What hypermobile knees say
Thousands of people with hypermobile, unstable knees wear Theravyn every day — because it's the first brace they didn't take off.
The first brace I actually keep on
Every compression brace I tried made my knee hurt more, so they all ended up in a drawer. With Theravyn I set it loose in the morning and turn the dial up when my knee gets tired. I wore it through a full 9-hour shift on my feet and forgot it was there.

Finally stable on stairs
My knees hyperextend and lock when I stand still, so stairs and standing in line were the worst. Since I started wearing Theravyn my knee feels held in place and I'm not doing that constant mini-squat to keep it from locking. It doesn't slide down either — that was my biggest worry.

Wear it under jeans, nobody notices
I'm still doing my PT, but on bad days I need something now. This is slim enough to wear under work trousers and I can adjust it in two seconds when it feels too tight. I ordered a second one for the other knee a week later.
