Knee pain is a common pain, and it usually appears as a result of cartilage damage, or it may be due to a specific trauma to the knee, or due to a sports injury.
Consultant orthopedic and fracture surgery, and knee arthroscopy, fellow of the Royal College of Surgeons in Britain, Dr. Nabil Fadel Rajab tells us about 7 of the most important causes of knee pain, he says at the beginning:
The knee is the joint that connects the thigh with the leg, and it is the largest joint in the human body knee It has two joints, a joint between the thigh bone and the tibia, and another joint between the thigh bone and the patella. Soft cartilage covers the surfaces of these bones that make up the joint, ensuring ease of movement.
The knee can be easily injured, because it is one of the most complex joints in the body. The knee consists of the junction of four bones, four ligaments, several tendons, two menisci, and cartilage.
Regarding the causes of knee pain, Dr. Nabil says, “There are a variety of causes of internal knee pain; many of them can be linked to injury due to some accidents such as falling, hitting a hard object, sports injuries or increased activity.
Adults, especially those over 60, are more likely to experience knee pain. However, internal knee pain can also occur in children and adolescents.”
Dr. Nabil lists 7 possible causes of internal knee pain as follows:
Osteoarthritis is a degenerative disease that causes cartilage to break down, causing bones to stick together jointsIf you experience internal knee pain while putting pressure on your joint, such as walking up and down stairs or sitting in a chair, a bone density test is necessary.
2. Rheumatoid arthritis
Rheumatoid arthritis is an autoimmune disease that can also cause internal knee pain caused by arthritis, so people with rheumatoid arthritis may experience severe knee pain in the morning, with symptoms decreasing throughout the day.
3. Injury to the medial collateral ligament
The medial collateral ligament runs along the outside of the inner knee to stabilize the joint. If the ligament is stretched too much, you may have a sprain. The collateral ligament can also be partially or completely torn. Injury to the medial collateral ligament most commonly occurs after pressure on the outer knee, as in contact sports.
Symptoms of a medial collateral ligament injury are: swelling, instability while standing or walking, a feeling of stiffness and a crackling sound at the time of impact.
4. Meniscus injury
Articular cartilage is cartilage that provides a cushion between the bones in a joint. There are two types of meniscus in each knee. They act as cushions between the thigh and tibia bones, and the meniscus can be torn or damaged if you try to twist or apply pressure to your knee; It is most common during sports or sports activities.
As for the symptoms of a meniscus tear injury, they are: a clicking sensation, swelling and stiffness, pain; Especially when you twist or rotate your knee or straighten the knee, and a feeling of instability in the knee.
A bursa is a small fluid-filled sac that helps reduce friction between joints. The bursa is located in the knees between the medial collateral ligament and three other tendons: sartorius, gracilis and semitendinosus. Together they are called pes anserinus. If the bursa becomes overused or irritated, it may produce extra fluid that causes swelling and pressure on the knee. This is known as pes anserine bursitis.
6. Cartilage rupture
This strong, flexible fabric covers the inside and outside of the knee. When the meniscus tears, it’s called a meniscus tear, and it’s a fairly common injury that can be repaired with surgery.
7. Knee contusion
If you suffer a direct blow to your knee, such as hitting an object or a hard fall, you may bruise your knee bone. This is also known as a knee contusion. A knee bruise can cause internal pain in the knee, depending on the location of the injury. Other symptoms of knee bruising include (skin bruising, swelling, and trouble bending the knee).
Dr. says. Nabil Fadel Rajab Knee injuries are fairly common, and to avoid knee problems, the following must be done:
Do exercises that work to strengthen the muscles, to support your knee.
Avoid falling or putting excessive pressure on the knee.
Maintaining weight, while avoiding excessive weight or excessive thinness.
Avoid activity that causes pain.
The doctor suggests some home remedies, most notably:
Use crutches to take the weight off the knee.
Apply ice to the affected area three or four times a day for 20 minutes at a time.
Wrap the knee with an elastic compression bandage.
Put pillows under the knee to raise it to the same level or higher than the level of the heart.
Take non-steroidal anti-inflammatory drugs such as ibuprofen (Advil) to reduce swelling.
If symptoms persist after three days, despite the application of these treatments, or if the pain worsens, it is necessary to speak to a specialist.
