Even though height ranges are given by the manufacturers, they are subjective since everyones legs and torsos are different proportions. A customer who is 5’2″ but has longer legs may be able to use one knee walker that a customer who is 5’3″ with shorter legs may not. It all depends on measurements. The best way to know for sure if a knee scooter will be the correct size for you is to measure. For an accurate measurement you will need:
A tape measure or yard stick.
A friend or family member to help measure is recommended.
A solid, stable item to hold onto, such as a chair, counter or wall to balance yourself with.
Once you are safely balanced, bend your leg that will be on the knee walker to a 90 degree angle as if it were resting on the knee pad. Make sure you are standing up straight and not leaning. Next, measure the distance from the bottom of your bent knee to the floor (see figure below).
If your measurement is between 17″-20.25″, all of our knee scooter models are options for use. For users that are a little shorter, the Roll-A-Bout model is popular since it goes a full 2 inches lower than the other models. For taller users, where the measurement is 20.25″-23.25″, the Free Spirit or Roll-A-Bout are the models you would want to take a look at.
All of our knee walker models feature adjustable height knee pads and handle bars to ensure the proper alignment. With the knee scooter set up properly, your hips should be even and you should be able to stand comfortably with your uninjured foot flat on the ground. You should be in an upright position as if you were standing normally. The knee scooter handle bar should be set at waist height in a natural position so the arms and hands are comfortable when outstretched. Please see the figure below for proper knee scooter posture.
