Frequently Asked Questions

How do I know if my knee pain is due to osteoarthritis? + –

Osteoarthritis typically causes stiffness, swelling, and a gradual increase in pain—often worse after rest or prolonged activity. You might also hear creaking (crepitus) when bending your knee. A proper diagnosis usually requires a physical exam, imaging like X-rays, and a review of symptoms by a medical professional.

Do I need surgery for knee arthritis or osteoarthritis? + –

Not always. Many people manage their osteoarthritis conservatively through weight management, exercise, and bracing to offload pressure from the knee. Surgery may be considered if conservative approaches fail and pain or mobility problems severely affect quality of life. Consult an orthopedic specialist for personalized recommendations.

Can unloader braces really reduce knee joint pain? + –

Yes. Unloader braces shift weight away from the most worn part of the knee, relieving stress on damaged cartilage. This offloading effect often decreases pain, improves mobility, and helps preserve any remaining healthy cartilage in the joint.

Which unloader or offloader knee brace works best for plus-size people with osteoarthritis? + –

Look for a brace featuring wraparound straps and adjustable offloading settings to accommodate larger thighs or calves. A model like the Brace Align Plus Size KoAlign Osteoarthritis Knee Brace redistributes weight away from damaged compartments while ensuring a snug, secure fit for plus-size users.

Can I still stay active with knee arthritis? + –

Absolutely. Low-impact activities—such as walking, cycling, or gentle swimming—support joint health without excessive stress. Wearing a knee brace can further reduce pain and enhance stability, so you feel more confident and stay active longer.
