Firstly, discuss what type of joint the knee is.

Secondly, discuss muscle contraction of the hamstring muscle group.

Thirdly, discuss how flexion is achieved.

Further, discuss the role of tendons in the process. If you have enough words, you can also include a brief discussion of the overall process of muscle contraction.

How Does The Knee Work?

In this article we’ll look at the knee in more detail, examine how it works and identify the areas where things can go wrong.

The Joint

The knee is one of the largest and most complex joints in the body, it is a pivotal hinge joint. This type of joint permits bend and extension as well as small amounts of internal and external rotation. Due to its limited range of motion and the heavy load it carries the knee joint can be prone to injuries.

Knee bones

The knee joins the thigh to the shin and is made up of 4 bones; femur, tibia, fibula and patella. The femur is the thigh bone which connects to the tibia, the shin bone. The fibula is a smaller bone which runs alongside the tibia and also forms the lateral part of the ankle joint. Additionally, patella is commonly known as the kneecap and is a triangular piece of bone that sits in a groove at the lower end of the femur.

Tendons explained

Tendons are tough bands of connective tissue connecting the knee bones to the leg muscles that move the joint. Ligaments are made up of tough bands of tissue too but ligaments connect bone to bone. The knee joint has four major ligaments joining the bones together to keep the knee stable. The anterior cruciate ligament (ACL) prevents the femur from sliding backwards onto the tibia and the posterior cruciate ligament (PCL) prevents the femur from sliding forwards onto the tibia…..
