The Cho Pat dual action knee strap provides an extra dimension of relief to stabilize and tighten up the kneecap mechanism. The strap applies constant pressure, above and below the knee cap, to allow for relief from painful and weakend 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 results. Measure around leg at mid kneecap.
