The knee joint is one of the most complex and largest joints in the human body, with a very large range of motion and the greatest pressure. Therefore, the knee joint is easily damaged accordingly, for example, after too long exercise, the knee joint will appear sore.
But with proper rest, this discomfort will soon ease. There are also some people in the daily life, the knee joint always makes a "clicking" sound, what is going on? Is it caused by joint degeneration?
Why does the knee joint make a clicking sound?
1. Physiological joints bounce
The cause of the "clicking" sound in the knee joint is not necessarily related to joint degeneration. If there is no other discomfort at the time of the sound, then it is a physiological joint bounce, which is due to a slight collision between the patella and the femur.
Especially when bending the knee joint, it is possible that this relatively crisp sound may occur, so this phenomenon does not need to be treated.
2. Caused by disease factors
If there is a "clicking" sound in the joint area, it will also be accompanied by some other discomfort, such as pain and swelling in the knee joint, redness and swelling around the area, increased skin temperature, and limited mobility, which is generally caused by some knee joint disease factors.
For example, this can be caused by meniscal injuries, as well as when patellomalacia and various osteoarthritis occur. With the increase of age, for some elderly people, a series of degeneration of cartilage will occur.
Then, when the knee joint is bent, it will make a "clicking" sound, accompanied by repeated pain and discomfort in the knee joint.
It can be seen that the cause of "click" in the knee joint, in addition to being related to physiological factors, has a very important relationship with pathological factors.
Therefore, in daily life, any group of people should pay attention to the protection of the knee area. Below, teach you a few small movements, which can play a role in protecting the knees.
