Sometimes knee joint replacements fail. There can be loosening of the implant, fractures of the bone, or lingering knee pain. The implant may have to be removed and replaced with another one. Each knee joint replacement has three main parts. There's an upper piece called the femoral component. The lower half is called the tibial component. The third part is the kneecap or patellar component. What if the implant has failed and there's nothing wrong with the patellar component? Does the patellar part have to be removed and replaced, too? Doctors at four centers in Philadelphia, Baltimore, and Boston studied this question. No one really knows how long these components last, but the old saying, "If it isn't broke, don't fix it," might be good advice in these cases. The records of all patients in these centers who had a total knee revision were reviewed. Only patients whose patellar part was left untouched during the revision surgery were included. The researchers found that if the kneecap w...
First, understand that there is no
"magic supplement" that will cure osteoarthritis. In this post, we'll talk about the real difference
between supplements and arthritis medication, how to select a supplement to buy
and about a few common osteoarthritis supplements, including glucosamine and

associated with osteoarthritis is stretching and strengthening the surrounding
muscles in the right way.

medicinal purposes since the beginning of civilization. Of every 10,000 compounds sampled, perhaps
one will make it to market. And that
process of bringing a new drug to market takes 10 to15 years and can cost more
than $1 billion dollars. That's a lot of
money! Considering the abundance of
potential natural therapeutic agents out there in the world, it shouldn't be
surprising that some of them have not yet been ...
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
