If you have knee osteoarthritis, where should management begin? Elizabeth Tracey reports

Let’s say you’ve been diagnosed with osteoarthritis of the knee. Stefan Coombs, an orthopedic surgeon at Johns Hopkins, says management should always begin with conservative measures first.

Coombs: It should take the course of lifestyle changes such as weight loss, activity modification and walking aids, then there's a step up to oral and topical NSAIDs, then there's a step up to injections and nerve ablation procedures and then finally you go to surgery.   :18

Coombs says weight loss is pivotal for many.

 Coombs: Just 10% weight loss of your body weight can actually cut your arthritis pain by 30 to 50%. It may also slow down the progression of the disease or in some cases stop the progression of the disease.    :13
