    • 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
    • What this brace is made off? Please, thanks
    • The BIONIC FULLSTOP KNEE BRACE is made of a perforated neoprene and mesh.
  • spencer at 7/2/2016 3:56 PM
    • Can it be used in water like for swimming?
    • Yes, you can swim with the Bionic FullStop. Just make sure you rinse with clean fresh water after being used for swimming. Lay flat to air dry.

    • 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.
  • Jay at 3/29/2016 10:30 AM
    • 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.
  • Tog at 3/10/2016 9:31 AM
    • 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.

    A great brace

    Reviewed by:
    I used to have a Donjoy in the 90's, which was red/blue and had a sleeve. I loved this brace, but after time it wore down. I recently reinjured my knee and bought this brace. I feel it's a perfect fit and very reasonably priced.
    Pros: Fits well Patella hole material seems to be good
    Cons: It is a little warm, but that might be good for me. Time will tell.

    I purchased one of these braces a couple of years ago and it's still going strong. This is the best knee brace I've ever owned. I'm playing golf and other activities with no restrictions. Thanks DonJoy.
    Pros: Keeps my knee stable and is very well made.
    Cons: Don't have any complaints.

    Best fit for me

    Reviewed by:
    After many years of working in the Live entertainment industry my knees are no where near what they used to be. Should of listen to the old timers and stopped jumping off the stages.

    Purchased a pair of these for knee stability.

    Pros: I can wear them on both knees all day long while snowboarding without needing to adjust them at all. I'm experiencing a lot less fatigue after being on my board all day.
    Cons: The only negative I found as in all knee braces is a little discomfort at the end of the day from the material bunching up behind the knees.

    Good knee brace - Lack of customer support

    Reviewed by:
    Verified Purchase
    I bought the knee brace a few months ago. It's comfortable and seems to provide a good way to prevent hiperextension (the main reason why I'm using it). But, I find it difficult to ask for customer support to know if this knee brace is designed to be used in both knees at the same time. Would the braces touch each other? would it be comfortable? was the product design for this?
    Pros: Comfortable, good materials.
    Cons: Lack of easily accessible customer support.

    I was looking for a brace for partially torn ACL. Bought one with some doubt but came out the perfect choice. I play outdoor and indoor sports at competitive level and needed a brace which can protect my knee. This one does not slide down and adjustment needed only every 15-30 minutes since I don't wanted to straps to be very tight. Excellent choice.
    Pros: Stays on place for good amount of time while doing heavy sports activity. Perfect length which make is very comfortable. Quick adjustment with pulling from bottom within 3 seconds.
    Cons: Feels uncomfortable when wearing over couple of hours and need to open straps for a minute to feel comfortable.

    Good Brace depending on the activity

    Reviewed by:

    Full ACL replacement using the Patellar Tendon on March 9, 2017 after a high speed impact skiing. After 9 months of rehab to get back skiing ASAP this was the best brace option short of a full custom brace. I tested the brace trail hiking in the northeaster PA mountains when I received it in late December. The added stability & confidence gained was fantastic. After skiing in 4 -5 times now I found it to cause more problems than it was resolving. The bottom brace strap and medial side metal hinge bottom contacted the tongue & inside padding of my boot (Dalbello Diablos) causing the brace to shift slightly upward when flexing into deep carving turns. This also came into play when trying to make quick turns navigating bumps and causes the brace side ski to alter my intended turn. The upward movement causes pain and swelling in and around the Patella harvest site due to the patellar strap on the brace. Loosening the Patellar strap just made the brace shift further, however did not irritate the tendon as much. I think this will be a brace for mountain biking, surfing and hiking. Going to find another brace for skiing.
    Pros: -Very stable for hiking and other activities that do not require equipment to come in contact with the brace.
    Cons: - Did not work as hoped for skiing. This may just be due to the length of my leg? - Firm tightening caused the strap to slip and fold over inside the metal clasps (buckle?) that the strap runs through which then turns turn the buckle sideways. It then sticks out and creates a narrow pressure point in that spot. - the neoprene webbing seems to have stretched out and does not provide the same compression (without the straps tightened) it did when new. When the straps are tightened the webbing now bunches at the thigh strap.

    Great brace - working very well

    Reviewed by:

    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.
