For anyone facing a foot or ankle injury, the immediate question is how to stay mobile without putting weight on the injured limb. For decades, crutches were the go-to solution, but in recent years, the knee walker has emerged as a popular and often more comfortable alternative. The choice between these two mobility aids can significantly impact your recovery, daily routine, and overall well-being. This comprehensive guide will break down the pros and cons of both options, helping you make an informed decision for a smoother rehabilitation.
Crutches: The Traditional Choice
Crutches are the most common and recognizable form of non-weight-bearing support. They are lightweight, relatively inexpensive, and easy to store.
How They Work
Crutches consist of two long shafts with a padded top that goes under the armpit and a handgrip for support. They work by transferring your body weight from your legs to your upper body, allowing you to “walk” or hop forward while keeping the injured foot or ankle off the ground. There are two main types:
- Axillary (Underarm) Crutches: The most common type, they are often provided in a hospital or clinic setting.
- Forearm (Lofstrand) Crutches: These have a cuff that goes around the forearm, offering more control and are often preferred for long-term use.
How to Use Crutches Properly
- Proper Fit: The top of the crutch should be about 1 to 1.5 inches below your armpit. Your elbows should be bent at a slight 15 to 30-degree angle when you hold the handgrips. The handgrips, not the armpit pads, should bear your weight.
- Walking: Place both crutches about one foot in front of you, slightly wider than your feet. Lean on the handgrips, swing your body forward, and place your good foot on the ground.
- Stairs: To go up, lead with your strong leg first, then bring the crutches up. To go down, place the crutches on the step below, and then bring your injured leg down first, followed by your strong leg.
Knee Walkers: The Modern Alternative
A knee walker, also known as a knee scooter, is a wheeled mobility aid with a padded platform for the injured leg to rest on. It works much like a regular scooter and is becoming an increasingly popular alternative to crutches.
How They Work
You place the injured leg with the knee bent on the padded platform and push off the ground with your healthy leg. The user steers with a handlebar and controls their speed with handbrakes. This device keeps the injured limb completely elevated and non-weight-bearing, all while providing a stable, rolling base.
How to Use a Knee Walker Properly
- Proper Fit: The height of the handlebars should be at your waist or hip level, and your arms should have a slight bend in them. The knee platform should be adjusted so that your good foot is flat on the floor and your hips are level.
- Steering and Braking: The handlebars function like those on a bicycle. Squeeze the hand brakes to slow down or stop. Make sure you take wide, sweeping turns to prevent the device from tipping over.
- Safety: Always check the brakes and tire pressure before each use. Never use the device on stairs or escalators.

Conclusion: Which is Right for You?
The best choice depends on your personal needs. Choose crutches if you need an affordable, versatile option for short-term use and must navigate stairs frequently. Opt for a knee walker if you have a longer recovery ahead, need your hands free, and prioritize comfort and stability. Always consult with your doctor or physical therapist before making your final decision.
