Knee sleeves are designed to protect the knee from future injury or risk of damage. This protection is especially important for knees that are under great daily pressure (running, jumping, weightlifting).
Knee sleeves also add a valuable compression element that increases blood flow and reduces pain, not only during workouts but also after the performance. The reason this compression aspect is so important because a compressed knee encourages blood flow through the blood vessels of the knee.
Orthopedic doctors suggest wearing knee sleeves pre and post-surgery as it helps to reduce swelling around the injury. Knee sleeves help an individual through rehabilitation exercises and leisure day-to-day activities by reducing pain, swelling, and stiffness.
