The quadriceps and patellar tendons can be stretched and torn. Although anyone can injure these tendons, tears are more common among middle-aged people who play running or jumping sports. Falls, direct force to the front of the knee, and landing awkwardly from a jump are common causes of knee tendon injuries.
Torn cartilage: In the knee joint there are two types of cartilage, articular cartilage and meniscal cartilage. The meniscus is a triangular shaped piece of fibro-cartilage that sits between the femur and tibia. The meniscus can tear as a result of injury or secondary degenerative changes that occur over time.
