Your knee, explained simply
Knee osteoarthritis
Understand the changes. Move with more confidence.

Aches on stairs
Walking or stairs may bring on discomfort.
Stiff after sitting

Swelling or less bend
Your knee may feel puffy or harder to bend.
See the difference
What changes inside the knee?
Cartilage - the smooth covering on your bone ends - becomes damaged. Other joint tissues can change, too.
About these illustrations
AI-created teaching and lifestyle illustrations, not scans or a diagnosis. Symptoms can have other causes; a clinician can assess your knee.
A personal plan
What can help?
-
Keep moving
Choose manageable, low-impact activity such as cycling or swimming.
-
Build strength
Physical therapy can strengthen the muscles supporting your knee.
-
Reduce joint load
Weight management, when appropriate, can ease pressure.
-
Discuss pain relief
Ask about topical medicines, other medications or selected injections.
Surgery may be considered when symptoms remain severe despite other care.
Support as part of treatment
Where a knee brace fits in
A well-chosen brace may help you move more comfortably. Benefits depend on its design and your needs.
- Ease pain during standing, walking or other activities.
- Provide support when your knee feels less dependable.
- Improve daily function so movement feels more manageable.
- Redistribute pressure with an appropriately fitted unloader brace designed for this purpose.
Support has limits. A brace does not rebuild cartilage or replace exercise and medical care. Benefits vary.
Different designs. Different needs.
Photos show product designs, not proof of treatment effectiveness.
Your next step
Start with your activity goals and your clinician’s advice.
How is osteoarthritis diagnosed?
- Your clinician considers your symptoms and examines the joint.
- X-rays may help.
- An MRI is not usually needed.
- Other tests may be used to investigate a different cause of pain.
When should I get checked?
Arrange an assessment if symptoms persist, worsen or interfere with daily activities.
