Knees are one of the joints in the body that goes through the most pressure throughout our lifetimes. It’s so common that about one-third of all Americans experience knee pain at some time or another. Not only do our knees feel pain, but they also can get pretty noisy. Hearing sounds like popping or crunching may or may not be an issue. It’s important to be able to recognize when the noises become issues that need to be checked out by a professional. Here are some of the causes of noisy knees:

Air Bubbles

Just like the sound that comes from cracking your knuckles, these popping noises are caused by air bubbles trapped in the synovial fluid around the joint. The bubbles typically burst when you bend or stretch the joint and cause a popping noise, which is usually harmless and nothing to be concerned about.

Injured Joints

If you recently had a hard fall or got into an accident, the noises might be caused by scar tissue, a meniscus tear, or a tendon moving around the knee. These types of injuries should be treated promptly so that you can save yourself from further complications.

Runner’s Knee

Runner’s knee is a very common term used to describe an umbrella of conditions that cause pain around the kneecap. It can be caused by a variety of everyday activities like walking, climbing, or kneeling. Many times, it can also be caused by improper running form or excessive training. Aside from pain in your kneecap, this can cause a grinding or clicking sound when you extend or bend your knee.


According to the Arthritis Foundation, one in two adults will develop symptoms of knee osteoarthritis during their lives – making it the most common chronic condition of the joints. It’s pretty much when your cartilage breaks down and the bones in the joint lose their lubrication, causing a grinding or scraping sensation in the knee. This causes a clicking or popping when the knee moves. Some of the most common risk factors of osteoarthritis are obesity, age, previous injury, and genetics. If not treated properly, cartilage will break down and the bones will start rubbing against each other causing joint damage and intense pain.
