Evolutionary study links subtle modifications in the morphology of the bipedal knee to osteoarthriti

The human knee is a triumph of design. The joint, which evolved fairly rapidly from our common ancestor with the chimpanzee to accommodate our bipedalism, likely contributed to our success as a species. However, as modern medicine extends the human lifespan, our species have learned pain in the form of osteoarthritis that can accompany the locomotion of this biomechanical masterpiece.
