The knee is considered to be the largest joint in the human body. A healthy knee is highly important as it enables one to walk, turn and perform multiple activities without any hassle. Since it is the connecting joint between the upper and lower legs’ bones, it enables the leg to bend and also provides the stability that supports one’s body weight. Your knee joint comprises of three bones. The thigh bone (femur) is located right above the shinbone, also known as the tibia. When you twist or unbend your knees, the circular end of your thigh bone rotates and slides through the relatively flat topside of the shinbone.

The third bone is known as the kneecap (patella), which accompanies the muscles, that enables you to unbend your knees. The knee cap gives you the advantage and lessens the strain on the muscles.

This problem arises, when the triangular bone (patella) that is the front covering of your knee, hatches out of its place. 

In certain cases, the displaced kneecap stays, that further makes the dislocation visible.
