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

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

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

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

5. Anatomy: 4 bones Femur Tibia Fibula Patella

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

8. 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

9. Anatomy Muscles Quadriceps Knee extension Hamstrings Knee flexion Gastrocnemius Knee flexion

10. 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
