ACL Technology
We study body mechanics and listen to athletes. We consult physicians and push the envelope of technological innovation. Our braces combine the most advanced technology, strongest materials and highest craftsmanship. Of course, all of our knee ligament braces are constructed for excellent medial support to aid MCL and LCL indications.
Flexion Angle at Landing
The anterior shear force applied on the tibia was reduced by 9% for females and 13% for males6,9
The decrease in anterior shear force on the tibia should substantially reduce the load on the ACL6,8,9
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.
Customize your Brace
Make it your own with custom hinge options, accessories & colors.
FourcePoint ACL
This patented hinge design helps protect the ACL by incorporating a dampening mechanism in the last 25° of extension to help keep the knee out of the at risk position and increase the posterior tibial load.
FourcePoint Plus
The Plus hinge provides ACL protection benefits of the FourcePoint hinge with a reinforced steel outer plate ideally suited for the rigors of high-impact or collision sports.
OA Adjustable Hinge
The custom OA frame offers 1 to 7 degrees of off-load. The telescoping hinge helps provide additional off-loading up to 3 degrees. The memory foam condyle pads are included for increased patient comfort and compliance.
Standard Low-Profile Hinge
The polycentric hinge stabilizes the knee while matching natural knee kinematics. Polycentric hinges also maximize the anterior/posterior and varus/valgus stabilizing forces of the brace. This can used for ACL, PCL, combined instability, MCL, or LCL indications.
