How common is knee pain in patellar tendinitis?

Pain is often felt between the kneecap and the shinbone and may be tender when touched. Jumping, running, squatting, stairs, or repeated kicking can bring it on, and stiffness may follow activity. Symptoms may build gradually or appear after a change in training. Knee pain is not specific to patellar tendinitis, so the location and activity pattern need assessment.

Temporarily reduce jumping, sprinting, deep squats, and other movements that clearly increase pain. Keep comfortable daily movement and use a gradual strengthening plan guided by a physiotherapist or clinician. Do not test the tendon repeatedly by pushing through sharp pain. A review can also check the kneecap, joint, muscles, and nearby tendons.

Arrange an assessment when pain interferes with sport, work, stairs, or ordinary walking, or when it is not settling with activity adjustment. Seek urgent care after a sudden snap, loss of strength to straighten the knee, major swelling, or inability to bear weight. A hot, red knee with fever also needs prompt medical attention.

Ask whether the pain is coming from the patellar tendon, how to modify training, which strengthening exercises are appropriate, and how quickly to progress activity.
