Knee osteoarthritis: what you need to know

Knee osteoarthritis is more than just a sore joint—it’s a progressive condition that can seriously impact your quality of life.

So what’s going on inside your knee when arthritis sets in?

The breakdown beneath the surface

It all starts with cartilage, the smooth, rubbery tissue that cushions your bones.

Over time, this protective layer wears down.

Without it, bones begin to rub together—causing pain, stiffness, and swelling that can make even simple movements feel like a struggle.

Common symptoms to watch for

If you’re experiencing any of these signs, your knees might be trying to tell you something:

• Persistent pain and swelling
• Stiffness, especially after sitting or resting
• Reduced range of motion, making it harder to bend or straighten your leg
• A feeling that your knee might ‘give way’ or buckle

Knee osteoarthritis is incredibly common in Australia.

In 2022, around 2.1 million Australians—roughly 8.3% of the population—were living with osteoarthritis, and the knee is the most frequently affected joint.

Who’s most at risk?

Certain groups are more likely to develop knee arthritis:

• Women
• People over 55
• Those with a history of knee injuries

How physiotherapy can help
