If you've broken a foot or had ankle surgery and been told to keep weight off it, you've got three main options: crutches, a knee scooter, or a hands-free knee crutch like the iWALK. For most people the knee scooter is the easiest to live with. Here's why, and when it isn't.
Your surgeon or physiotherapist decides how much weight the foot can take and for how long. This guide is about the equipment, not that medical decision.
A quick note on names: knee scooter, knee walker and knee buggy all mean the same thing: a padded platform for your shin on four wheels, with handlebars and a brake.
The quick comparison
| Factor | Knee scooter | Crutches |
|---|---|---|
| How it works | Rest your shin, roll along | Hop on your good leg |
| Carrying things | Yes, in the basket | Hard, both hands are busy |
| Tiring? | Much less | Very |
| Stability | High (4 wheels) | Lower |
| Stairs | No | Yes (with practice) |
| Price | From $252 | We don't sell crutches |
Why most people prefer a knee scooter
- You roll instead of hop. Far less exhausting over weeks.
- You can carry things. The basket takes the coffee and the phone. On crutches, both hands are busy.
- It's more stable. Four wheels and a brake beat balancing on two sticks.
- Less pain elsewhere. Crutches cause sore hands, wrists, and underarms.
When crutches are still the better call
- You have lots of stairs and no other route
- Your space is very tight and a scooter can't turn
- You only need support for a few days, over very short distances
Knee scooter vs hands-free knee crutch (iWALK)
A hands-free knee crutch straps to your bent leg, so you walk on it with both hands completely free. Its maker says it can also be used on stairs, which a knee scooter can't do. That's the big advantage. The catch is that it asks a lot more of your body.
We don't sell the iWALK, so we can't speak from our own experience with it. Here is what its maker, iWALKFree, says you need before you can use one:
- Your injury is to one leg, below the knee, and your other leg is fully functional
- You can bend the injured leg 90 degrees at the knee
- Before the injury, you could walk up and down stairs at a normal pace without a handrail, and you can balance on your uninjured foot
- You weigh up to 275 lb and are roughly 5'2" to 6'2" (with a leg-length check outside that range)
iWALKFree has an online assessment worth doing before you buy. If you don't meet those requirements, or balance is a worry, a knee scooter is the safer and easier choice.
Knee scooter vs wheelchair
A knee scooter needs one fully working leg to push with, and a shin you can rest on the pad with the knee bent. A wheelchair or transport chair is the better option when:
- Both legs are injured, or the injured leg can't bend at the knee
- Balance or strength makes standing on one leg unsafe
- You need to cover long distances, like a day at a hospital or an airport
Indoors only, or outdoors too?
This is the choice people get wrong. The standard knee walker has 8" wheels built for smooth indoor floors. If you'll be on sidewalks, driveways or grass, the all-terrain model has air-filled tires and is worth the difference. Small wheels and a cracked sidewalk are a bad combination when you're already on one leg.
| Model | Best for | Weight |
|---|---|---|
| Standard adult, $270 | Indoors, smooth floors | About 23 lb |
| All-terrain adult, $470 | Sidewalks, driveways, grass | About 26 lb |
| Junior, $252 | Children and petite adults, indoors | About 22 lb |
| Junior all-terrain, $418 | Children and petite adults, outdoors | About 26.5 lb |
Weights are Medline's figures. All four have an adjustable knee pad and handlebar and a hand brake. The adult models fold for the car.
Quick answers
Is a knee scooter better than crutches?
For most foot and ankle injuries, yes: it's less tiring, more stable, and easier on your hands and underarms. Crutches still win on stairs.
Can you use a knee scooter on stairs?
No. If your home has stairs you can't avoid, plan for crutches or a hands-free knee crutch on the stairs, or set up to live on one floor.
Will it fit in my car?
The adult models fold for the car. Call us with your car model if space is tight.
