After riding for a period of time, I sometimes heard riders complaining about knee pain after intensive riding. In fact, this is due to improper riding caused by knee meniscus injury.
The meniscus of the knee is a fibrous cartilage tissue, which is wedge-shaped with a thick peripheral edge and a thin inner edge. When viewed from a plane, it is called a meniscus; it is filled between the femoral condyle and the tibial condyle, which can enhance the stability of the knee joint . The structural and functional characteristics of the meniscus determine that it is one of the most vulnerable tissues in the knee joint.
Following a brief explanation, 8 kinds of situations that are more likely to cause injuries:
1. The direction of the force when riding is inconsistent with the feet and pedals.

2. The thigh muscle strength did not keep up when the force was suddenly increased.
When the muscles are highly fatigued (without cramps), the force is exerted. If the muscle strength of the thigh cannot be lifted up, the entire body weight and the original pressure will completely overwhelm the knee. I tried it once, and the knee is very fast Swollen, knee flexion is not allowed, but slowly swelling after applying medicine and doing a small amount of walking. I heard that such a situation for a long time will cause water accumulation.

3. Long-term low-frequency riding.
Many people think that low frequency riding can make the strength better, but the chance of knee injury is much greater than high frequency.
4. Excessive climbing practice.

5. The height of the cushion is too high or too low.
6. Excessive weight-bearing squats.
Strength training should be done step by step. Excessive weight will hurt the knee.
7. The knee injury was not treated in time.

8. Incorrect warm-up exercise.
Do some warm-up exercises related to the knee for a long time, such as knee flexion. This action wears the meniscus and is not recommended.
