Early
Steps Can Protect Your Knees, Prevent Later Problems
(HealthDay News) -- Protecting your knees when
you're younger may help prevent serious problems such as arthritis and the need
for knee replacement when you're older, an expert advises.
Research indicates that nearly half of adults
develop arthritis in at least one knee by age 85, and the risk is even greater
for obese people. Extra pounds increase the strain on knee joints, noted Dr.
William J. Bryan, an orthopedic surgeon at the Methodist Center for Sports
Medicine in Houston.
"Every time you take a step you apply three
times your body weight to the knee. When you run it's five times, when you jump
it's seven times. If you are experiencing frequent knee pain, lifestyle changes
might be in order," Bryan said in a news release from the Methodist Center
for Sports Medicine.
Weight loss is 70 percent diet and 30 percent
exercise, he explained. "If you think you can eat the same and exercise
the pounds away, you are mistaken. You have to change your attitude about the
refrigerator for weight loss to happen," he said.
In terms of exercise, low-impact activities such as
swimming and cycling are better for your knees than high-impact workouts such
as running or aerobics. Having good core strength (abs, back and pelvis) also
helps protect your knees, Bryan noted.
"If you have a strong core, you can better
position your foot or knee on the ground to prevent damage. This is true
whether you are exercising or performing mundane tasks such as getting out of
the car and walking down the stairs," Bryan said in the news release.
Orthotics may also help protect your knees. Your
knees can be subjected to abnormal stress if your shoes don't give you a stable
base as you walk. Many patients experience dramatic reductions in knee pain
after getting orthotics or shoes specifically made to fit their feet, according
to Bryan.
"If you have knee pain that has lasted more
than two weeks, you need to see a doctor because there might be something
mechanically wrong with the knee," he said. "Making a few lifestyle
changes might give you a better chance at staving off arthritis and/or eventual
knee replacement," he added.
