What Is Tendonitis of the Knee?

What Is Tendonitis of the Knee?

For function and mobility, the knee is one of the body’s most important parts. If not for your knees and their ability to bend, you could not walk, run, or jump. Sometimes, from overuse—or even illness—you can sustain injury to the tendon connecting your kneecap to your shinbone. Commonly called tendonitis of the knee, patellar tendinitis can cause severe pain and immobility in both physically active and sedentary adults. To reduce its debilitating and painful effects, it’s important to recognize the signs of patellar tendinitis.

Causes of Tendonitis of the Knee

Also known as jumper’s knee, tendonitis of the knee can be caused by several factors including:

  • Overuse

    Excessive strain from sports like basketball, football, volleyball, and running can contribute to patellar tendinitis.

  • Muscular imbalance

    If some of your leg muscles are stronger than others, they can pull on your patellar tendon, which can lead to tendonitis of the knee.

  • Illness

    Some chronic illnesses can block blood flow to your knee, weakening the tendon. Some examples include kidney failure, lupus, or arthritis.

When it comes to symptoms, pain is the primary and continued symptom you will experience with tendonitis of the knee. Initially, you may only feel pain when you overuse or overextend your knee. However, over time your patellar tendinitis pain will grow and, if left unaddressed, you can experience pain and difficulty performing basic movements like standing and walking.

What Should I Do If I Have Tendonitis of the Knee?

If you’re experiencing patellar tendinitis, your best bet is to simply stop performing strenuous physical activities and high-impact sports. For continued prevention and best practices, it’s best to strengthen your leg muscles as evenly as possible and perfect knee movement techniques. It’s also recommended to undergo frequent physical therapy from licensed professionals.
