Have you got an audible clicking at your knee, and you’re wondering…
“Why does my knee keep clicking?”
Maybe it clicks every time you squat. Maybe it pops when you go for a walk. Or perhaps it’s been doing it for years, and you’ve started wondering if every click means you’re damaging your knee.
The good news is this:
In most cases, a clicking knee isn’t causing damage.
But that doesn’t mean it should be ignored. As it does mean the knee is not working right.
Let’s look at why knees click, when it’s something to pay attention to, and what you can do to improve it.
Why Does My Knee Click When I Walk?
There are several reasons your knee may click while walking or bending.
Sometimes it’s simply gas bubbles moving inside the joint. Other times, it’s tendons or ligaments moving over nearby structures.
But one of the most common reasons we see in people with ongoing knee pain is the kneecap not moving as smoothly as it should.
Rather than gliding neatly through its groove, the kneecap can shift slightly before snapping back into position, creating that familiar click.
Can a Meniscus Tear Cause Knee Clicking?
The meniscus is a shock-absorbing piece of cartilage that sits between your thigh bone and shin bone. Whilst a meniscus injury is more linked to the knee locking up, it does not cause clicking, but clicking can be present alongside a meniscus injury.
When it’s injured, clicking is often most noticeable during bending movements. And it can also feel like the knee is locking up.
What’s interesting is that some people continue to experience knee clicking even after meniscus repair surgery.
Why?
Because repairing the meniscus doesn’t automatically restore the way the knee moves.
If the knee continues to load unevenly, or the movement patterns haven’t changed, the clicking can still be there even though the meniscus has been repaired.
That’s why successful recovery isn’t just about healing tissue—it’s also about improving how the whole knee functions.
Your Kneecap Is Designed to Stay in One Place
Think of your kneecap (patella) like a train travelling along a railway track.
There’s a groove at the end of your thigh bone that’s designed to keep the kneecap sitting snugly in the middle as your knee bends and straightens.
When everything is working well, the kneecap glides smoothly.
You don’t notice it. You don’t hear it. You don’t think about it.
So Why Does the Kneecap Click?
When the knee isn’t moving efficiently, the kneecap can drift slightly out of alignment as you bend your knee.
Instead of staying centred, it slides a little to one side before moving back into its groove.
That small movement can create the click you hear.
This is especially common if you’ve had:
- A previous knee injury
- Weakness or poor muscle control around the hip or knee
- Ongoing knee pain
- Changes in the way you walk or squat because you’ve been protecting the knee
The click isn’t usually the problem.
It’s a clue that the joint isn’t moving as efficiently as it could.
Is the Clicking Damaging My Knee?
The clicking itself is often not causing damage in the short term. But left unchecked it can often contribute to wear and tear of the knee cap (patella).
However, the click may be telling us something important.
If the kneecap is repeatedly moving out of its ideal position, it’s a sign that the joint isn’t being loaded as well as it should be.
Over time, continuing to overload the knee in poor positions may increase irritation to the structures around the joint and potentially contribute to further wear or injury.
How do you improve clicking?
A knee brace that supports the knee cap position can help sometimes. Even taping up the knee can relieve the clicking temporarily.
When the kneecap stays more centred, it often moves more smoothly—and the clicking can reduce almost immediately.
This is why braces and taping can be useful in the short term.
They can improve comfort, increase confidence and make movement feel easier.
But they don’t fix the underlying cause.
Once the brace comes off, the kneecap will usually return to moving the way it always has unless the movement pattern itself has changed.
How Do You Fix Knee Clicking Long-Term?
The long-term goal isn’t simply to stop the noise.
It’s to improve the way your knee moves.
That means improving the biomechanics of how your body loads the knee, especially during bending movements like walking, climbing stairs and squatting.
When excessive pressure through the knee is reduced:
- The joint has more space to move naturally.
- The kneecap stays better aligned in its groove.
- The quadriceps tendon glides more smoothly over the front of the knee.
- The muscles around the hip and knee work together more efficiently.
- Bending movements become smoother and more comfortable.
As the knee starts moving the way it was designed to, the clicking often becomes less noticeable—and in many cases disappears altogether.
Rather than forcing the kneecap into position, the aim is to create the right environment so it naturally stays there.
The Bottom Line
If you’ve been wondering, “Why does my knee click when I walk?”, remember this:
The sound itself is usually not the problem.
More often, it’s a sign that the knee isn’t moving or loading as efficiently as it could.
Whether the clicking started after a meniscus injury, continues after surgery, or has gradually developed over time, improving the way your knee moves is the key.
