without letting the tibia slide too far posterior (Scuderi & Tria, 2010). These are the four most important ligaments in the knee that give the knee the most stability which are shown in Figure 3. Although the patellar ligament aides the stability of the knee, it is not as strong as the rest of the structure. Lastly, the iliotibial band (IT band) runs along the outside of the leg from the hip to the knee. The purpose of this is to limit lateral movement along the knee (Scuderi & Tria, 2010).
Stability is the most important function of the knee. To add to knee stability are the tendons. Tendons are elastic tissues that connect muscles to bones. They are what stabilize the knee and there are two major tendons that run through the knee.

The quadriceps tendon connects the quadriceps muscles from the thigh to the kneecap. It is what provides the power for extending the knee, according to Marieb and Hoehn, 2013. The quadriceps tendon also helps hold the patella in the patellofemoral groove in the femur. The other tendon in the knee is the patellar tendon. The patellar tendon connects the kneecap to the tibia (shinbone). Although this structure helps with stability, it very vulnerable and is easily injured.
The next structure that is mentioned is the cartilage in the knee. A joint is covered in articular cartilage, the name articular coming from the fact that when the bones rub together they are articulating (Scuderi & Tria, 2010). Articular cartilage is fibrous connective tissue that is white, smooth and it covers the ends of the bone and as the joint moves it protects it, as mentioned by

gives a good representation of where these muscles are located. The muscles that are in the leg keep the knee stable and aligned. Those muscles are the quadriceps and hamstrings. Based on the information presented by Scuderi and Tria, these are the two main muscle groups that are in charge of the knee (2010). There are four muscles that are in front on the thigh and those muscles are responsible for bring a bent knee to the straight position. These four muscles are the vastus lateralis, vastus intermedials, vastus medials and the rectus femoris. These play an important role in jumping, running, climbing and getting up from a seated position. In 2013, Marieb and Hoehn reported that the hamstring group is made up of three muscles on the back of the thigh and is what control the knee movement from a straight position to a bent position. The hamstring group cross both the hip and knee joints and are the main movers in knee flexion and thigh extension. These three muscles are the biceps femoris, semitendinosus, and the semimembranosus
