Many people complain about knee swelling. After all, do not forget that it is on the knee joint that the main load falls during walking. Swelling and pain can be caused by completely different reasons, from injuries to infectious diseases.
Swollen knee due to injury

As a rule, the injury is accompanied by a sharp pain, the intensity of which may weaken, as well as the presence of hematoma and edema.

- displaced patella;
- dislocation of the knee joint.
It is worth noting that the knee swells with each of the above injuries. Therefore, the victim must be immediately sent to the hospital - without medical assistance herehardly manageable.
Why does the knee swell? Most Common Diseases
Sometimes it happens that swelling of the knee joint appears against the background of general he alth without mechanical injuries. Of course, such a phenomenon can signal a host of various diseases:
- Bursitis is a fairly common disease, accompanied by inflammation of the synovial bags (burs). The inflammatory process can be caused by trauma, stroke, constant physical exertion, as well as infection. Athletes, in particular cyclists, jumpers, football players, most often face a similar problem. The disease is accompanied by pain, fever and fluid accumulation inside the joint.
- If the knee is reddened and swollen, this may indicate the development of arthritis. Such a disease can occur under the influence of various factors, including trauma, infection, hypothermia, exercise, etc.
- In some cases, edema can be explained by the presence of free bodies in the cavity of the joint bag. Such a phenomenon can be the result of both trauma (for example, a meniscus rupture or fracture), and some diseases, including osteoarthritis, chondromatosis. In any case, the patient needs help, since the presence of free bodies is often accompanied by blockade of the knee joint.
- If the knee is swollen from the inside, then this may indicate the so-called "Baker's cyst", which is nothing more than an accumulation of fluid inpopliteal region.
