Why does the GenuTrain P3 come in right or left versions?
A. GenuTrain P3 is anatomically knit to fit the right or left leg for comfortable, effective therapy. It also has a silicone insert with a tracking guide to prevent the patella from shifting out of place. The guide is always on the lateral (outside) of the insert, because the patella shifts in this direction. Therefore, there is a left and right version to ensure that the tracking guide is on the correct side.
