6 Ways to Ruin Your Knees

 Whether you're a seasoned athlete, a weekend warrior, or totally laid-back when it comes to exercise, knowing how to protect your knees from damage can mean the difference between a fulfilling lifestyle and longterm, strained mobility. Cruising on the track in the heat of a roller derby match, 27-year-old Rachel Piplica was not at all prepared for the realization that her knee could sideline her from competitive skating for months, possibly years.

Arthritis Myth or Fact: Arthritis is just part of aging.

Myth. The idea that getting older means living with joint pain is probably one of the most persistent arthritis myths out there.

Yet, arthritis isn't a natural part of aging, and older people aren't the only ones who get arthritis. As a matter of fact, more than half of the 50 million people living with arthritis in the United States are under age 65, says Patience H. White, MD, MA, vice president for public health policy and advocacy for the Arthritis Foundation. Even children get arthritis.

It is true that your chances of getting osteoarthritis -- the most common form of arthritis, affecting 27 million Americans -- increase with age. One reason is simply that older joints have had more wear and tear. Although there's nothing we can do about growing older, there is a lot we can do about the other OA risk factors.

Arthritis Myth or Fact: You can't prevent osteoarthritis.

Myth. For some, arthritis is in the genes; if one of your parents has osteoarthritis -- particularly in the hands -- chances are good that you will, too.

For the rest of us, the most common causes of OA can point us toward a path of prevention:

  • Obesity plays a huge role in raising your risks of developing osteoarthritis, especially for osteoarthritis of the knee. That's because the heavier you are, the more stress you put on your joints.  For each 1-pound increase in weight, the force across the knee joint increases by 2 -3 pounds. To lower your chances of getting OA, lose weight if you're overweight, and then maintain a healthy weight when you get there.
  • Overuse or injury also raises your risk of developing OA. According to the Arthritis Foundation, athletes and people whose jobs require repetitive motion have a higher risk of developing osteoarthritis because of joint stress and injury. High-intensity sports such as running, which directly impact joints, seem to increase the risk of osteoarthritis. The key to prevention? Avoid injuries, and modify movements so your joints are stressed less. For high-impact sports, gradually increase your training schedule and avoid high-impact activities if your joints are injured.
  • Muscle weakness is another risk factor for OA. In particular, some studies show that weakness of the muscles surrounding the knee (quadriceps) can raise your risks of injury and knee osteoarthritis.
  • Other types of arthritis and conditions, like rheumatoid arthritis, can also increase your chances of developing OA.
