The knee is one of the largest joints in the body. Since it is used too much during the day, the possibility of injury and injury is also high.
The location and severity of knee pain vary depending on the cause of the pain. Some other symptoms that accompany knee pain include swelling and stiffness, redness, warmth to the touch, a crackling sound, locking or inability to fully straighten the knee. Most minor aches respond well to self-care measures. On the other hand, depending on what the problem is, your array may also need an interventional procedure.
Pain is important warning us that something is not right in our body. . For example, if we have knee pain due to reasons such as falling or hitting, the cause of the pain is obvious to us. Whether the reason is known or not, it will be the best decision to consult a doctor for knee pain that does not stop and disrupts daily life. Below you can find common causes of knee pain and how the pain occurs depending on the structure of the knee. However, let us remind you from the beginning that there may be reasons outside the list here.
Injuries can affect the ligaments, tendons, fluid-filled sacs called bursae, bones, or cartilage that surround the knee joint. The most common knee injuries that cause knee pain can be listed as follows:
Patellar (Kneecap) Tendinitis
Patellar tendonitis is the inflammation of one or more tendons. Tendons are thick, filamentous cords that connect bones and muscles. Inflammation of the patellar tendon, which connects the muscles of the front of the upper leg to the shinbone, is more common in runners, skiers, and cyclists. One of the symptoms of this inflammation is knee pain.
The meniscus tissue consists of durable, rubbery cartilage and acts as a shock absorber between the shinbone and thighbone. If a sudden turn is made while putting weight on the knee, it may tear. Meniscus tear is mostly seen in football players and those who are involved in other sports where the knee is heavily weighted. On the other hand, it can happen to anyone who strains the knee and gets a hard blow to the knee. Pain, swelling and limitation of movement are among the symptoms of locking in the knee.
Some knee injuries cause inflammation of the bursae (sacs that surround the joint bone) in the knee. Thanks to these vesicles, tendons and ligaments glide smoothly over the joint. Knee bursitis has symptoms such as pain, redness, swelling and limitation of movement.
Locking that restricts knee movement may be caused by cartilage tear. When part of the torn cartilage slides into the knee joint, it is difficult to keep the knee straight.
Osteoarthritis (Joint Calcification)
Osteoarthritis, also known as calcification, occurs over the years due to wear on the joints and deterioration of the articular cartilages. It is a non-inflammatory rheumatic disease. Damage to the cartilage causes pain. It can have different causes such as weight problems, injuries, joint diseases, family history of arthritis or muscle weakness. It is more common in later ages, due to aging. When it comes to calcification, keeping the knee immobile for a long time or, on the contrary, moving the knee too much increases the pain. Generally, the pain starts gradually and continues to increase over time. Sometimes sudden attacks of pain may also occur. Joint stiffness and swelling may occur. Patients have difficulty in bending and fully extending the knee. Joint range of motion is reduced. After a long period of inactivity, complaints of pain and swelling usually increase more.
Walking, squatting and climbing stairs are the movements that trigger and increase the pain the most. pain is expressed in the form of weakness in the joint and an internal pain. Patients sometimes state that they hear a sound or a crackling sensation along with locking and pain in the knee.
In the joint examination, the localization of the pain and the amount of joint range of motion are taken into account. In radiological examinations, if possible, comparative direct x-rays of both knees are sufficient for diagnosis. If necessary, the physician may request an MRI examination of the knee in order to determine the amount of cartilage loss and to obtain more information about the condition of the meniscus and ligaments.
Inflammatory rheumatic diseases (such as gout, Behçet's syndrome, familial Mediterranean fever) can be seen at almost any age and affect not only the joints but the whole body. Diseases in this group are related to immune system disorder. In inflammatory rheumatic diseases, pain can affect all joints of the body, including the knees. The pain lasts for days and may be accompanied by symptoms such as swelling, limitation of movement, weakness, loss of appetite.
It is a painful complaint that mostly affects young people who are growing up and interested in sports. A slight pain is felt in the knee during rest. The pain becomes sharper when the knee is moved. In any case, the situation itself is caused by directory overuse. There is tenderness and swelling in the area under the kneecap.
Chondromalacia patella (Runner Array)
In this condition, the pain is in the front of the knee and usually creates a squeaking sensation as the knee is extended forward. Sitting for long hours by bending the knee, going up and down stairs, kneeling, squatting further increases the pain. This can occur due to excessive use of the knee, where the knee is constantly subjected to stress, such as running. At the same time, bad alignment of the foot and knee bones or a knee blow can also cause this discomfort. Physical therapy is usually recommended.
Treatment of chronic knee pain due to gonatrosis (as a result of calcification):
