2 What is the knee joint? The knee joint is made up of the articulation of the ____________ __________________. The femur however does not come in contact with the fibula, but the fibula interacts with the tibia.

3 Type of Joint The knee joint was first thought to be a ____________________because it was believed to be responsible for only flexion and extension However, the knee can rotate the leg medially and laterally to a small degree Therefore, the knee is considered also to be a ___________________________joint which is a type of synovial joint

4 The Knee Joint – Anterior Patella Medial (Tibial) collateral ligament Patellar ligament Tibial tuberosity Tibia Quadriceps tendon Fibula

5 The Knee Joint Anterior (deep) Femur Lateral (Fibular) collateral ligament removed Medial (Tibial) collateral ligament removed Lateral Meniscus Tibial Tuberosity Fibula Lateral CondyleMedial Condyle Medial Meniscus Tibia Posterior cruciate ligament Anterior cruciate ligament

6 The Knee Joint – Posterior Femur Adductor magnus tendon Medial head of gastrocnemius tendon Semimembranosus tendon Medial (Tibial) collateral ligament Lateral (Fibular) collateral ligament Fibular head Lateral head of gastrocnemius tendon Oblique popliteal ligament Fibula Tibia

7 The Knee Joint – Posterior (deep) Anterior cruciate ligament Popliteal tendon Lateral meniscus Lateral (Fibular) collateral ligament Medial (Tibial) collateral ligament Medial meniscus Posterior cruciate Femur Fibula Tibia Posterior meniscofemoral ligament

8 Meniscus The end of the femur is covered with articulating cartilage which rests at the end of the tibia There lie two thick fibrocartilage articular discs called the menisci (meniscus-singular): ________________________________________________________ They sit on the tibial condyles which are located on either side of the intercondylar eminence

9 Intrinsic Ligaments  The knee joint has several ligaments which help attach the femur and tibia together  The two intrinsic ligaments which cross each other are called the _____________ligaments _________ _____  The _________ (anterior cruciate ligament) helps stop anterior movement of the tibia and the _____ (posterior cruciate ligament) helps to prevent posterior movement

10

11 Extrinsic Ligaments _____) _____)  The knee joint is held together medially by the medial collateral ligament (_____) and laterally by the lateral collateral ligament (_____)  These ligaments provide medial and lateral stability of the knee
