What could a knee that clicks be symptom of?

There are many potential causes of a knee that clicks. Some of the most common include:

* Meniscal tear: This is a tear in the cartilage of the knee. Meniscal tears can be caused by sudden twisting or turning movements, or they can develop gradually over time.

* Patellofemoral pain syndrome: This is a condition in which the kneecap (patella) does not track properly over the thigh bone (femur). Patellofemoral pain syndrome can be caused by a variety of factors, including muscle weakness, tight muscles, or a structural abnormality of the knee.

* IT band syndrome: This is a condition in which the iliotibial band (IT band), a thick band of tissue that runs from the hip to the shin, becomes inflamed. IT band syndrome can be caused by overuse, such as running or cycling too much.

* Arthritis: This is a condition in which the cartilage that lines the joints wears away. Arthritis can be caused by a variety of factors, including age, obesity, and certain medical conditions.

* Baker's cyst: This is a fluid-filled sac that forms behind the knee. Baker's cysts are often associated with other knee conditions, such as arthritis.

If you are experiencing a clicking knee, it is important to see a doctor to determine the cause and get proper treatment.
