‘”Your knee joint is a combination where your thigh bone comes together with your lower leg bone, your femur with your tibia. In between those two bones, you have these two cartilage cushions that act as, relatively, shock absorbers for the joints and those are called your menisci. Those are kind of a spongy type of cartilage that helps to prevent the bones from impacting each other. Now, because those are a little bit soft, they can be prone to damage and these things can get damaged in a lot of different ways,” explains Dr. Jason Matuszak, Chief of Sports Medicine at Excelsior Orthopedics.’
