The left knee is obviously uncomfortable when bent, what s going on?

You press on the upper tibial tubercle below the knee, and if it hurts, it may be an anterior tibial tubercle injury or tibial tuberosity osteochondritis.

Adolescents (including young adults) are susceptible to tibial tuberosity osteochondritis, located in the upper tibial tubercle below the knee, caused by collision injuries and frequent stretching of the tubercles by strenuous exercise of the muscles and ligaments. Athletic teenagers are prone to this phenomenon... Manifestations include exertional pain (getting up, jumping, climbing stairs), squatting pain, pressing pain, tuberoscopic bulge, etc.

The method is also simple and the only way, is to keep two or three months to half a year do not exercise vigorously, generally can heal itself, if you are now if there is no bulge, it means that it has just appeared, you must pay attention to rest for two or three months do not exercise, do not play ball games, especially football and basketball, do not jump or bruise again. If you continue to exercise, you may have to wait until the end of puberty to heal the epiphysis will not be painful, and even in adulthood, it will still hurt if you exercise too much, the key is that the bulge will not disappear, which may affect the image and convenience of life. In short, the problem is very common and not big.,It's just that exercise will hurt.,If it doesn't hurt badly, it doesn't affect life very much.。。

By the way, the anterior tibial tuberosity is the attachment point of the quadriceps tendon, and the force is very large and this point is very small, and the child's epiphysis is not healed, so it is easy to hurt.

You can ask questions, hope:).

Sports injuries, I used to be like this, the cartilage between the joints is damaged, don't exercise hard, have time to take more steps, this action will inject joint lubrication into the knee. Feet more than ten centimeters apart, do a very slow squat, legs trembling to indicate that there is an effect. It works especially well when you sit with both hands on the inside and outside of your knees!

Don't exercise, it will cause your legs to not be straight'It's ugly, and it's even worse when you're old.

I know why because you are similar to me ... Tell you that it was your ligament that was injured. You must rest and recuperate、、Yes, it is better to buy some safflower oil to wipe it、

5. When the upper end of the tibia is violently impacted or the knee joint is injured by rotation or hyperextension due to indirect violence, it will cause knee dislocation, resulting in knee pain and inability to bend. In severe posterior dislocation, it can cause popliteal artery, venous rupture, embolism, compression, limb necrosis and ischemic contracture.

Suggestion: If the knee joint has been violently impacted or indirectly violent, and then the knee pain cannot be bent, it is necessary to consider whether the knee joint has been dislocated, and should go to the hospital in time accompanied by family or friends. After knee dislocation, it is often possible to achieve satisfactory restoration by manipulative closed reduction.

6. Malomalacia of the patella may also cause symptoms of knee pain and inability to bend.

Patellomalacia can occur at any age, but is more common in athletes and middle-aged and older women. In the early stage, adolescents present with anterior knee pain, which improves after rest, and with the prolongation of the course of the disease, the pain lasts more than is relieved, and the aggravated person when going downstairs is Kaizhong, and in severe cases, it is often necessary to go down the stairs sideways, and when going downstairs or walking, the knee joint is afraid of cold, and the knee joint can be repeatedly swollen and effusion, which is often misdiagnosed as "rheumatism".

When the disease is further aggravated, it is difficult to squat, and it is painful at night, which affects sleep and normal life. In the late stage, due to severe wear, the knee joint cannot be fully straightened, and hydroarthropsis and loose bodies may appear in the joint cavity, resulting in intra-articular locking and sudden jamming of the joint.

Suggestion: There are congenital and acquired causes of patellar malacia, the acquired causes are mainly related to labor, exercise posture and intensity, etc., when the knee joint is in a 35° 50° semi-flexed knee position, it will significantly increase the patellar subluxation or lateral tilt, so as to aggravate the lateral wear and tear of the patellofemoral joint, such as cycling, climbing, skating, etc., is a common cause of this disease. Once you know about it, you should try to avoid these situations.

1. Aseptic inflammation of the knee joint, such as synovitis, aseptic inflammation is not the same as throat inflammation. Throat inflammation may be a bacterial infection and needs to be treated with antibiotics such as cephalosporin and penicillin**. Aseptic inflammation of the knee joint is often triggered by cold, involvement, trauma or overactivity.

2. The more common is osteoarthritis, just like wrinkles and gray hair, which belongs to the aging and degeneration of joints. As the cartilage and ligaments in the joints wear out, they may be painful when they bend.

3. Meniscus injuries are sometimes caused by trauma, and sometimes by degeneration.

The specific analysis of what causes the pain when the knee joint is flexed must be combined with face-to-face clinical physical examination, supplemented by objective imaging examination for comprehensive judgment and specific analysis.

It is considered to be poor local circulation of the knee joint, local cold due to circulatory disorders, and it is not excluded that it is caused by joint pathology and arthritis. You can take Shujin Huoxue Tablets, Fenpide Capsules, Zhengqingfeng Tingning Tablets, or Oral Glucosamine Hydrochloride Capsules**. At the same time, try to apply local and moist analgesic ointment, and arrange life reasonably to avoid various adverse factors that are easy to cause the onset of osteoarthritis.

Many people will have this situation in their daily life, that is, the phenomenon of pain when the knee is bent, and many people do not know much about this phenomenon.

1.Method 1: You press the upper tibial tubercle below the knee, if it hurts, it may be a pre-tibial tubercle injury or tibial tuberosity osteochondritis.

2.Method 2: It is to keep two or three months to half a year do not exercise vigorously, generally can heal itself, if you do not have a bulge now, it means that it has just appeared, you must pay attention to rest for two or three months and do not exercise.

3.Method 3: The anterior tibial tuberosity is the attachment point of the quadriceps tendon, the force is very large and this point is very small, and the child's epiphysis is not healed, so it is easy to hurt The conclusion is that if the knee hurts here, you still don't need to insist on exercising, it is best to go to the hospital to see.

Precautions. There are many different causes of knee bending pain, but the most important thing is to take it into account your own situation**.
