‘Take a Load Off’ - Clinical evidence into the effectiveness of osteoarthritic knee bracing | June 2007

Results of studies into OA knee bracing, using DonJoy’s ‘OA Braces’, published in ‘The Journal of Bone & Joint Surgery1  demonstrated conclusively that the principle of offloading knee brace technology used on patients displaying symptomatic unicompartmental OA under in vivo, dynamic weight-bearing conditions, was successful in providing separation of the medial femoral condyle from the tibial plateau, thus avoiding excessive loads on the degenerated compartment.

Two of the OA Adjuster’s key features are DonJoy’s own pioneering ‘Lock and off-Load Technology™’ that shifts compressive knee joint forces from the degenerative area to the healthy compartment; and the ‘4 Points of Leverage™’ system that provides ligament stability.

DJO has long been associated with cutting edge innovation through scientific and medical research.  The company’s commitment to R&D can be seen at its unique Clinical Education & Research Facility (CERF) Lab in California, where virtually any open or arthroscopic orthopaedic surgical procedure can be recreated or performed in the lab, making CERF an invaluable educational tool and resource for all levels of practicing health care professionals. Clinicians and researchers alike annually perform a wide variety of both invasive and non-invasive surgical procedures.  The facility is frequently utilised by orthopaedic surgeons from across the globe for surgical skills training and the development of new or innovative orthopaedic surgical techniques.

The OA Adjuster underwent rigorous testing in DJO’s own Biomechanics Lab, resulting in a unique brace that is suitable for ligament instabilities and post operative rehabilitation for sufferers of moderate to severe unicompartmental OA.
