention of knee injuries Physical conditioning, rehab, skill development, shoe type Total body conditioning Strength, flexibility, cardiovascular & muscle endurance, agility, speed, balance Strength balance between the hamstrings and quads Shoe type Length of cleats?? Knee braces
