3.Tendons
These thick, fibrous cords connect muscle to bone so you can move your limbs. Your quadriceps tendon links your kneecap to the muscles on top of your thigh. Your patellar tendon continues down the leg and ties your knee to your shin.
4.Meniscus
When the doctor says you’ve torn cartilage in your knee, it’s most likely these two triangle-shaped pieces. They work as shock absorbers between your thighbone and your shinbone, two of the biggest bones in your body. That’s why they’re more rubbery than other cartilage you have, including the rest of what’s in your knee.
