Why does only one of my knees pop?

This type of popping symptom is often a sign of a meniscus tear or a loose piece of cartilage within the joint. 1 These are tissues inside the knee that help cushion and protect the joint. The torn meniscus or loose cartilage may catch in the knee as it moves back and forth. This causes a popping sensation.

Why does my knee make a noise when I straighten it?

The popping sound usually comes from air seeping into the soft tissue, finding its way into the area around the joint and causing tiny bubbles in the synovial fluid. When a person bends or stretches their knees, the bubbles can burst with a popping or cracking sound. This may sound alarming, but it is usually harmless.

What does it mean when you bend your knee and it clicks?

The noise occurs because tiny air bubbles (nitrogen) accumulate within the fluid inside your joints and when you move, they collapse (or burst) due to the changes in pressure inside the joint. The noise occurs when the gas bubbles collapse. When the bubbles burst this is called ‘cavitation’.

When I straighten my leg my knee clicks?

That can mean the presence of noises, including clicking when you straighten your leg. Specific causes can include crepitus, which is a term for pops that occur due to buildup of gas in joints such as the knee, as well as tightness associated with runner’s knee and other repetitive stress injuries.

Is it bad if your knee pops every time you bend it?

There’s probably no reason for concern. Popping and cracking sounds usually aren’t signs that something’s wrong. “A lot of joints crack and the knees are a really common joint to crack,” says David McAllister, MD, director of the UCLA’s Sports Medicine Program.
