The strap applies constant pressure, above and below the knee cap, to allow for relief from painful and weakened knees. While still allowing full mobility, this pressure helps tighten and strengthen the kneecap mechanism, allowing for improved patellar tracking and elevation, reduced patellar sublaxation and reduced quadricep misalignment under the surface of the kneecap. The Cho Pat dual action knee strap is available in multiple sizes for a more specific fit and more effective result. Measure around leg at mid kneecap.</br><br/>http://www.amazon.com/gp/product/B000QRG970
