Human beings are well designed for many things. We have large brains for poetry and quantum mechanics; we are good long distance runners, and of course have these awesome opposable thumbs. Unfortunately, some parts are not designed very well for our 21st century lifestyles. The low back , or lumbar spine, is first on my list for sending back (or forward?) to the engineers. A close second though might be the " knee cap " or patellofemoral joint.
The "knee cap" or patella is an ovoid shaped bone whose main purpose is to act as a fulcrum that big muscle on the front of your thigh, the quadriceps.

Mirco-injury to ligaments and cartilage leave a joint vulnerable to the effects of overuse, stress, and aging . Thus, these joints become arthritically inflamed and painful later. The price of pain might be in years to come, but it will come. Take a look at the common injuries associated with some popular summertime activities.
