We have all felt a sudden click, pop, or snap sound from our knees while standing or picking something off the floor. While it may seem like a premature aging sign, that’s often not the case. These knee pops are a common joint occurrence known as crepitus, a medical term for the crackling or grinding noise that can occur during joint movement. This condition is not exclusive to seniors. In fact, a recent global review shared by Arthritis Research Canada found that knee crepitus is experienced by 41% of the general population.
Although it’s normal, if you hear this popping sound frequently, it may be a cause for concern. But why does it happen? Read this blog to explore the top three reasons behind knee popping and clicking, and how to fix knee popping.
Is It Normal for Your Knees to Pop?
Yes, most of the time, knee clicking when straightening the leg or bending it is completely normal. In fact, according to a study shared by Arthritis Research Canada, approximately 36% of people experienced knee popping with no knee pain. However, if the occurrence is frequent, accompanied by swelling or pain, it could indicate deeper issues. So, while it is common and often harmless, crepitus is not always something to ignore.
The same study showed that up to 81% of people with knee osteoarthritis report these sounds, and it may be linked to underlying changes in joint structure, including early osteoarthritis. So, while occasionally clicking in the knee is not alarming, it is important to pay attention if it occurs frequently, becomes painful, or limits movement.
What Causes Clicking in the Knee?
If you’re wondering, “Why is my knee popping with every step?” here are some common reasons behind it. Understanding the possible causes can help you know when to seek care and when it’s just normal joint movement:
Air Bubbles Bursting in the Joint
Knee joints are lubricated by a fluid called synovial fluid, which occasionally forms tiny air bubbles. When you do squats or stand up, the pressure on your joints changes, causing the bubbles or gas to collapse suddenly, resulting in a pop or crackling sound. This phenomenon is also known as cavitation, which occurs when you crack your knuckles. These noises are harmless and do not cause any damage to joint structures.
Tendon or Ligament Movement
Tendons or ligaments, such as the iliotibial (IT) band or patellar tendon, often glide over bony structures or scar tissue, causing a clicking/popping in the knee. This sound is common during repetitive movements, such as walking upstairs or running. In fact, these noises are especially normal among individuals with active lifestyles.
Cartilage Surface Irregularities & Patellar Tracking
Irregularities in the cartilage surface and patellar tracking are among the common causes of knee crepitus. This occurs when the joint surfaces, particularly under the kneecap, do not glide smoothly due to worn cartilage. As a result, people may feel grinding, crunching, or popping sensations in their knees. This is often associated with patellofemoral pain syndrome, commonly known as runner’s knee. However, if you experience a loud pop in the knee, followed by pain during activity or prolonged sitting, it may indicate early cartilage deterioration. In such cases, physiotherapy for knee pain can help manage symptoms and improve joint function.
How Do You Know If Your Knee Popping Is Serious?
Knee crepitus is characterized by common joint noises, often harmless and not a sign of damage. Most people experience it without any pain or loss of function. However, sometimes crepitus may signal a more serious condition. Here are some important warning signs to watch out for:
- Pain and swelling
- Loud pop in the knee, followed by pain
- Locking or catching sensation
If you are experiencing any of these symptoms, early intervention, including physiotherapy for knee pain, can reduce symptoms and protect your knee from further joint damage.
Does Physiotherapy for Knee Pain Help Knee Clicking with Pain?
Yes, physiotherapy can be highly beneficial for managing knee clicking. Muscle imbalances, early cartilage wear, and poor joint alignment often cause knee crepitus. All of these issues can be addressed through early intervention with physiotherapy. Here are some of its benefits:
Strengthens Knee-Supporting Muscles
Weak muscles around the knees can result in poor joint mechanics. With the help of expert physiotherapists in Winnipeg, these muscle groups can be strengthened. Through guided exercises, these experts help improve joint stability and reduce unnecessary pressure on the kneecap. In the long run, this can significantly ease pain and prevent the recurrence of crepitus during movement.
Corrects Patellar Tracking Issues
Improper patella movement is a common cause of knee clicking. Physiotherapy for knee pain and crepitus includes targeted mobility and strengthening exercises that help the patella or kneecap glide more smoothly. This reduces joint friction and minimizes the grinding or popping sounds that often occur due to patellofemoral pain syndrome.

Improves Range of Motion and Flexibility
With stretching routines and joint mobilizations, expert physiotherapists in Winnipeg help restore flexibility and range of motion. These hands-on techniques lead to smoother joint function and reduced resistance during movement, particularly during activities such as climbing stairs, squatting, and prolonged sitting.
Supports Long-Term Joint Health
People with early signs of osteoarthritis often experience knee clicking with pain, which can be effectively managed through physical therapy. Improving muscular support helps slow the progress of joint degradation. With regular therapy sessions, you will not only manage current symptoms but also support long-term joint health, preventing future damage.
Conclusion
While occasional knee clicking is normal, it is essential to be aware of signs such as pain, swelling, or frequent clicking/popping in the knee. These may indicate an underlying condition that should not be overlooked. Even minor discomfort, if neglected, can lead to more serious complications over time, so early evaluation is key.
