1. The Knee Joint

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

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

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
