Product Questions

Is this model also made of Aircraft aluminum?
Question by: john on Jul 5, 2010, 8:03 PM
Yes, but it also has a Kraton coating to protect from chips and damage.
Answer by: Admin on Jul 5, 2010, 8:03 PM
Is the CI version for the MCL? What is the difference between the Legend SE-4 and the Legend?
Question by: Brandon on Nov 5, 2010, 1:03 PM
The CI version will address both ACL and PCL. The Legend SE-4 is the same as the Legend, but with an extra set of pads and liners.
Answer by: Admin on Nov 5, 2010, 1:03 PM
My measurements are K: 17 C:15.5 T: 21.5. What size should I get. Thank you.
Question by: Herbert on Feb 22, 2016, 9:05 AM
You will need to order the large size
Answer by: Admin on Feb 22, 2016, 9:05 AM
I work in manual labor all day for 10-14hrs a day. I have a stage 3 MCL and a stage 2 PCL tear, I'm trying to prolong surgery for as long as possible due to the extensive recovery time and rehab time. Will this brace give me back the mobility to where I could move freely again without the fear of my knee buckling?
Question by: Justin on Apr 25, 2016, 6:31 PM
Yes The SE-4 will provide multi-directional support to the knee but still allow your knoee free movement to do the activites that you need to do
Answer by: Admin on Apr 25, 2016, 6:31 PM
I have an ACL complete tear and meniscus.....my knee is been trying to get out of place several times. Would it matter if I get the brace for ACL or CI?
Question by: Mike on Mar 20, 2016, 4:24 PM
You will want to go tith the CI strapping, as this will be the most supportive to you
