Overview
DonJoy’s premiere custom knee brace for active patients with osteoarthritis just got better.
Extremely lightweight, the OA Defiance® PRO provides durable support for moderate to severe levels of osteoarthritis. The bilateral hinge bars offer support for ligament instabilities and work in conjunction with a patented telescoping condyle pad which puts the load control in the hands of the patient. Ideally suited for patients with active lifestyles or athletes.
1 — Less than 20oz
Custom carbon fiber frame is built tough
3 — Swiveling internally mounted straps
Swiveling straps create 100% contact and contour to the anatomy to grab the calf better which allows for removal of the anti-migration band and improved ease of application.
5 — Memory foam condyle pads
Memory foam condyle pads help provide even pressure on the OA offloading side and are great for all skin types.
2 — New C-6 liner material
C-6 Liner that is soft to the skin and provides moisture wicking and anti-microbial.
4 — New low-profile design
Lower profile design with internally mounted straps providing a more intimate fit.
6 — New soft touch strap ends
Soft touch strap ends offer flexibility to form better to the leg while maintaining a secure closure.

Fource Point Hinge
FourcePoint hinge increases flexion angles, reducing anterior shear forces and strain on the ACL and thus significantly decreasing the chance of injury.6,7,8,9
- Helps keep both knees out of the at risk position6,8,9
- NO significant performance limitations6
- Improves joint mechanics of both knees post ACL surgery6,9
4-Points-of-Leverage
- Helps decrease ACL strain by at least 50%1,2,3
- Significantly reduces tibial rotation vs unbraced and sleeved groups
- Increases patient confidence after ACL reconstruction
1 — Anterior thigh anchor
3 — Anterior tibia strap
Applies an active constant load to prevent anterior tibial translation
2 — Posterior tibia anchor
4 — Anterior tibia strap
Applies an active constant load to prevent anterior tibial translation
OA Technology
3-Point Offloading
We mechanically shift weight away From the damaged part of the knee to help address four common relief Points for those suffering from OA*
Every DonJoy® OA knee brace can off-load either the medial or lateral compartment and incorporate load adjustment mechanisms that allow patients to fine tune their brace to meet their daily needs.
Pain
Pain caused from OA of the knee can create barriers to motion both psychological and physical. Addressing immediate pain issues is essential to getting active.
Alignment
If the body’s alignment is not correct, it can create wear on joints that can cause pain. Incorrect alignment can be natural, can come from an injury or can be the result of the body compensating for pain.
Strength
As knee pain increases, the body compensates to avoid the pain. Quadriceps stop firing and more pressure is put on joints exacerbating the situation. Maintaining strength in key muscle groups is critical to reversing the path of degeneration and getting back in motion.
Instability
Instability can be real, whether from injury or from OA, and it can also be perceived, as when sharp pain creates the impression of instability. Real or perceived, instability can be a barrier to motion.
