This document is intended for people who begin to feel knee pain due to aging or other reasons. (For moderate or severe knee pain, conservative therapy or surgery may be indicated by the attending physician. If there are "things that you want to try" in the information in this document, consult with your attending physician and follow the instructions in the Getting Started section.) For people with mild knee osteoarthritis or those who are not, we will introduce training to prevent deterioration, such as teaching people how to self-care their knees that have been damaged by aging or living, reviewing their lifestyle, and improvement of muscle strength to support their knees.
