What is a Knee Scooter? The Best Crutch Alternative

  • by

A knee scooter, also known as a knee walker or knee roller, is a type of mobility aid used to help people who are unable to put weight on their foot or ankle due to an injury or surgery. The device is an alternative to traditional crutches, providing the user with a comfortable and stable platform to rest their injured leg on while moving around. A knee scooter’s purpose is to allow people to maintain their mobility and independence while recovering from an injury or surgery.

Knee scooters are commonly used to recover from:

  • Foot or ankle injuries,
  • Achilles tendon injuries, and
  • Lower leg injuries such as fractures.
  • They are also commonly used following foot or ankle surgery.

Knee scooters are also known as knee walkers. They are more comfortable and convenient alternative to crutches for many people because they allow users to use both hands and reduce stress on the arms and armpits. It’s also a non-weight bearing solution for lower leg pain as it provides a padded platform to rest the injured leg. In this article, we will take a closer look at knee scooters and discuss the various types available, their benefits, how to use and operate them safely, and some tips for choosing the best one for you.

How Does a Knee Walker Work?

A knee scooter is intended to provide support for your injured leg while moving around. It typically consists of a knee pad, a set of handlebars for steering and balance, and four wheels for mobility. The knee pad can be adjusted to fit users of various heights, and the handlebars are foldable for storage or transportation.

To use a knee scooter, the user must first ensure that the knee pad is adjusted to the correct height for their injury and that the handlebars are at a comfortable level. They will then place their injured leg on the pad and push themselves forward while holding onto the handlebars for support and balance.

When using a knee scooter, it is critical to follow all safety precautions. This includes:

  • Making sure the knee scooter is adjusted to the proper height,
  • Not exceeding the weight capacity,
  • Ensuring the wheels are properly inflated and in good working order, and
  • Exercising caution when traversing uneven terrain.

Furthermore, individuals who have been prescribed a knee scooter by a doctor should follow the usage instructions provided by the health care provider and stick to the timeline they have provided. It is also important to be aware of the symptoms of knee scooter overuse, such as pain, swelling, or redness on the leg.

It is important to note that knee scooters are not for everyone, and that traditional crutches, wheelchairs, or walkers may be more appropriate in some cases. Before using a knee scooter, always consult with a healthcare professional to ensure it’s the right choice for you and to receive instruction on proper usage.

What Are the Benefits of Using a Knee Scooter?

Using a knee scooter instead of traditional crutches has several advantages, including:

A. Less weight on the injured leg

One of the most significant advantages is that knee walkers are designed to reduce the amount of weight bearing on the injured foot. This can help to relieve pain and discomfort while also promoting faster healing. Furthermore, knee scooters often provide more comfortable knee cushioning than crutches, which can help to reduce pressure on the injury and the risk of further injury.

B. Increased mobility and independence

Knee scooters allow people to remain mobile and independent while recovering from an injury or surgery. This is especially useful for people who have injuries or conditions that make using crutches or walkers difficult. Individuals can move around more easily with a knee scooter, allowing them to continue participating in their daily activities and avoid isolation.

C. Faster recovery time

Knee scooters can help promote faster healing and recovery time by reducing the amount of weight bearing on the injured leg. Additionally, using a knee scooter can help to prevent muscle weakness caused by prolonged crutch use. Knee scooters can aid in the recovery of an injured leg by keeping it active and engaged.

It is important to note that knee scooters are not for everyone and should only be used under the supervision and care of a health care provider and/or physical therapist.

How to Choose the Right Knee Scooter

When selecting a knee scooter, it is critical to consider the individual’s specific needs as well as the environment in which the scooter will be used. Here are a few things to remember:

Knee scooter types

Knee scooters come in a variety of styles, including traditional models and all-terrain models. Traditional models have smaller wheels and are intended for indoor use, whereas all-terrain models have larger wheels and can be used both inside and outside.

Important considerations

  • Position of the injury: Knee scooters are not suitable if you have a knee injury or injuries above the knee. Only consider a knee scooter if your injury is below the knee such as a sprained ankle.
  • Weight capacity: Select a knee scooter that can support the user’s weight.
  • Adjustability: A knee scooter with adjustable handlebars and a knee pad can provide the user with a more comfortable fit.
  • Dimensions and portability: Consider the size of the knee scooter as well as its portability. Some models can be folded to make storage or travel easier. Be aware that knee scooters cannot navigate stairs. If this is an important factor for your mobility, consider some alternative assistive walking aids.


  • For indoor use: A traditional knee scooter with small wheels is ideal for indoor use, especially for those with limited mobility or who need to navigate tight spaces.
  • Outdoor use: An all-terrain knee scooter with larger wheels is a better choice for those who will be using the scooter outside because it can better navigate uneven surfaces and gravel.

It is critical to consult with a healthcare professional or physical therapist to determine the best type of knee scooter for your specific needs. They can also advise you on proper fitting and usage. It’s also a good idea to try out the knee scooter before buying it to make sure it’s comfortable and simple to use.

Is a Knee Scooter Better than Crutches?

Crutches and a knee scooter are both commonly used to assist people recovering from an injury or foot surgery, ankle, or foot. Both have advantages and disadvantages, and which is better for you may be determined by your specific needs and circumstances.

A knee scooter may be a better option for someone recovering from a lower leg injury or surgery who can bear weight on their good leg and has good balance. Crutches may be a better option for someone recovering from an above-knee injury or surgery, or for someone who lacks good balance or upper body strength.

What are the advantages of Knee Scooters?

  • They are usually more comfortable to use than crutches because you can rest your injured leg on a padded platform and propel yourself forward with your good leg. This can aid in the relief of pain and fatigue in the injured leg.
  • Knee scooters are more stable in general than crutches, which can be less secure and more prone to slipping.
  • They are more maneuverable than crutches, especially on uneven surfaces or indoors.
  • They can be a more efficient and faster mode of transportation than crutches.

What are the advantages of Crutches?

  • In general, they are less expensive than knee scooters.
  • They are more portable than knee scooters and are easily folded and stored.
  • They give you more freedom of movement because you can use your hands and arms to hold onto things.
  • They don’t need much room to move around.

Finally, based on your injury, recovery progress, and specific needs, your doctor is the best person to advise you on which option is best for you.


For people recovering from an injury or surgery, knee scooters are an excellent crutch alternative and they are comfortable to use. They provide a stable platform for the injured leg and allow for hands-free movement, which reduces strain on the arms and promotes faster recovery.

There are various types of knee scooters available, and it is critical to select the right one for your needs. Weight capacity, adjustability, size and portability are all important factors to consider when purchasing a knee scooter.

When compared to crutches, the advantages of using a knee scooter include reduced weight-bearing on the injured leg, increased mobility and independence, faster recovery time, and cost-effectiveness. However, keep in mind that knee scooters are not for everyone, and you should consult with a healthcare professional to ensure that it is the right choice for you.

Finally, it is critical to use a knee scooter correctly and to follow the instructions and guidance provided by your healthcare professional to ensure safe use and avoid any additional complications.
