DJO Incorporated is a leading global provider of high-quality, orthopaedic devices, with a broad range of market leading products used for rehabilitation, pain management and physical therapy. They also develop, manufacture and distribute a broad range of surgical reconstructive implant products. They are the largest non-surgical orthopaedic rehabilitation device company in the United States and among the largest globally, as measured by revenues.

DJO Incorporated's beginnings are linked to professional sports. The company was founded in the Carlsbad, California garage of Philadelphia Eagles football player Mark Nordquist in 1978. Nordquist, who wrapped an old inner tube around his unstable knee for support, teamed up with two of his friends to explore the possibilities of neoprene. The first products for the company - then named simply DonJoy after two of the men's wives, Donna and Joy - were "knee sleeves" constructed from old neoprene wetsuits. This innovative concept attracted interest and the company soon embarked on a research and engineering programme that would advance the world of bracing.

In 1987, DonJoy was purchased by Smith & Nephew Inc. and ProCare was acquired in 1995. Then known as the Bracing and Support Systems division of Smith and Nephew, the company launched four top-of-the-line knee braces including the Defiance and Legend functional knee braces which put DonJoy on the map. The Defiance, designed for active adult and adolescent patients with moderate to severe knee ligament instabilities, became the company's flagship product. By completely customising the product to suit the patient's individual needs and providing a low profile, lightweight brace with a lifetime guarantee, top athletes could be confident in returning to their sport of choice. The Legend, meanwhile, became the top ‘patient-ready’ brace for active adults and adolescents. These key products served as a foundation that helped DonJoy tap its full potential as an orthopaedic products provider.
In 1999, Chase Capital Partners (CCP), Fairfield Chase Medical Partners and senior management acquired the company. Shortly after the acquisition, the company changed its name to ‘dj Orthopedics’ the first of many steps designed to expand and reposition the company within the sports medicine market.

In 2006 they introduced their regeneration range of products - bone growth stimulation devices that are used to treat non-union fractures. That year, they changed their name to DJO and completed their acquisition of Aircast, a leading global ankle brace, cold therapy and vascular system manufacturer based in the US. 

Our current business activities are the result of a combination of two companies with broad orthopedic product offerings in the United States and foreign countries. One of those companies, ReAble Therapeutics, Inc. (“ReAble”), was a leading manufacturer and distributor of electrotherapy products for pain therapy and rehabilitation, a broad range of clinical devices for the treatment of patients in physical therapy clinics, and a broad range of knee, hip and shoulder implant products. In 2006, ReAble was acquired by an affiliate of Blackstone Capital Partners V L.P . (“Blackstone”). The other company, DJO Opco Holdings, Inc. (“DJO Opco”), formerly named DJO Incorporated, was a leading manufacturer and distributor of orthopedic rehabilitation products, including rigid knee bracing, orthopedic soft goods, cold therapy systems, vascular systems and bone growth stimulation devices. On November 20, 2007, ReAble  merged with DJO Opco (the “DJO Merger”). ReAble then changed its name to DJO Incorporated (“DJO”) and continues to be owned primarily by affiliates of Blackstone.

DJO’s product ranges are sold in over 56 countries through wholly-owned subsidiaries or independent distributors, primarily in the USA, Europe, Canada, Australia and Japan.
