Knee flexion hurts, what to do when knee bends pain

It should be infintellar bursitis.

Overview. It is more common in young adults, manual laborers, or athletes. It is mostly caused by repeated and frequent extension and flexion of the knee joint, with a slow onset and no obvious history of trauma.

Local dissection. There are actually three inferior patellar bursa. (1) The deep infrapatellar capsule, located in front of the patellar ligament and tibia, between the inferior pole of the infrapatellar fat pad.

ii) Subpatellar subcutaneous sac, located at the upper border of the tibial tuberosity between the patellar ligament and **. (3) Tibial tuberosity subcutaneous sac, located between tibial tuberosity and **.

These three bursal fluids are near the insertion point of the patellar ligament, which is very easy to be confused when diagnosing **, and the lesions are collectively referred to as hypopatellar bursitis, in order to accurately diagnose and treat this disease, its anatomical location must be clearly distinguished, and it is easy to misdiagnose and mistreat if it is confused.

**Pathology. Although the positions of these three bursas are different, the damage mechanism is roughly the same, which is mostly caused by repeated and frequent extension and flexion activities for a long time. Due to long-term knee extension and flexion activities, the patellar ligament and the upper end of the tibia have repeated frictional movements, resulting in chronic damage to the synovial sac, thickening of the synovial sac wall, fibrosis and atresia, so that the synovial fluid can not be discharged, the bursa itself is distended, and the patellar ligament and the upper end of the tibia can not get lubricating fluid, resulting in swelling pain and discomfort, which makes the knee joint extension and flexion unfavorable.

This disease is non-surgical**, which is often difficult to achieve, and surgical excision under local anesthesia is usually used. However, after resection, the patellar ligament and the upper tibia lose lubrication, and the extension and flexion of the knee joint is affected due to the tendency to retain scar tissue after surgery.

Clinical symptoms. Vague pain and discomfort in the knee subpatella, poor knee extension and flexion, difficulty in descending stairs, reluctance to straighten the lower limb on the affected side, mild claudication when walking, such as excessive extension and flexion of the lower limbs, causing aggravated pain. The patellar ligament is slightly raised near the insertion point compared to the unaffected side.

Diagnosis. Has a history of long-term strain in knee extension and flexion activities.

Tibial tuberosity or slightly upper border pain with slight tenderness.

There is a cyst below the patellar ligament and a fluctuating sensation.

In this case, it is recommended to go to the hospital to take an X-ray. According to your description, it's a bit like an osteochondroma. But to be sure, let's take a ** look at what I said.

Synovitis; Find out; Send us your details.

Check whether the cervical and lumbar spine are normal

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.

Empirical steps: Method 1: You press the upper tibial tubercle below the knee, if it hurts, it may be an anterior tibial tubercle injury or tibial tuberosity osteochondritis.

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.

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 reasons for the pain caused by knee bending, and the most important thing is to combine it with your own situation**.
