Jumpers Knee





The patellar tendon connects the kneecap (the patella) to the shin bone. This is part of the ‘extensor mechanism’ of the knee, and together with the quadriceps muscle and the quadriceps tendon, these structures allow your knee to straighten out, and provide strength for this motion. The patellar tendon, like other tendons, is made of tough string-like bands. These bands are surrounded by a vascular tissue lining that provides nutrition to the tendon.

The quadriceps actively straightens the knee in jumping to propel the individual off the ground as well as functioning in stabilizing their landing. It helps your muscles extend your lower leg so that you can kick a ball, push the pedals on your bicycle and jump up in the air.


  • Patellar tendonitis is the condition that arises when the tendon and the tissues that surround it, become inflamed and irritated. This is usually due to overuse, especially from jumping activities. This is the reason patellar tendonitis is often called “jumper’s knee.”
  • When overuse is the cause of patellar tendonitis, patients are usually active participants of jumping-types of sports such as basketball or volleyball.
  • Patellar tendonitis may also be seen with sports such as running and soccer.
  • Also, some patients develop patellar tendonitis after sustaining an acute injury to the tendon, and not allowing adequate healing. This type of traumatic patellar tendonitis is much less common than overuse syndromes.


  • Pain at the bottom and front of the kneecap especially when pressing in or palpating
  • Aching and stiffness after exertion.
  • Pain increases as one steps up the intensity of the exercise
  • Going up and down stairs is painful.
  • Pain when you contract the quadriceps muscles.
  • The affected tendon may appear larger than the unaffected side.
  • May be associated with poor Vastus medialis obliquus (VMO) function
  • Calf weakness may be present


Physical examination. Your doctor may apply pressure to different parts of your knee to determine exactly where you’re experiencing pain. Pain associated with patellar tendinitis usually concentrates on the front part of your knee, just below your kneecap.

Ultrasound. This test uses sound waves to create an image of your knee, revealing the location of tears in your patellar tendon.

Magnetic resonance imaging (MRI). MRI uses a magnetic field and radio waves to create images that are more detailed than ultrasound images. MRI can reveal more subtle changes in the patellar tendon.

A combination of tests may help your doctor rule out other conditions that can cause knee pain similar to patellar tendinitis, such as:

Pain behind your kneecap (patellofemoral pain syndrome)

Tears in the cartilage (meniscus) that cushions your knee joint

Breakdown of the cartilage underneath your kneecap (chondromalacia patella)



At Physioline, all the members of the rehabilitation team work together so as to provide proper care and the therapy in order to:

  • Pain relief with electrotherapy
  • Reduce swelling
  • Reduce stiffness
  • Flexibility training
  • Strengthening of muscles
  • Regain full range of motion
  • Sports specific training


 Chopat Straps/Braces

Occasionally, your doctor will provide a support strap (called an infrapatellar strap or a Chopat strap), a knee brace, or custom orthotics. The benefit of these measures in the treatment of patellar tendonitis is not well known, but some patients find complete relief from using these products.


 Anti-Inflammatory Medications

Nonsteroidal anti-inflammatory medications (NSAIDs) include a long list of possibilities such as Ibuprofen, Motrin, Naprosyn, Celebrex, and many others. Patellar tendonitis treatment can be improved by these medications that will decrease pain and swelling. Be sure to talk to your doctor before starting these medications
