| WHAT IS PATELLAR TENDONITIS (Jumper's Knee)? |
 |
| Patellar tendonitis, also called jumper's knee, is pain in the band of tissue (the patellar tendon) that connects the kneecap (patella) to the shin bone (tibia). |
| HOW DOES IT OCCUR? |
| The most common activity causing patellar tendonitis is too much jumping. Other repeated activities, such as running, walking, or bicycling may also lead to patellar tendonitis. All of these activities put repeated stress on the patellar tendon, causing it to become inflamed. |
| Patellar tendonitis can also happen to people who have problems with the way their hips, legs, knees, or feet are aligned. This alignment problem can result from having wide hips, being knock-kneed, or having feet with arches that collapse when you walk or run, a condition called overpronation. |
| - pain and tenderness around the patellar tendon |
| - swelling in your knee joint, or swelling where the patellar tendon attached to the shin bone |
| - pain with jumping, running or walking, especially downhill or down stairs |
| - pain with bending or straightening the leg |
| - tenderness behind the kneecap |
| HOW IS IT DIAGNOSED? |
| Your doctor will examine your knee to see if you have tenderness at the patellar tendon. He or she will have you run, jump, or squat to see if this causes pain. Your feet will be examined to see if you have a problem with overpronation. X-rays may be taken of your knee. |
