Cycling for a period of time, sometimes hear riders complain about knee pain after heavy riding, in fact, this is due to improper riding style caused by knee meniscus injury.

The meniscus of the knee joint is a fibrocartilaginous tissue with a thick circumferential edge and a thin inner edge in the shape of a wedge, which is called a meniscus when viewed from the plane; it fills the space between the femoral and tibial condyles and has the function of enhancing 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.

Several situations that are more likely to cause injury.

1. The direction of force when riding is inconsistent with the foot and pedals. A good number of people tend to ride with both knees inward or outward, so that the direction of the foot is not consistent with the direction of force, which is likely to cause strain injury in the long run, and the smaller the angle between the thigh and calf, the easier it is to cause problems, and the sudden speed up in this state is also more likely to cause trauma. Because most people in the fleet did not lock the pedal, so the posture can not be forced to correct, only everyone can consciously correct.
2. Sudden force to speed when the thigh muscle strength did not keep up. When the muscles are highly fatigued (without cramps), if the muscle strength of the thighs can not be brought up, the whole body weight plus the original pressure will be all over the knee, I tried once, the knee quickly swell up, practice flexion can not, but in the application of drugs and do not do a small amount of slowly subside swelling. I heard that a long-term situation like this can cause fluid retention.
3. Long-term low frequency riding. Many people will think that low-frequency riding can make the power better, but the chance of injury to both knees back than high frequency is much greater.
4. Too much climbing exercises and sprint exercises.
5. The saddle height is too high or too low.
6. Excessive weighted squat exercises. Strength exercises should be gradual, at once to too much weight will make the knee injury.
7. The knee injury is not treated in a timely manner.
8. Incorrect warm-up exercises. Do some warm-up exercises related to the knee for a long time, such as bending knee rotation. This action will wear out the meniscus and is not advocated.
