The Importance of Ankle Mobility

If someone has a history of slipped cap femoral epiphesis or leg cap perthies, if they have an advanced arthritic process at the hip, all these things can refer to the knee and the medial knee. You would want to look at a fulcrum test just to make sure that we're dealing with a knee problem or a hip problem versus something else. And you would also want to looks at ankle mobility. Some people have stiff ankles and it's not necessarily a problem but Peter Malayaris' work with volleyball players found that some had less ankle dorsiflexion.
