"Recently, my knee is not feeling well."
"I feel something wrong behind my knee"
"I find it difficult to walk"
Do you have such concerns?
The knee joint consists of the thigh bone, the femur, the tibia in the shin, the fibula that supports the tibia, and the patella, which is generally called "Osara", and is surrounded by a joint capsule.
The knee is a joint that not only supports weight, but also performs intense and complex movements such as sitting and running.
In addition, since the bones of the knee joint are shallowly joined, the meniscus, ligaments, and surrounding muscles enable stable movement.
Most people don't usually pay much attention to the movement of their knees, but knee injuries can affect their daily lives in various ways.
In this way, our knees play a very important role in our daily lives.
In this article, we will take a look at the specific diseases that cause pain behind the knee.
I would appreciate it if you could understand the cause of your knee pain and give me a little peace of mind.

Diseases that cause pain behind the knee
knee osteoarthritis
One of the most common types of knee pain is osteoarthritis of the knee.
It is a disease in which the articular cartilage, which acts as a cushion to soften the impact of the knee joint, wears away and the synovial membrane within the knee joint becomes inflamed.
Many of the causes are deterioration of joint tissue due to aging, but there are various other triggers and factors such as obesity, past trauma, and bacterial invasion.
Osteoarthritis of the knee is a disease in which the symptoms gradually worsen over a long period of time, rather than a sudden worsening of symptoms.
"I feel somewhat uncomfortable."
"I feel like I can't move more than before."
Dealing with such awareness without leaving it as it is will be the point to prevent deterioration.
knee sprain
A knee sprain is an injury to a joint that does not show abnormalities on X-rays, among injuries that occur when the bones move beyond the normal range due to a large force applied to the knee joint.
The main symptoms are joint swelling and pain.
It is important to see a doctor as soon as possible, even if you do not have many symptoms, because the part that is difficult to feel pain may be damaged.
Knee joint sprains are not only for those who play sports,It is a disease that can occur due to the burden on the knee joint.
It can be said that one of the important points from the viewpoint of prevention is to learn how to deal with contact while being careful about injuries on a daily basis.
ligament injury
Ligament injuries are damage to the ligaments of the knee caused by a car accident or sports.
The ligaments of the knee are divided into the medial collateral ligament, the lateral collateral ligament, the anterior cruciate ligament, and the posterior cruciate ligament.
Excessive force applied to each ligament can lead to injury.
Initial symptoms may include knee pain, inability to move the knee, and swelling.
It is important to check for knee pain when receiving a strong external stimulus such as a traffic accident or sports.
Symptoms may appear later, so it is important to pay attention to the initial symptoms and respond quickly.
rheumatoid arthritis
Rheumatoid arthritis is not a disease caused by aging or obesity like osteoarthritis of the knee, but a disease related to abnormalities of the immune system.
Immunity is a system that attacks and eliminates harmful foreign substances such as bacteria and viruses that have invaded the body.
In rheumatoid arthritis, the immune system mistakenly recognizes its own normal cells as external and attacks them, causing inflammation in the joints, and the misidentification continues, leading to long-term inflammation.
Rheumatoid arthritis is a disease that affects joints throughout the body, not just the knees.
At the time of onset, it develops from relatively small joints such as fingers, wrists, elbows, etc., and gradually spreads to the whole body.
Symptoms also appear in large joints such as the knee.
Rheumatoid arthritis is a disease that progresses gradually before subjective symptoms appear.
It is often difficult to notice the initial symptoms, but when you wake up in the morning, your fingers, stiffness, and difficulty in moving your hands are key points to assess the symptoms.
Summary: When the back of the knee hurts
This time I explained the disease that causes when the back of the knee hurts.
Knees are body parts that are essential for us to live our daily lives.
"Stand" "Walk" "Squat" "Sit" "Run"
Knees are always used in daily activities that we do casually.
In other words, knee problems can threaten our daily lives.
Knees play an essential role in our daily lives.
When there is pain or discomfort, it is important to deal with it as soon as you notice it, without leaving it as it is.
It is also known that in any disease, treating the initial symptoms increases the therapeutic effect.
If you have any concerns, no matter how trivial, please do not hesitate to consult a medical institution.
We hope that this article will help you live a richer and healthier life.
