The most common cause of knee
damage requiring knee replacement is osteoarthritis, which is a
degenerative disease of the bones of the knee which cause the surfaces
of the knee joint to become irregular and rough, preventing smooth
painless motion of the knee joint.
Knee joint replacement may be recommended for:
osteoarthritis or arthritis, which causes knee pain that has failed to
respond to conservative therapy (NSAID medication for 6 months or more)[emphasis mine]
decreased knee function caused by arthritis
inability to work because of knee pain
inability to sleep through the night because of knee pain
inability to walk more than 3 blocks because of knee pain
loose knee prosthesis
some knee fractures
So "conservative therapy" is pain management through NSAIDs for 6 months? How is pain management supposed to make the problem better?
What about taking some calcium and magnesium? What about trying glucosamine sulfate? Fish oil? Systemic enzymes? All of these have plenty of clinical studies.
Healthline.com won a Webby this year for being the best health website
on the net. Not surprisingly, it has history and ties to pharma giant Merck. I've looked at Helathline.com several times in the last 6 months. As far as I can tell, Healthline is garbage.
Of course I'm biased, but if you want to research natural and alternative cures, go to the database at JigsawHealth.com.
