Some 30 years ago, the rolling knee walker was not yet in existence. The rolling knee walker is not a new concept though. It is a descendant of a long line of walking aids.
In an article published in the British Medical Journal, researchers Webling and Fahrer found that the precedent of the rolling knee walker called “bent knee prostheses” have been in existence, as depicted on a vase, in the 4th century BC. The researchers also found that paintings from the 15th and 16th centuries depicted these bent knee prostheses.
These bent knee prostheses remained underdeveloped until Michael Reid made the first K9 orthopedic scooter after he suffered a very bad foot injury. The K9 orthopedic scooter has four wheels, a pad to elevate the injured leg and a handle.
The modern rolling knee walker like the steerable knee walker is a descendant of the bent knee prostheses and K9 orthopedic scooter. The steerable rolling knee walker has four wheels, a pad to elevate the injured leg, a handle and a hand brake. This walking aid is steered using the knee.
Who Can Use the Rolling Knee Walker
The rolling knee walker is frequently recommended by orthopedic surgeons to people with the following conditions:
-Lower leg injuries/disabilities
-Lower leg amputations
-Ruptured Achilles tendons
-Diabetics’ trophic plantar ulcers
People with the above-mentioned conditions are required to remain non-weightbearing on the injured leg part.
Benefits of Using Rolling Knee Walker
A study by Paul Roberts and Susan Carnes from the Royal Orthopedic Hospital in Birmingham found that the rolling knee walker offers the following benefits to users:
1. It requires 25% less energy than crutches.
2. The injured leg is elevated.
3. The body weight of the user is distributed through both legs.
4. The muscles near the injured leg are regularly used.
5. The muscles bulk near the injured leg is preserved.
6. The bone strength is preserved.
7. When not in motion, the rolling knee walker has been found to free both hands. When moving, one hand is free to be used for other purpose.
