Knee Cracking and Popping

Do your knees make crackling or popping sounds when you move? If so, you may be experiencing knee crepitus. While knee crepitus is often harmless, it can be a cause for concern in some cases. In this blog post, we will delve into what knee crepitus is, its possible causes, and when it’s appropriate to seek the expertise of a physiotherapist.

Knee crepitus refers to the sensation or sound of grinding, popping, or crackling in the knee joint during movement. This condition can be categorized into two types: benign crepitus and pathological crepitus.

Benign crepitus is generally harmless and commonly associated with age-related changes in the knee joint. It may be accompanied by mild discomfort but does not usually cause significant pain or functional limitations.

It can occur when:

  • Cartilage surfaces of the knee rub against each other
  • Air pockets are released within the joint
  • Tendons or ligaments snap over each other
  • Synovial fluid flows through the knee

Knee CrepitusOn the other hand, pathological crepitus can indicate an underlying issue, such as joint inflammation, cartilage damage, meniscus or bony loose bodies, requiring appropriate medical attention.

So when should we go to see a physiotherapist about our noisy knees? While knee crepitus can be a normal occurrence, there are situations where seeking the guidance of a physiotherapist is advisable:

  • Persistent pain or swelling: If your knee crepitus is accompanied by persistent pain, swelling, or a feeling of instability, it’s important to consult a physiotherapist. They can assess the underlying causes, provide a proper diagnosis, and recommend appropriate treatment strategies.
  • Limited range of motion: If you notice a decrease in your knee’s range of motion or experience difficulty in performing daily activities, a physiotherapist can help identify any muscular imbalances, joint restrictions, or other factors contributing to these limitations.
  • Functional limitations: If knee crepitus affects your ability to engage in sports, exercise, or perform your regular activities, a physiotherapist can provide specific exercises, stretches, and rehabilitation techniques to improve knee function and reduce discomfort.
  • Previous knee injuries: If you have a history of knee injuries, surgeries, or conditions such as osteoarthritis, a physiotherapist can assess your knee’s overall health, address any underlying issues, and develop a tailored treatment plan to manage symptoms effectively.
  • Lifestyle modifications: If knee crepitus affects your overall quality of life or limits your participation in activities you enjoy, a physiotherapist can offer guidance on lifestyle modifications, joint protection techniques, and assistive devices to minimize discomfort and maximize function.

Remember, it’s important to consult a healthcare professional if you have concerns about knee crepitus, especially if it is accompanied by pain, swelling, or functional limitations. They can provide a comprehensive evaluation, recommend appropriate treatment options, and help you regain optimal knee health. Don’t let noisy knees hinder your daily activities—seek professional advice to keep your knees healthy and pain-free.
