What's the difference between this brace and the regular Armor? I can't figure out why this one costs $50 more...
Question by: Al on Apr 2, 2010, 1:35 PM
The difference is due to the fact that this brace comes equipped with FourcePoint hinges.
The DonJoy FourcePoint Hinge protects the ACL. The FourcePoint Hinge enhances the DonJoy Four Points of Leverage system by damping knee joint extension, improving the brace's mechanical performance, and reducing knee shear forces. The FourcePoint Hinge utilizes a spring mechanism to apply a gradually increasing amount of resistance during knee extension. The resistance reduces the time spent near full extension, or in the at risk position, increases the posterior load applied by the brace on the tibia to prevent anterior tibial translation, and gives patients a more natural gait by applying progressive resistance before reaching a firm end point.
The resistance can start at flexion angles between 25° and 65° and engages during the last 25° of extension prior to coming to a hard stop. Five different resistance levels are available to meet rehab protocol specifications and provide comfort. The resistance can be adjusted using the supplied allen wrench to modify the set screw placement. The same wrench can be used to turn the resistance completely off by simply flipping a switch.
Because the hamstring insertion angle increases and the quadriceps become mechanically disadvantaged as the knee becomes more flexed, anterior shear forces on the tibia and ACL strain are reduced. Therefore, athletes returning to sport after an ACL reconstruction who wear a DonJoy ACL brace equipped with FourcePoint Hinges can protect themselves while engaging in activities involving the run-stop-jump task.

What's the difference between the standard and short calf lenght? Is it the same performance?
Question by: André on May 21, 2010, 5:48 PM
Standard calf: 16"
Short calf: 14"
(total length of brace)
A shorter calf on the DonJoy Armor is recommended for shorter individuals (under 5'7) and patients who ski or ride motocross. The length of the brace has no effect on the functionality of the brace.

I am 3 weeks out of ACL reconstructive surgery, and researching which brace might be best for me. My MCL was torn as well. I lead an active lifestyle, but my main concerns are walking rough, uneven terrain for my job. I also participate in watersports, some snow skiing, and coach fastpitch softball. Contact sports are a thing of the past for me. Any advice would be appreciated.

Hello Todd,
The Armor Knee Brace will definitely assist in the ACL recovery and support, as well as provide stability to the knee.
If contact sports are not a concern, a DonJoy Legend SE-4 Knee Brace (https://www.donjoystore.com/donjoy-legend-se-4-knee-brace-41) may be preferable to an Armor as the armor is typically used for athlete level protection..
If a rigid brace is not a requirement, we also have:
DonJoy Drytex Playmaker Wraparound/Sleeve
https://www.donjoystore.com/donjoy-drytex-playmaker-wraparound-sleeve
DonJoy Deluxe Hinged Knee

I ride motocross and have both LCL and MCL injuries due to hyper-extension and straight legged impact. I am looking for the best support from re-injury but to also minimize discomfort when riding, running, etc. Will the fource point hinge be too restrictive when riding my bike?
Question by: Phil Ingram on Jan 12, 2012, 10:25 AM
The Armor with FP hinges would be recommended to prevent hyperextension. The lbs. of pressure can be adjusted for functional purposes. Should you have any questions give us a call at 888-405-3251.

I tore my ACL a couple of years ago playing soccer and never had a reconstructive surgery. I got to the point where I am running 3-4 miles and doing plyometrics after he injury. I played some flag football yesterday for the first time since injury and had no brace on. The knee felt good sprinting and cutting but I feel a little irritation in knee today. I am now trying to get back into soccer but still a little scared and nervous. What knee brace would you recommend for playing soccer and contact sports with a torn ACL?
Thanks in advance.

Should this brace be able to handle sliding in baseball/softball? And also I ruptured my acl and I currently own this brace but was wondering if the fourcepoint hinges are good for this injury or should I disengage them so they act as a standard hinge? I wanted the fourcepoint so that after I have surgery which probably won't be until November, I could use it during my recovery as well.

The Armor with FP hinges would be the best product for your condition and activity level. The FP hinges are the only hinges clinically proven to protect the ACL specifically.

Hi,
I injured my medial meniscus in HS and have reaggravated it on several occasions over the last decade. I injured it again last week playing hockey when I took impact to the outside go my leg. I would like a brace that could give me support playing a physical sport like hockey while still giving me range of movement. I have never been diagnosed with acl or mcl tears. What knee brace do you recommend?
Thanks,
Aren

Hello, Aren -
The DonJoy Armor Knee Brace is the most highly recommended for high contact/collision activities such as hockey and football. Because you have medial meniscus injuries and no ACL or MCL involvement, you probably do not need this type of rigid frame brace. We would recommend the DonJoy Reaction as more of an appropriate choice.
https://www.donjoystore.com/donjoy-reaction-knee-brace
This would allow for minimal to no limitation in your range of motion and still provide appropriate support to your medial meniscus.
If you have further questions, please feel free to contact our product specialists at 888-405-3251.
Thank you and have a wonderful day!

I have had an ACL reconstruction and my meniscus was really bad so after. They recommended this brace and now that I have had it for a lot less than a year and have been playing in it. The straps are started to stretch and the padding is starting to get ruff and come apart. I was wandering if there was some kind of warranty for that sense it hasn't been that long.
