Knee and leg pain.

A knee rarely fails on its own. It sits between a hip and an ankle and absorbs whatever those two are not doing properly. Which is why treating the knee alone, over and over, works for some people and does nothing for others.

The exam looks at how the whole leg loads. A hip that has lost rotation, an ankle that stopped dorsiflexing after an old sprain, a foot that collapses on one side more than the other. Any of those puts a knee under stress it was not built for, and no amount of treatment aimed at the joint itself changes the reason it keeps getting angry.

Wear on a scan is not the whole story

Plenty of people arrive with imaging showing arthritic change and advice to manage it until a replacement makes sense. The wear is real. It also does not account for all of what you feel. Muscles compensating around a stiff joint and a nervous system that has been guarding the area for years make up a share of the pain, and those parts respond even when the joint surface does not change.

Who this tends to be

Retirees carrying twenty years of load-bearing. Runners and walkers who picked up something that will not settle. People who took a fall, kept going, and never quite got back to normal on that side. And anyone who has started planning their day around how many stairs are in it.
