The knee meniscus is a C-shaped structure made of fibrocartilage which functions as a shock absorber during daily activities. It is located within the knee between the top bone (femur) and the bottom bone (tibia). There, it not only protects the lining of the knee (hyaline cartilage) by its cushioning effect, but also protects the ligaments of the knee by acting as a stabilizer.
Here is a very good article detailing why.
With the Olympics over and school starting, it’s important to think about staying injury-free as the fall sports season begins. Athletes in sports involving running, jumping, landing, twisting, and pivoting are at a higher risk for serious knee ligament injuries.
