  • From Jerry at 10/12/14 5:45 PM
    • I don't understand the options. Does the specified option refer to the primary location of the pain? For example, my primary pain is medial left. Is that the option that I should choose?
    • Jerry if you have pain on the inside of the left leg then you are going to choose the left medial.

    • Hello,
      It was stated that this was for early cartledge degeneration of the knee. I have moderate to sever degeneration under the patella, where my knee hurts around my entire knee, will this knee brace help or is there one that would work better.

      Thank You
    • Neoma
      The OA Reaction Web Knee Brace is for those with mild compartmental OA in the knee. If you have OA under the kneecap the Reaction Web Knee Brace would be the correct brace for you. The Reaction's web design is going to absorb force on the fron tof the knee a dispearse the force away from the kneecap to decrease pain.

    • Do major insurance companies cover the OA Reaction Web Knee Brace?
    • Susan
      Insurance companies do usually cover the OA Reaction Web, but you may have to check with your insurance company to be sure

    • I have seen multiple comments about both of your web braces having poor Velcro quality and having to replace it within a few weeks. Have you fixed this problem? Other people have stated that yiu have yo practically cut off circulation to get it tight enough not to slide. Are there braces out there that will stay put and last?
    • Tia
      We have updated the velcro on the Reaction Web knee Brace, with a better velcro hook to address the problems people were having with the earier brace.
  • From Marion Godwin at 11/16/14 12:44 PM
    • Can this brace be adjusted to lock the knee in different positions, i.e. 45 degrees
      90 degrees, etc. ?
    • Marion
      No this brace does not do that, it does not have metal hinges on it. The TROM Advanced is the only brace on this website that will do that.
  • From Dan at 11/17/14 8:32 AM
    • Can an flex spending account be used to purchase the reaction knee brace?
    • Dan
      As long as your insurance alows DME to be purchased with the card it will be fine on our end
