The meniscus is a thick band of cartilage tissue, in between two joints made by the tibia and femur. It makes the joints more flexible.  Our knee joint is also protected by fluid sac, also known as bursae.  These bursae help decrease unnecessary tears and friction of the tendons. This fluid increases the mobility of your joint. Here large tendon covers the knee cap and connects with the anterior part of the tibia bone.

Our knee allows us to move and bend our leg. Gives the ability to walk, run, and can do our regular activity.
