The results of any one medical study can offer good information. But comparing the results of many studies is even more helpful. This is called meta-analysis . In this meta-analysis doctors compared the results of total knee replacements (TKRs) with and without patellar resurfacing. This means the bony kneecap is removed. It's replaced with a metal or plastic-backed implant. The authors asked these questions: Are there fewer cases of reoperation when the patella is resurfaced? How often does knee pain occur after each type of operation? What kind of knee function is possible? Ten studies including 1,223 knees had data that could answer these questions. Researchers used number of reoperations, knee pain, and function to measure results. They found there were fewer reoperations and less knee pain for patients with resurfaced patellae. Knee function seemed to be about the same in both groups.
Other studies show a higher number of reoperations over time for patients with resurfaced patellae. ...
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
chondroitin . Also, note that the most effective, lasting treatment for the pain
associated with osteoarthritis is stretching and strengthening the surrounding
muscles in the right way.
What Are Supplements?
People have been using plants for
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 ...
