The human body is an amazing and universal mechanism. The joints of the arms and legs ensure the normal functioning of the limbs. Especially it is necessary to highlight the knee joints, with the help of which the legs are unbent and bent. Unfortunately, many of us experience knee pain when flexing. Here, the most important thing is to understand everything, because there are a lot of reasons for which there are pains in the knee joint. With minor pain in the knee, hasty conclusions should not be made. It can be due to age, that is, the fact that over time changes occur in the joint: the working surface is abraded and the volume of inter-articular fluid is significantly reduced.
Minor knee pain is one thing, but if the pain is sharp and systematic, it is best to protect yourself and consult a specialist. Indeed, severe pain in the knees can be signs of serious pathologies and diseases. Self-medication is not the best option. The fact is that the knee is the most complex joint in the human body. In its structure, this is a rather vulnerable mechanism, which is subjected to tremendous physical exertion daily. Knee mobility is ensured by strong leg muscles. If the knee does not function fully, then the flexion and extension of the legs is in question. When you are tormented by knee pain during extension, the main causes may be damaged tendons, ligaments or menisci. A very dangerous disease is arthritis, which inflames the knee joints. Let's dwell in more detail on the causes that cause pain in the knee when bent.
The pain in the knee joint itself can be explained only by finding out its cause. Unfortunately, there are many circumstances under which knee pain can occur during flexion. A banal bruise or an old leg injury can be felt after many years. In injuries, partial or complete rupture of the ligaments most often occurs.
The most common disease of the knee joint, according to statistics, is meniscus damage. Often, a person who has never experienced any pain in the knees may be attacked under the name “knee blockade”. If you have a chronic subluxation of the knee, pain in the knee joint cannot be avoided. This is just the beginning of the list of causes that cause knee pain when bent.
Move on. Have you noticed that your knee turns red, swells, hurts when they touch it? These are the first signs of bursitis. The main cause of the disease is inflammation, which affects the periarticular bag. It contains the fluid washing the joint. It happens that there is excess fluid in the joint cavity. This is caused by inflammation of the inner lining of the joint.
The leader among diseases of the knee joint, of course, is arthritis with all its manifestations. Hundreds of thousands of people of various age categories suffer from this ailment. The main signs are swelling, redness of the joint. The peak of pain falls at night.
Surely you noticed that some people hear a crunch when walking or running. This is the cause of arthrosis. This disease is in no way associated with arthritis, but is a wear of the intraarticular cartilage. The form of severe arthritis is gout. Due to impaired circulation, pain of the same degree of intensity in both knees is quite possible. This is especially evident when the weather changes.
Unfortunately, there is no one universal way to treat all of the above diseases of the knee joint. In each case, it is necessary to accurately determine the cause. This is achieved by various research methods. They mainly do x-rays, computed tomography, MRI and arthroscopy. The main thing to remember is that with recently started knee pains, you should immediately consult a doctor who will identify the cause and prescribe a course of treatment. Otherwise, the disease will go into the chronic stage, in which no one will give 100% guarantees of recovery.
