Prevention

To reduce your risk of developing patellar tendinitis, take these steps:

• Don't play through pain. As soon as you notice exercise-related knee pain, ice the area and rest. Until your knee is pain-free, avoid activities that put stress on your patellar tendon.
• Strengthen your muscles. Strong thigh muscles are better able to handle the stresses that can cause patellar tendinitis. Eccentric exercises, which involve lowering your leg very slowly after extending your knee, are particularly helpful.
• Improve your technique. To be sure you're using your body correctly, consider taking lessons or getting professional instructions when starting a new sport or using exercise equipment.
