Study backs knee, hip replacements for elderly

CHICAGO, July 14 (Reuters) - People age 75 or older recover just as well as younger patients from knee or hip replacements to correct the ravages of arthritis, researchers said on Monday.

The finding adds to a growing body of evidence that age is not a barrier to such surgery, though the investigators found that many patients are not well-informed about this. The poor, they said, are often shut out.

Dr. Mary Hamel and colleagues at Beth Israel Deaconess Medical Center in Boston said they reached the conclusions after looking at 174 patients with an average age of 75 who had severe osteoarthritis, some of whom had replacement surgery.

"Patients age 75 and older took about the same amount of time to return to regular activities as those age 65 to 74, with most patients requiring assistance with activities such as shopping and household chores for more than a month," the researchers wrote in their report, published in the Archives of Internal Medicine.

"None of these (surgical) patients died, 17 percent had postoperative complications and 38 percent had pain lasting more than four weeks following surgery," they added.

Because the study tracked some patients who were well into their 80s, the findings should help doctors and patients be better informed about the value such procedures, the authors said.

"Joint replacement surgery was not offered as a treatment option for many patients, suggesting that some physicians may not provide elderly patients with the opportunity to choose this effective treatment," the researchers wrote.

"Not surprisingly, patients who were more concerned about the risks of surgery and about a long surgical recovery were less likely to have joint replacements," they added.

Hamel's team also found it concerning that lower income patients often did not have the surgery, which "mirrors many other research findings of diminished access to joint replacement surgery and other effective treatments among patient with lower socioeconomic status."
