You might have heard a popping, cracking or clicking sound while getting up, sitting down, climbing a flight of stairs or walking. The medical terminology for these sounds is crepitus. It is pretty common, and anyone might experience it. But you might ponder about the reasons for knee popping.
The build-up of pockets of gases like nitrogen or carbon dioxide or air might be the causes of knee cracking sound. The bubbles of these gases or air accumulate in the synovial fluid in the knee joint. When these bubbles burst, it makes a popping sound. The synovial fluid is a lubricant between ligaments, tendons and bones, making the knee movements smooth. Another reason for the cracking sound in your knee is the tissues in the knee rubbing together.
The sounds of popping and cracking in the knee while walking or climbing stairs are not really out of the ordinary. But if along with these sounds, you start having knee pains, then it might be an indication towards other orthopaedic issues like,
- Torn tendons or tendonitis,
- Cartilage or Meniscus tear,
- Ruptured ligament.
In case of pain, the causes of knee clicking might vary significantly. So you might want to have a proper consultation with a concerned doctor, as you could be diagnosed with a condition mentioned above.
Symptoms Of Knee Popping
In typical cases, there are no other symptoms associated with the knee popping. As discussed earlier, the most common knee cracking sound reason is the burst of gas bubbles in the knee joint due to the frequent movement. However, here are a few musculoskeletal-related symptoms,
- Musculoskeletal-related Symptoms:
- Stiff and painful joints.
