Patellar Tendinitis

Patellar Tendinitis, also called "Jumper's Knee," is commonly seen in athletes whose sports require a lot of jumping or repetitive motions.

What is Patellar Tendinitis?

The patellar tendon is located in the front of your knee and attaches from the patella (kneecap) to the upper shin. Patellar tendinitis is common in athletes and is caused by inflammation of the tendon which causes pain in the front of the knee.

Signs and Symptoms

There are a few signs and symptoms that can lead to the diagnosis of patellar tendinitis, these include:

  • Pain in the front of the knee specifically at the patellar tendon
  • Knee pain after prolonged sitting
  • Pain with climbing stairs

Causes and Risk Factors

Some contributing factors as well as common acitivities that may exacerbate this condition include:

  • Overall weakness: especially in the quadriceps, hips, and core
  • Decreased range of motion: specifically in the quadriceps, hamstrings, and IT band
  • Poor positioning of the patella (kneecap)
  • Lack of proper footwear
  • Repetitive stress to the patella, including recreational activities that involve jumping: volleyball, basketball, etc.
