2. F. The Knee 1. Largest joint in the body consisting of 3 joints a. between the patella and the femur (gliding) b. Lateral condyles of the femur and tibia (hinge) c. Medial condyles of the femur and tibia (hinge)

3. 2. Consists of ten components a. Articular capsule- ligamentous sheath of muscle tendons that encase the joint b. Medial and lateral patellar retinacula- quadriceps muscle tendons support the anterior surface c. Patellar ligament- purpose is to strengthen the anterior 1. Has a pad of fat for separation and cushioning

5. d. Oblique popliteal ligament- posterior ligament connecting femur and tibia 1. Gives posterior strength e. Arcuate popliteal ligament- connects femur to the fibula 1. Gives lower lateral strength on posterior f. Tibial(medial) collateral ligament- connects medial area of femur to medial portion of tibia

7. g. Fibular (lateral) collateral ligament- lateral surface of the femur connects to the lateral surface of the fibula h. Intracapsular ligaments: 1. Anterior cructiate ligament (ACL)- goes from the anterior of the tibia to the posterior medial portion of the femur 2. Posterior cruciate ligament (PCL)- goes from the posterior of tibia to the anterior medial area of the femur

9. i. Articular disc- Fibrocartilage discs between femur and tibia; both lateral and medial menisci j. Bursae- a sac or pouch of synovial fluid located at friction points 1. In knee they are anterior, medial, and lateral
