Symptoms
By Mayo Clinic staff
Pain is the first symptom of patellar tendinitis. The pain usually is located in the section of your patellar tendon between your kneecap (patella) and the area where the tendon attaches to your shinbone (tibia). During physical activity, the pain may feel sharp — especially when running or jumping. After a workout or practice, the pain may persist as a dull ache.
The pain in your knee may:
- Initially be present only as you begin physical activity or just after an intense workout
- Increase as you step up the intensity of your activity
- Progress to be present before, during and after physical activity
- Make going up and down stairs painful
- Become a constant ache that can make it difficult to sleep at night
