Right knee injury caused by piercing shoes.

I haven't played ball for more than three weeks. But my right knee hurts inexplicably, probably in the patella depression and ligament connection point of the knee, not in the left knee joint where the operation was performed.

During this time, I found that I have been walking in hole shoes. When you walk, your legs are often trembling or weak. When I switched to sneakers or sneakers, I found that there was no such phenomenon. Later, my knee pain also improved. It can be inferred that shoes with holes have great hidden dangers.

1 Because there is sweat on the soles of the feet, it will slide in the feet, causing instability.

When walking, the injured knee joint has great bearing capacity because the whole shoe palm is soft and unsupported. It wears out every time you walk.

Cartilage inflammation surged, and the required stability of knee joint was lost.

Therefore, it is suggested that students with knee injuries should not wear hole shoes, but should wear flat shoes or hard-soled sports shoes with relatively stable soles, so as to reduce the secondary injury to the knee joint. The principle is roughly the same as squatting shoes, providing lower limb stability.

Of course, knee injuries can be ignored.
