Treat Patellar Tendinitis at MidAmerica’s Palos Hills & Mokena Locations

Anatomy of the Knee

Patellar tendinitis, also known as “jumper’s knee,” is an injury to the tendon connecting the kneecap (patella) to the shinbone (tibia). The patellar tendon works with the muscles at the front of the thigh to enable running, kicking and jumping. This condition is most common in athletes whose sports involve frequent jumping (such as basketball and volleyball players) though it is possible for non-athletes to develop this condition as well. Patellar Tendinitis is common sports injury, and is treatable at MidAmerica’s Palos Hills and Mokena Sports Medicine Clinics. (Mayo Clinic)


Patellar tendinitis is an overuse injury caused by repetitive stress on the knee, causing tiny tears in the tendon which inflame and weaken the tendon over time. Athletes are more at risk to develop this condition because running, jumping, and squatting increase stress on the patellar tendon. (Health Line)

Contributing factors include:

  • Shoes without proper padding
  • Hard playing surfaces
  • Tight leg muscles
  • Uneven leg muscle strength
  • Misaligned feet, legs, or ankles
  • Obesity
  • Chronic diseases that weaken the tendon (Health Line)

Patellar Tendonitis Symptoms

Pain between the kneecap and where the tendon attaches to the shinbone is usually the first sign of patellar tendonitis. Additional symptoms include:

  • Pain during or after physical activity
  • Swelling or burning in the kneecap
  • Pain when kneeling or squatting
  • Pain when climbing stairs, sitting in a car, or rising from a chair

Schedule an appointment with your doctor if patellar tendonitis symptoms last for more than two days, interfere with your ability to perform daily activities, or are associated with swelling or redness at the joint. (Mayo Clinic)

Common Misconceptions

There are two common misconceptions associated with patellar tendonitis:

Myth #1: Tendinitis is caused by inflammation

While inflammation can be involved in tendon pain, it is not its primary driver. The main cause of tendon pain is mechanical overloading, the result of which is inflammation. This is why, more frequently, physicians are referring to tendon pain as “tendinopathy” to more accurately reflect its pathology. (Velocity Sports Rehab)

Myth #2 Rest is Best

In the initial stages of treating tendonitis, reducing workload on the tendon may be necessary to calm inflammation. However, prolonged resting can cause stress-shielding which causes the tendon to weaken. Also, returning to the same activity level after long periods of rest spikes the load on the tendon, increasing the likelihood of reinjury. (Velocity Sports Rehab)


On your initial visit, your physician may apply pressure to parts of your knee to determine the source of the pain. Usually, pain from patellar tendinitis is located at the front of the knee, just below the kneecap. Your physician may also extend your knee to test your range of motion. (Health Line)

Additionally, your doctor may schedule an X-ray to exclude other bone problems that can cause knee pain, an ultrasound, to reveal possible tears in your patellar tendon, or an MRI to reveal subtle changes in the patellar tendon. (Health Line)

Patellar Tendonitis Treatment

Most cases of patellar tendonitis do not require surgery and a multitude of non-operative treatment options are available, including:


Medications such as ibuprofen and naproxen may provide short-term pain relief

Physical Therapy

Sessions include stretching exercises to reduce muscle spasms and strengthening exercises to improve thigh muscle strength

Patellar tendon strap

A strap that applies pressure to the patellar tendon to distribute force away from the tendon, thus reducing pain

Corticosteroid Injection

An injection in the area around the patellar tendon proven to reduce severe pain. However, this method may weaken the tendon and make it more likely to rupture. (Spine Ortho Center)


If non-surgical methods have proven ineffective, surgery is available at MidAmerica’s Palos Hills and Mokena locations. Most commonly, arthroscopic surgery is used to treat this condition. This method involves making four small incisions at the knee, removing abnormal tissue and the lower portion of the patella. This surgical method encourages a more natural healing process and has a shorter recovery time than traditional methods. Recovery time from surgery varies, however, most patients are able to return to high level activity in three months to a year. (Health Line)
