FROM OUR EXPERTS
In this year of Hillary and Sarah, it is interesting that gender issues in medicine are becoming important... and profitable.
In 2006, Zimmer, Inc. received clearance from the United States Food and Drug Administration to market an artificial knee that is gender-specific. This is based on studies that have focused on the anatomical differences between men and women. Specifically, men have been found to have an increase in the contact area where the knee cap meets the rest of the knee joint compared to women. And women appear to have a more narrow space when one looks at the inner and outer aspect of the knee.
Osteoarthritis of the knee is a major cause of chronic pain and disability, and the concern up to this point is that perhaps the orthopedic profession and its suppliers of artificial knees are doing a disservice to some patients by not taking into account the differences between a male knee and a female knee. All of us know patients who have chronic pain even af...
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...
One of the first questions I sometimes hear from people who have knee pain is: Doc, do you think it is arthritis? The answer is, invariably, please tell me more about your pain. There are many causes of knee pain and arriving at an accurate diagnosis begins with a full, comprehensive medical history and physical examination. Osteoarthritis is one of the more common causes of knee pain in people over the age of 55. However, there are many other potential causes in this population of people as well. For example, knee pain can be due to:
Ø A meniscus tear
Ø A ligament tear, sprain, or strain
Ø Malalignment of the patella (knee cap) leading to pain beneath the patella
