Choosing an assistive device for knee osteoarthritis hinges on assessing the patient’s balance, strength, and weight‑bearing tolerance and then trying devices to see which gives the necessary support while preserving independence. Start with a functional evaluation: determine how well the patient can maintain stability, bear weight through the affected knee, and perform tasks safely. Have the patient trial both a cane and a rolling walker, observing how each affects gait, stability, energy cost, and the ability to perform daily activities. The device that provides the needed support without overly limiting movement or independence is the best fit, and it should be adjustable and easy for the patient to use at home.

To monitor progress, use objective measures such as gait speed (how fast they walk over a standard distance), the total distance walked in a set time or during a functional test, chair-rise ability (time or reps to rise from a chair), and pain levels during activity. Improvements in speed and distance, easier chair rises, and reduced pain indicate positive functional progression with the chosen device.
