A knee brace is a supportive device worn around the knee to provide stability and reduce pain. It is commonly used by individuals recovering from injuries, such as ligament tears or fractures, and can also help those with chronic conditions like arthritis. Knee braces come in various types, including hinged, compression, and sleeve styles, each designed for specific needs. These braces can be made from materials like neoprene or elastic, offering varying levels of support and comfort. They are often recommended by healthcare professionals, such as physiotherapists or orthopedic surgeons, to aid in rehabilitation and improve mobility during physical activities.
