Does this sound familiar?
Pain below the kneecap
The tendon may feel tender during loading.
Aches with jumping
Running, landing or stairs may provoke pain.

What happens in the tendon?
The patellar tendon joins your kneecap to your shinbone. Repeated loading can outpace its ability to recover, making it painful.

A personal plan
What can help?
-
Adjust painful loads
Reduce aggravating jumping or running while staying active in suitable ways.
-
Build tendon capacity
Follow a progressive strengthening plan with your physical therapist.
-
Review pain relief
Ask which short-term options are suitable for you.
-
Reassess persistent symptoms
Treatment can be adjusted if progress stalls. Surgery is rarely needed.
Support as part of care
Where a patellar strap fits in
A strap may ease tendon-related pain for some people during suitable activity.
- Targeted pressure may reduce discomfort at the tendon.
- Low-profile coverage leaves most of the knee uncovered.
- Adjustable fit lets you set a comfortable level of pressure.
- A useful add-on can accompany your prescribed exercise plan.
Support has limits. A strap does not heal the tendon or replace progressive rehabilitation. Less pain is not permission to increase loads suddenly.
Different designs. Different needs.

Your next step
Match your support and activity plan to your needs.
How is it assessed?
- Your clinician reviews the pain pattern and examines the tendon.
- Imaging is not always needed.
- Ultrasound or MRI may help clarify tendon changes or a possible tear.
When should I get checked?
Seek prompt care after a sudden pop, major swelling or an inability to straighten the knee; these may signal a tendon tear.
