Knee Replacement May Be a Lifesaver for Some


By the time 64-year-old Laura Milson decided to undergo total knee replacement after 12 years of suffering from arthritis, even a short walk to the office printer was a struggle.

After her surgery last August at the Rothman Institute at Thomas Jefferson University in Philadelphia, Ms. Milson spent a week in rehabilitation and says she hasn’t stopped walking since. “My son says to me, ‘You have to slow down,’ and I say, ‘No, I have to catch up!,’ ” she said. “It’s a whole different life.”

For Ms. Milson, who lives in Shrewsbury, Pa., replacing the joint in her right knee came with a surprising bonus: a 20-pound weight loss in two months. “I joked with my doctor, ‘I think you put a diet chip in my knee,’ ” she said. “The weight just sort of came off.”

Now she has joined Weight Watchers to drop a few extra pounds and is training for a three-day breast cancer walk in October.

For years surgeons have boasted of the pain relief and improved quality of life that often follow knee replacement. But now new research suggests that for some patients, knee replacement surgery can actually save their lives.

In a sweeping study of Medicare records, researchers from Philadelphia and Menlo Park, Calif., examined the effects of joint replacement among nearly 135,000 patients with new diagnoses of osteoarthritis of the knee from 1997 to 2009. About 54,000 opted for knee replacement; 81,000 did not.

Three years after diagnosis, the knee replacement patients had an 11 percent lower risk of heart failure. And after seven years, their risk of dying for any reason was 50 percent lower.
