    • I'm going to ask my workcomp doc to get this for me tomorrow. Do you have any advice for me if they will not order it for me?

      Recovering from a 3rd acl surgery and 1st all surgery.
    • Thank you for contacting Don Joy Performance. As our performance line generally can not be covered by insurance, I would recommend looking at the Playmaker II with a Fourcepoint hinge. This is through our sister company at betterbraces.com, and is very comparable to the FullStop.
  • Mikey at 9/6/2016 6:54 PM
    • Had a full reconstruction 20 years ago. Leg is in great shape. Back in the 90's I had a very expensive DonJoy that needed to be custom fit to my leg for skiing. Recently got back into skiing and would love to buy something more over the counter without making a big deal of the purchase. Will the Bionic do the job?
    • Yes, this will definitely help if you're looking for something over the counter. Designed with dampening hinges to prevent hyperextension and help improve joint mechanics in both surgical and non-surgical knees. Through the dampening cycle of the hinge, muscle memory trains your body to keep both the braced and un-braced knees out of the "at risk" zone.
  • Jadyn at 9/4/2016 7:15 PM
    • Is there a way to adjust the brace so that my knee can be fully extended to 180 degrees. Thank you
    • Unfortunately no, there is no way to make adjustments in the hinge.
  • Alex at 8/19/2016 9:04 AM
    • I had ACL reconstruction and meniscus repair surgery in October 2015. I was cleared for full activity this July 2016. Will this brace provide the support I need for running and playing rugby? I got the full force prior to surgery but can't use that for play because of the aluminum parts. I just need the protection of hyperextension for play and making sure this will provide that. My knee is at full strength compared to my right leg.
    • Yes, The Bionic Fullstop Knee Brace uses hinge technology and a four-point leverage system to keep the knee out of the "At Risk" position.
  • Adrian at 7/7/2016 8:50 PM
    • I'm a high school defensive lineman and have ITBS on the right knee, would the bionic full stop brace be good for me
    • Yes, this brace should help. The hinge technology and four point leverage system helps to keep your knee out of the "at risk" position. It will help prevent hyperextension and can be worn during football.
  • Juan at 7/4/2016 11:15 AM

    • The BIONIC FULLSTOP KNEE BRACE is made of a perforated neoprene and mesh.

    • Hi, My left knee had an accident from basketball. ACL was rupture and reconstructed by surgery but my meniscus damaged too much then doctor need to remove it.
      I want to use for daily life and get back to play sport again ex. basketball, football, tennis, skiing.
      Which product is best for this case. Is this FullStop good for me?
    • The Bionic Fullstop Knee Brace would be a good choice for you. It provides you with stability and protection for the meniscus. The hinges prevent hyperextension, and helps to train your body to keep the knee out of the "at risk" position.
  • Jack at 4/25/2016 12:55 PM
    • Could insurance help pay for part of this brace?
    • We do not accept insurance only credit card
  • Michael at 4/19/2016 7:33 AM
    • I had ACL reconstruction last June. I have an older version of the playmaker brace but it slips off all the time. I just started playing basketball and football again, will this brace be better than the one I already have?
    • The DonJoy Performance Full Stop Brace is an ACL brace but also provides support to the MCL/LCL. The Fullstop hinge is designed to keep the knee out of the "At Risk" position and significantly reduce the risk of ACL injury. The Fullstop knee brace will provide more specific ACL support than the current brace you currently own. The Fullstop knee brace has silicone banding that helps eliminate slip.

    • I had a pretty bad lateral meniscus tear and a moderate ACL sprain. I had arthroscopic knee surgery to repair the torn meniscus. I play lacrosse and do weight training and I am unsure of what brace I should get.
    • We recommend the Bionic FullStop Brace for your ACL injury. The hinge on this brace will reduce the amount of strain on your ACL and significantly reduce the risk on injury by keeping your knee out of the "at risk" position.

    • I have Arthroscopic Surgery coming up from my Complex lateral meniscus, which I am trying to put of, in the mean time what is the best brace for me to workout in? What do the Bionic Full Stop Knee Brace do the trick?
    • For a meniscus tear the Bionic Knee Brace would be suffiiceint support while working out.
  • John at 3/23/2016 5:31 AM
    • I have been diagnosed with arthritis in my right knee, which results in pain more prevalent after activity. I ride and excise bike 5-6 times per week and engage in moderate weight training at least 4 times per week. What is the recommended bract to provide stability and control pain.
    • Perhaps the Webtech knee brace will be the suitable brace for you. The brace will offer mild support and will help to decrease pain in the front of the knee during activities. The brace is indicated for mild artritis and patellofemoral pain which is pain around the kneecap.

