The purpose of tying the knee is mainly that there is some pain in the left leg patella recently. It may be the pain of quadriceps tendon and patellar ligament. In order to prevent injury and strengthen the fixation and protection of the knee, it is decided to use the knee strap when squatting heavily.

Because the purpose is to protect the knee joint, because it is moderately elastic and not tightly wrapped. Winding from the upper part of the patella to the lower part of the patella, about five and a half times. After binding, it feels good and won't feel too tight. It's really helpful to start using it when you squat down to 80% weight. The pressure on the knee joint when squatting is obviously less than that when not wrapped. Maybe it will affect your knees after being wrapped.

That is to say, in the case of squat load, it is best to use knee binding.
