Provides an extra dimension of relief for painful and weakened knees. The strap applies pressure upon the patella tendon below the kneecap to stabilise and tighten up the kneecap mechanism, which improves patella tracking and elevation and reduces patella subluxation. It adds further strengthening to the kneecap mechanism by applying pressure on the tendon above the kneecap. This tends to reduce the forces of the quadriceps on the patella tendon and erosion of the undersurface of the kneecap due to a possible misalignment of the quadriceps (Q angle). Constant dynamic forces are applied to the surrounding areas of the knee, reducing the likelihood of overuse syndromes. At the same time, the strap allows for full mobility while providing maximum benefits. For size, measure circumference above kneecap.