    • Which better after acl recons in terms of daily activitie and getting ready to play basketball (highly contact sports) the defiance or full force thx
    • Both are equally supportive although the Defiance is a better fit since is it custom. The Defiance is the premier brace
  • José Angel at 3/3/2016 11:16 PM
    • Where does this brace stan in relationship with the fullforce?? I have the fullforce, and it was way more expensive than this, which is better? which is more comfortable and allows better performance??

      Thank you!
    • The Full Force is reccommended after a complete rupture of the ACL and reconstruction surgery. The brace will provide more support than the FullStop brace especially with activities that require cutting and starting and stopping. The FullStop brace would be used of there was a partial tear of the ACL, years after reconstructive surgery and with daily activites
  • D L at 3/1/2016 3:34 PM
    • with the Bionic full stop is the brace right or left specific or will it fit on either knee
    • The Bionic Fullstop knee brace is universal and can be worn on either the right or left knee.

    Great brace - working very well

    Reviewed by:
    Verified Purchase
    I tore the meniscus in m knee in two places and after surgery, have been reluctant to do much for fear of re-injuring it. After a minor slip, I decided it was time to get a brace. Since then, I've been back to jogging and generally working out. I'm not yet back to my martial arts studies (which require a lot of pivoting on the foot), I plan to be back soon after regaining some strength and stamina. The braces fits very well and prevents my knee from going one way while my foot goes another. It's very comfortable so far (around an hour working out) but have not yet tested it on longer runs (I run half-marathons). I have confidence while running that I won't inadvertently twist my knee.
    Pros: It's easy to get on after the first few times - it seems to have stretched enough that it's easy to get on and off, but is not too loose or slack. At first, it was very tight and I though I might have to get the next larger size. But now, I'm glad I got the size I did because it fits very well.
    Cons: None so far.

I am very happy with the product, and I would surely recommend this.

    I was excited to have received the brace since my knee is milling me. The brace is long and suppose to provide good support, however it goes downward when I walked and just didn't stay in place. For a premium price, I expected to get a better product.
    Pros: Length is good for support if the product actually fit Good material Made beautifully
    Cons: Doesn't fit right Hot Didn't do the job

    Sturdy brace but sizing is wrong

    Reviewed by:

    I have extreme knee pain due to misalignment, I was very excited to have found this brace to stabilize my patella -- however, this is a pull on brace and sized too small, it was hard to pull on although I used the size chart and even went up a size. It seems like a good brace if the size was right. Too bad I have to return it.
    Pros: Sturdy support
    Cons: Sizing is wrong, difficult to pull on and off.

    Great quality and support

    Having suffered from a torn and repaired ACL many years ago - I still experience pain and vulnerability. I also have no cartiledge in both knees and have bad arthritis. In search of knee support beyond a sleeve but not as expensive as a custom brace - my search ultimately landed on the fullstop. Better Brace site offered an even lower discount then from the Donjoy site. The brace fits well, is easy to put on, and the best part is it doesn't slide down like many knee braces will. (Assure you measure and order the right size).
    Pros: Easy to put on, stylish, durable, easy to clean, and you feel the support.
    Cons: I would like to see better direction on how to put it on. When I first got it, I looked up a video but wasn't fully sure. I experienced one occurance where my knee did over extend which is what the brace is suppose to prevent, but I put the brace on sitting on the ground with my knee straight opposed to having the knee bent while putting it on. I am thinking this is the reason why.

    Completely tore my left ACL in Dec 2016 at an MMA striking seminar. Using regular braces my knee buckled twice doing high kicks after the tear. Discovered the ACL tear after an MRI late Jan 2017. Bough this brace Feb 3rd. This brace enabled me to get back to training and training hard! Foot jabs, rear leg kicks, double rear leg kicks... Strong and powerful with no problem. Please remember to tighten the straps. Forgot once and the knee slipped just enough to remind me. BTW I train 4 days a week (striking only since discovering the ACL tear.) Getting my ACL repaired with my hamstring April 18th. Thank you for an amazing brace. Worth every penny!
    Pros: I hope this helps others looking to postpone ACL surgery for a bit.
    Cons: I think the velcro should go all the way around above the knee to get the straps just a little tighter, but it is indeed tight enough.
