McDavid Knee Anatomy

The Anatomy of The Knee

The knee is a complex joint that is relatively unstable during any high-impact activity. This instability is a cause of the most frequent serious sports injuries. Our braces and supports offer varying degrees of support, protection and pain relief by compressing the soft tissue and keeping the knee warm.

it works

I have an older version of this brace. I needed another one for my other knee. Both work stabilizing my knees as I work out at the gym. A good product.

I love my new brace!

This brace fits well, offers excellent support, is easily adjustable & is quite comfortable. I will definitely shop here for braces in the future!

Good Knee Brace

Good knee brace. Comfortable all around even behind my knee. It feels great wearing it.
