I'm selling two GII Trainer braces, one for the left and one for the right knee. Size is small.
The Trainer is suitable for general ligament instability, management of MCL tears, unloading the medial side of the knee and helping keep the kneecap in the right place. I used them primarily for management of chronic patellofemoral syndrome in both knees. They were extremely helpful for allowing me to continue high level sports, including skiing, while the PFS was really bad. Thankfully with a good physiotherapist it improved to a point where I haven't needed to unload the knees in a long time, so I no longer use the braces.
Here's a picture and some more information: http://www.diamondathletic.com/product;cat,4;item,1024;Knee-Braces-GII-Trainer
The left brace was used heavily; it's in solid condition but looks a bit more worn. The right one I didn't use nearly as much, so it's in very good condition.
They generally retail for around $400. I'm looking for $100 for the left brace and $150 for the right brace. Drop me a message or leave a post on this thread if you're interested.
