Product Questions

OA pain on outside of my left knee. Thigh 24", Knee 19 1/2", Calf 19. Medial or lateral and what size would you suggest for the Reaction Web?
Question by: Kenny on Jul 21, 2016, 6:57 AM
You would be a size XL, and select the option Medial Right/Lateral Left.
Answer by: Admin on Jul 21, 2016, 6:57 AM
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?
Question by: Tia on Nov 4, 2014, 2:23 PM

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.

You will want the right lateral/left medial brace. The brace will have the hinge and upright on the inside of your knee and will push towards the outside to unload that compartment. This unloading will hopefully decrease some of the pain you are feeling on the outside of your kne and the webing will help decrease pain under the kneecap.

I have OA in my left knee all of my pain is on the outside and front of my knee is the OA reaction brace the right choice for me I'm an avid golfer and which option should medial/lateral option should I choose
Question by: Ryan on Apr 21, 2016, 9:46 PM
Yes the OA Reaction would be an approriate brace for you to use. You would want to have the hinge side go on the inside of your knee to unload the outside. You would order the right medial/left latera brace
Answer by: Admin on Apr 21, 2016, 9:46 PM
Am looking at a brace for my right knee - pain is allover the knee, but maybe worst on the inside but with swelling on the right side (!) Which medial/lateral option would I need?
Question by: Shirley K on Mar 17, 2016, 9:13 AM
You want to order the right medial/left latera brace and when you get the brace the hinge will go on the outside of your knee

Note: Knee measurement is the most important, if you measure between sizes we recommend going up one size for optimum comfort and fit
