Defiance Pro Custom Knee Brace
The DonJoy Defiance Pro is a custom-made functional knee brace with a carbon fiber frame, built for athletes and active individuals who need ligament support during demanding activity. Each brace is manufactured to the individual's measurements. It supports ACL, MCL, LCL, and combined instabilities, and its low-profile carbon fiber frame keeps the brace light and slim for comfort and freedom of movement.
The frame weighs under 20 oz (567 g) and sits 5 mm lower in profile than the Defiance Classic. Internally mounted swiveling straps fit closely around the anatomy to improve comfort and reduce migration, while the C-6 liner is soft, moisture-wicking, and antimicrobial. Silicone condyle pads help hold the brace securely in place. It can be ordered with a choice of hinges and a wide range of frame colors and accessories.
How It Works
The Defiance Pro is available with DonJoy's Four-Points-of-Leverage strapping system. According to the manufacturer, the FourcePoint hinge incorporates a dampening mechanism through the last portion of extension, which is designed to help keep the knee out of the at-risk position and reduce strain on the ACL. Hinge options let the brace be tailored to the type of instability and level of activity.
Hinge Options
- Standard low-profile hinge — polycentric hinge that matches natural knee movement; suitable for ACL, PCL, combined instability, MCL, or LCL indications
- FourcePoint ACL — patented hinge with a dampening mechanism in the last 25° of extension, designed to help protect the ACL
- FourcePoint Plus — FourcePoint benefits with a reinforced steel outer plate, suited to high-impact or collision sports
- OA Adjustable — custom osteoarthritis frame offering 1–7° of off-load, with a telescoping hinge for up to 3° more; includes memory foam condyle pads
Indications
- ACL instability
- MCL and LCL instability
- PCL instability
- Combined instabilities
- Osteoarthritis of the knee (with the OA Adjustable hinge)
Consult a healthcare professional to confirm the Defiance Pro and hinge option are appropriate for your condition and to complete the custom fitting.
