Walking with a cane is a recommended mobility aid for the elderly or people with knee osteoarthritis. Using a cane properly helps reduce the load on painful joints, reduces the risk of falls and helps patients move more steadily. When using a cane, we need to ensure that as much of the body weight as possible is carried through the cane. This is very important because it helps protect the knee joint from further damage and inflammation. The question that patients often ask us is: 1) How much body weight should people with knee osteoarthritis support with a cane? 2) How can the cane support the most body weight?
