The patellar tendon connects the kneecap to the lower leg bone. Tendinopathy is an injury to the tendon. It can cause pain, swelling, and limited movement. The injury can include: Tendonitis—inflammation of the tendonTendinosis—tiny tears in the tendon tissue with no significant inflammation
Treatment depends on the severity of the injury.

Tendinopathy is generally caused by overuse of a muscle-tendon unit. Over time, the strain on the tendon causes structural changes within the tendon.
Patellar tendinopathy occurs from overuse of the patellar tendon. Overuse may be caused by any activity that requires: Intense runningJumpingFrequent stops and startsFrequent impact to the kneeFallsTendon weakness from certain diseases
Factors that increase your chance of developing patellar tendonopathy include: Being a physically active teenager or young adultAn increase in the frequency of trainingA sudden increase in the intensity of trainingChanging from one sport to anotherTraining on a hard surfaceRepeated improper movements while trainingMuscle weakness or imbalanceInvolvement in basketball, soccer, volleyball, or running
Symptoms may include: Pain and tenderness in the patellar tendon below the kneecapPain or tightness in the knee when bending, squatting, or straightening the legDiscomfort in the knee when jumping, squating, or walking up stairs
The doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include
Talk with your doctor about the best treatment plan for you. Treatment will depend on the severity of the injury. Options include:
To reduce pain and swelling: Avoid activity that causes pain. Reduce shock or vibrations to the knee.Apply an ice pack for 15-20 minutes at a time, several times a day. Place a towel between the ice pack and your skin.Wrap your injured knee in elastic bandaging. Don't wrap the bandage too tight. It may cut off circulation.Elevate your knee above your heart.
To help manage pain, your doctor may recommend: Over-the-counter pain relievers, such as acetaminophen or non-steroidal anti-inflammatory medication (NSAIDs)Topical pain medications that are applied to the skinPrescription pain relievers
This strap, also called a counterforce brace, can help support the tendon and reduce pain. It is worn as a band just below the knee.
Physical therapy will help: Stretch and condition the quadriceps muscle, which attaches to the patellaMaintain muscle strength, flexibility, and enduranceImprove balance and range of motion
If the treatments above do not reduce inflammation, your doctor may recommend that you consider a cortisone injection. Try to avoid repeated cortisone injections.
You may need surgery if you have advanced damage to the tendon. Your doctor may also recommend surgery if you have not responded to other treatment methods over a period of several months.
To reduce your chances of getting patellar tendinopathy, take these steps: Avoiding activities and sports that repeatedly stress the kneecaps, especially those that involve jumpingRegularly doing quadriceps muscle stretching and strengthening exercisesGradually increasing the frequency and intensity of exerciseLearn proper sporting technique
