The Petite knee walker is ideal for adults and some children shorter than 5'2" that desire to reclaim their lifestyle while recovering from a foot and/or ankle injury. The knee pad extends down to a height of 14", which is lower than all of our other units. A bonus is a tight turning radius and a small frame makes it easier to maneuver around. The wheels are the same size as common knee walker units at 8". These features allow for the safe mobility for those customers with a shorter leg to floor measurement!
