Not only does PA Medical Supply offer walkers and rollators, they also offer knee walkers. Knee walkers are an alternative for crutches, wheelchairs and regular walkers. These knee walkers are most often used by people who cannot bear weight on a particular leg due to a temporary injury or permanent disability. Much like a rollator, the knee walker enables mobilization with wheel bases for easy maneuvering. One leg rests on the support platform, while the other leg pushes to propel the user in their desired direction.
