Knee Pain: 4 Common Causes

Knee Pain: 4 Common CausesThe largest joint in the human body is the knee, which is where three bones meet: the femur (thighbone), tibia (shinbone), and patella (kneecap). Knees endure intense stress and thus are commonly injured. While knee injuries are most associated with athletes, such injuries also regularly occur in manual laborers. If you're suffering from persistent knee pain, you may have an underlying condition that requires medical attention, at which point treatment can provide you relief and improve your quality of life. Here's a look at four common sources of serious knee pain.

Cartilage Tears

Cartilage provides the knee with cushioning and stabilization. In the knee, there are menisci that are formed from cartilage. When a knee becomes severely twisted, the meniscus may tear. This can cause serious pain and swelling.


Osteoarthritis is very common, affecting more than 30 million Americans. In knees, osteoarthritis can cause the degradation of joint cartilage, leading to pain and stiffness. To minimize the effects of arthritis in knees, it's important to maintain a healthy weight.


Tendonitis is caused by inflammation in tendons, resulting from repetitive stresses on the knees. Often, tendonitis occurs in the patellar tendon, where the quadriceps muscles and kneecap come together. Symptoms of tendonitis include burning and swelling.

Torn Ligaments

Torn ACLs (anterior cruciate ligament) are one of the most notorious injuries in sports. With fully torn ACLs, surgery is typically required. Partial tears, however, are sometimes treated without surgery. MCL (medial collateral ligament) and LCL (lateral collateral ligament) tears are also quite common and can put athletes on the shelf for extended periods of time.
