Founded as DonJoy in 1978 by Mark Nordquist, the Philadelphia Eagles' offensive line captain, and Ken Reed, a local lawyer, the company started out designing and producing simple sleeves made of sewn-together neoprene that were pulled over the knee, ankle, and elbow joints for support. Over the years, with massive medical research and development and exceptional technological innovation, DJO Global has grown in orthopedics and orthopedic rehabilitation, offering over one thousand medical devices that help people throughout the entire continuum of care, from injury prevention to rehabilitation. The DonJoy brand can be seen every day at the elite level of sports, with bracing, compression, and protective solutions in the training rooms and on every field of play. Top athletes, trainers and sports physicians have all come to trust DonJoy. DONJOY PERFORMANCE IN ACTION DONJOY ADVANTAGE IN ACTION Product Description The DonJoy Deluxe Hinged knee brace is designed for moderate stability and support for knee ligament meniscus injuries, sprains and osteoarthritis. The bilateral hinges to help provide additional knee support. The Drytex material is an alternative to neoprene and constructed of a unique nylon core and polyester lycra fabric that allows for improved airflow. This fabric provides compression and support, yet allows for breathability. The popliteal is located behind the knee. Individuals that do a lot of bending can experience friction burn from the material rubbing, so choosing an open back or open popliteal prevents that discomfort. The DonJoy Deluxe Hinged knee brace is ideal for those who have allergies or irritations to neoprene or live in warm weather climates. This brace is suitable for use in water. If it is submerged in salt water or chlorinated water, it should be rinsed off afterward with fresh water and allowed to air dry.
