FROM OUR EXPERTS
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. (I'll wait while you grab your high school physics book). There are plenty of folks who do not have patellae, but because this causes the quad muscle to work inefficiently, few of these folks can run or climb stairs well. The design issue with the patella is that it articulates, or rubs up against, the end of the femur bone (thus the "patellofemoral" joint). For those of us who have pa...
Why is it that most running injuries occur at the knee or in the lower leg? Is there some common factor that might be involved? The authors of this study set out to look for some answers to these questions. They didn't do a study themselves of runners. Instead they turned to the literature and did a search of all the published articles on running injuries. Research studies like this are possible now that everything is contained within an electronic database. Four of the most well-respected electronic databases (e.g., MEDLINE, EMBASE, PsychoInfo, CINAHL) were accessed for information on risk factors for overuse running injuries. By doing a search with words like running , injury , mechanics . and knee , they were able to find 283 articles on running injuries published between 1980 and 2008. They narrowed the search down by looking for running injuries in long-distance runners who ran at least 20 kilometers (12 miles) each week. The athletes were recreational or competitive runners (not elit...
Definition The tibia is the larger of two long bones in the lower leg (between the knee and ankle). It is sometimes called the shin bone. See also: Long bones Information
