Why Does My Knee Hurt?

3 Common Knee Injuries for Athletes

The knee joint is one of the most complex joints in the body and one of the most important for everyday functions. It’s importance only increases for athletes who couldn’t perform the basic functions of their sport without healthy knees. The cruel irony is their frequent use of the knee joint increases their risk of injuring it. Here are a few of the most common knee injuries for athletes.

Meniscus Tears

The meniscus is the cartilage that protects important ligaments in the back of the knee. Usually, a sharp twist or turn while the knee is bent can tear the meniscus. Oftentimes, a torn meniscus won’t cause any symptoms and will heal itself over time. Other times, athletes may report acute pain accompanied by a popping sound or sensation in the knee. Some other symptoms include pain while walking or running, intermittent swelling, and sometimes even locking at the joint.

Patellar Tendonitis

While a torn meniscus comes from a rapid, unnatural motion, patellar tendonitis results from repeated, natural motions. This condition, commonly known as “jumper’s knee,” is extremely common among volleyball and basketball players, who make repeated motions that stress and inflame the tendons in the knee. The symptomatic pain will occur intermittently at the bottom of the knee, making it painful to squat or kneel. If not properly treated, the tendon will become more damaged, leading to more pain.


Commonly known as “runner’s knee,” this injury is a result of softened or deteriorated cartilage. When a person bends their knee, the cartilage provides a surface for the patella, or knee bone, to glide over. If one of the tendons or ligaments doesn’t move properly, the patella can grind against the thigh bone and deteriorate. Symptoms of runner’s knee might include sensations of grinding or cracking, increased pain following prolonged periods of sitting, or increased pain after activities that put a lot of pressure on your knees.
