If a patient has a meniscus injury at the beginning of the meniscus or a recent meniscus injury, it is best to wear a knee brace or knee brace, or even a cast to protect the knee, in order to prevent the knee from being damaged again by external forces. If the meniscus is damaged for a long time without a brace, it is very easy to aggravate the damage to the meniscus, leading to more serious consequences. If the injury is prolonged, in order to protect the knee joint and not interfere with sports, it is recommended to wear a sports strapped meniscus knee brace, which is more supportive and has a stronger fixation effect, helping to protect the knee joint without interfering with normal sports, and is supported by an elastic support band or elastic strip on both sides, which can play a role in limiting excessive knee flexion and extension. In addition, sports knee braces are often used to keep the knee joint warm and prevent it from getting cold.
