Popping and Clicking Joints: Normal or a Problem?

A knee that cracks when you stand up from a chair, or a shoulder that pops when you reach overhead, can be alarming the first time you notice it. Most of the time, this noise, called crepitus, is completely normal and nothing to worry about. But there are situations where popping and clicking are early warning signs of a joint problem that deserves attention.

Patients throughout Claremont and the Inland Empire ask our team about joint noises often, so here is how to tell the difference between harmless crepitus and something that warrants an evaluation.

It helps to think of joint noise less as a diagnosis on its own and more as one piece of information. The same crack or click can mean nothing in one person and something meaningful in another, depending entirely on what other symptoms come with it.

Joint noise tends to draw outsized attention because it is so noticeable compared to other, quieter signs of joint wear. A joint that is genuinely struggling often gives off far more subtle clues, like mild stiffness in the morning or slight swelling after activity, that are easy to overlook while the audible pop or click grabs all the attention.

Patients frequently arrive at our Claremont office describing years of harmless knee popping alongside a brand new, unrelated complaint that turns out to be the actual reason for their visit, which speaks to just how normal a bit of joint noise really is for most active adults over time.

Why Joints Pop and Click

Joints are surrounded by fluid-filled capsules that lubricate movement. When a joint is stretched or moved in certain ways, tiny gas bubbles within that fluid can collapse or shift, producing a popping sound similar to cracking your knuckles. This type of noise is generally painless and can happen repeatedly throughout the day without any lasting effect on the joint.

Clicking can also occur when a tendon or ligament slides slightly out of place and then snaps back over a bony prominence as the joint moves. This is common around the shoulder, hip, and knee and, again, is typically harmless when it does not come with pain.

Age-related changes in cartilage smoothness can also contribute to a grinding or crackling sensation, sometimes called crepitus in the strictest medical sense, without necessarily indicating active joint disease. Cartilage surfaces that are perfectly smooth in youth naturally develop small irregularities over time, and this alone can produce noise without pain.

When Popping and Clicking Are Normal

• The noise happens with movement but causes no pain
• There is no swelling, warmth, or visible change in the joint
• The joint moves through its full, normal range of motion
• The popping does not increase in frequency or intensity over time

If your joint noises fit this pattern, there is generally no need for treatment. Staying active, maintaining healthy muscle strength around the joint, and avoiding prolonged periods of stiffness, such as sitting for hours without moving, can help keep joints feeling their best.

Many patients worry that popping itself is wearing down the joint, but there is no strong evidence that painless crepitus accelerates cartilage damage. The noise is a byproduct of joint mechanics, not a cause of injury on its own.

When Joint Noise Signals a Problem

Crepitus becomes a more meaningful symptom when it is paired with pain, swelling, a sensation of the joint catching or locking, or a feeling of instability, as though the joint might give way. In the knee, for example, grinding or crunching accompanied by pain when climbing stairs can point to cartilage wear consistent with early osteoarthritis. A popping sensation at the moment of an injury, followed by swelling and pain, can indicate a ligament or meniscus tear that needs prompt evaluation.

Red Flags Worth a Same-Day Visit

• Popping that occurred during a specific injury, followed by swelling within hours
• A joint that locks or catches, making it hard to fully straighten or bend
• Pain that limits weight-bearing or use of the limb
• A visible change in the shape or alignment of the joint

How Orthopedic Specialists Evaluate Joint Noise

When you come in with concerning joint noise, your provider will start with a hands-on exam, checking range of motion, stability, and areas of tenderness. X-rays can reveal narrowing of the joint space consistent with arthritis, while an MRI provides a detailed look at cartilage, ligaments, and other soft tissue structures when a more specific diagnosis is needed. According to the American Academy of Orthopaedic Surgeons (AAOS), crepitus alone, without pain or other symptoms, is not considered a reliable sign of joint disease on its own, which is why the full clinical picture matters more than the sound itself.

Treatment, when needed, depends entirely on the underlying cause rather than the noise itself. Early arthritis might respond well to physical therapy and activity modification, while a suspected ligament or cartilage tear may require imaging and a more targeted treatment plan.

Simple Ways to Support Joint Health Day to Day

• Warm up before exercise and stretch afterward to keep surrounding muscles and tendons flexible
• Maintain a healthy body weight to reduce mechanical load on weight-bearing joints like the knees and hips
• Stay consistent with low-impact activities such as walking, swimming, or cycling, which nourish cartilage through gentle joint movement
• Avoid staying in one position, seated or standing, for hours at a time without moving

These habits will not necessarily make joint noise disappear entirely, since some crepitus is simply a normal feature of how your joints are built. What they can do is reduce the likelihood that painless noise ever progresses into something more significant.

The Bottom Line

A little popping and clicking is a normal part of how joints move and is rarely a cause for concern on its own. Pay attention to the company it keeps: pain, swelling, and instability are what turn a harmless noise into a symptom worth having checked out.

If you have been quietly worrying about a noisy knee or shoulder, a single visit can usually put your mind at ease one way or the other, and if there is a genuine issue, catching it early gives you far more treatment options than waiting until pain sets in.
