What causes pain under the knee?

Very many people, and maybe most, experience periodic pain under one or the other knee. Why does the knee ache? Basically, such problems arise as a result of playing sports, overloads associated with work or household duties.

The knee is the largest joint in the human body. The bones of the knee joint (knee) are divided into two discs, called menisci. The connection of the bones of the lower leg and the femur is carried out by means of muscles, ligaments and tendons. Inside the joint, the bones are covered with articular cartilage. It is with his help that shock absorption occurs, and for movement a smooth, sliding surface is created.

Pathologies that may cause pain in this area

Sometimes it hurts under the knee due to injuries to various knee structures. In particular, we are talking about cartilage and tendons, periarticular bags and so on. In addition, patients are often worried about not only the pain under the knee, but also the limitation of mobility, joint stiffness. Also, the joint can swell and increase in volume. Pain under the knee in conjunction with the above signs indicates that the patient has inflammation of the knee joint - arthritis.

Acute sudden damage. It is a trauma that usually provokes pain under the knee. Most often it can be caused by acute sudden damage. There are such damages, for example, with abnormal twisting, falling or bending of the knee joint. In this case, pain under the knee, as well as swelling and bruising can be strongly pronounced, developing after getting injured within a few minutes.

Overloads lead to such damages:

• Bursits. These are inflammation of the articular bags.
• Tendinitis - inflammation of the tendons.
• Syndrome of fibrinous film, in which articular ligaments appear thickening, folds.
• Pain under the knee, in the anterior part of it, resulting from overloads, overweight, and trauma.

In some cases, pain under the knee may be caused by problems in other parts of the body. For example, it can be nerve compression.
