Product Questions

Can the undersleve be worn with the OAdjuster Knee Brace?

Also what is the difference between the Replacement Kit-Lateral and the Replacement Kit- Medial for the OAdjuster? They appear to be identical.
Question by: Tom Reid on Apr 4, 2010, 12:21 PM
The DonJoy Knee Brace Undersleeve - Supplex/Lycra can be worn under the DonJoy OAdjuster Osteoarthritis Knee Brace. Just be sure to match the sizing of the brace with the sizing of the sleeve (Large brace - Large sleeve, etc)

does the knee brace undersleeve have a seam
Question by: Michael Hewett on Jun 4, 2010, 4:34 PM
There is a thin seam that runs the length of the sleeve on the back of the leg and very comfortable against the skin and under a knee brace.

Does the cover give any extra protection or stability to the knee?
Question by: Eric Denis on Jun 19, 2010, 11:26 AM
This knee brace undersleeve is designed to protect the skin by adding a layer of comfortable material between your skin and the knee brace. It does not necessarily add any support or stability to the knee.

Will the knee brace undersleeve help with sweating and such from wearing the <a href='/knee-braces'>knee brace</a> outside on hot days?
Question by: Mike on Jul 6, 2010, 2:55 PM
It will help in that it will help absorb the moisture. It won't keep the knee cooler, but it should make wearing the knee brace more comfortable.
