At the Movement Assessment Technologies we are big believers that the knee joint is actually pretty dumb. The reason for this is that it's actually a simple joint often caught between what happens above (hip, spine) and below (foot, ankle).
So while pain can present around the knee often the fault of the problem can be found elsewhere meaning that the knee has to do more or perform a role that it's not designed to do, resulting in acute or repetitive pain.
Remember when assessing your knee pain clients or patients to take into account what's happening above and below rather than just treating the symptoms of the knee area.
