How is the pain behind the knee?

This can be seen from many problems of knee ligaments and cartilage. Walking and running like this will cause tension and tightness in the knees and cause injuries. Why? In the simplest way, the way the knee moves is not just a plane movement like a hinge. But there will be a slight rotation when moving. For example, when you walk, pay attention to your kneecap. If it moves vertically up and down without shaking back and forth, the pressure on your knee is very small, but if your kneecap moves in a figure-of-eight or S shape (viewed from the side), it may cause knee injury. The adjustment of good walking posture is very important. 1. Symptoms: A sharp and stinging sensation appears on a ligament outside your knee and thigh. Feel it and connect it to the outside of your knee. It is used to fix and connect the muscles outside your thigh with your knee joint. This is a complex structure, including two joints and three tendons ... when your leg is straightened during the step, this ligament will rub the cartilage on the outside of your knee. O-shaped legs, splayed feet, wide pelvis, varus knees (the knees will be inward when stepping on or walking, or even colliding) and flat feet are prone to such problems. Treatment: This is a rare knee problem. You need to reduce the strength of knee extension, which can reduce the friction between ligament and cartilage. In addition to ice compress, stretching the lateral thigh ligament will also help. 2, symptoms: pain behind the kneecap caused by going up and down stairs or ramps, and the tenderness point is on the kneecap. Diagnosis: Treatment of thigh and kneecap pain syndrome: Walking is not helpful to this symptom, so long-distance and heavy-duty walking should be avoided. Doing proper recovery training and strengthening the strength of your rectus femoris (the muscle located in the middle of the thigh, which is an important key to fixing the kneecap) will help to avoid the aggravation of this annoying symptom. I think this is one of the most common symptoms. 3. Symptoms: There is an intima on the edge of the kneecap inside the knee, and 70% of people have this useless trace organ. Some people will cause friction between this membrane and the kneecap when walking, usually because the knee is too bent and forced or the external figure is eight. Diagnosis: Treatment of inflammation of intermediate ligament: ice compress, massage, straightening knees as far as possible, and changing the posture of external image. Some serious cases require surgical removal of the dura mater. 4. Symptoms: There is obvious pain in the thick ligament under the kneecap, which is often called "spring knee injury", because people with this kind of injury usually exercise more than the ligament load when they start exercising again in early spring. Too much weight training, or not keeping your knees warm, may also cause the same problem. Diagnosis: Treatment of knee tendinitis: After five minutes of ice application, massage along the ligament direction and repeat several times. In addition, electrotherapy or ultrasonic therapy is also quite effective. 5. Symptoms: Injury to the hamstring muscle at the back of the knee is usually due to overexertion or leg stretching. Diagnosis: Treatment of goose foot bursitis: ice compress, rest and stretching. Adjust walking strength and posture. 6, symptoms: the central hamstring muscle pain at the back of the knee is usually due to the strength and posture of walking, so that the knee and muscles are tired for a long time. Diagnosis: treatment of tendinitis: ice compress reduces walking time and intensity.
