Knee Replacement

Knee Replacement

There is an increasing trend toward knee replacement (total knee arthroplasty) in treating knee osteoarthritis.  A teaching hospital in Hong Kong looked at 750 patients who had their knees replaced from January of 2000 to December of 2009.

The number of total knee replacements increased from 91 in 200 to 181 in 2009.  There were 588 females who had their knees replaced compared to 162 males with 589 left knees being replaced and 568 right knees.  The men age of the patients having their knees replaced did not change significantly but the number of patients over 80 years of age increased from 4.8% to 13.8%.

Vitamin D

Vitamin D

Research presented at the American College of Rheumatology’s Annual Scientific Meeting in Atlanta shows that increasing vitamin D intake will most likely not help slow down your osteoarthritis of the knee.

The study examined looked at two groups of patients, one was given vitamin D, and the other was given a placebo.  X Rays and functional testing were performed on each patient at the beginning and end of the study.

Lead Investigator at Tufts New England Medical Center, Timothy McAlindon, said, “This study tested whether vitamin D supplementation , given over a two-year period, could influence the rate of progression of joint damage in people with knee osteoarthritis.”
