A dramatic increase in surgical knee replacement has some researchers concerned that the procedure may be misused.

The ratio of Medicare patients undergoing total knee arthroplasty (TKA) jumped 99.2% between 1991 and 2010, from 31.2 procedures per 10,000 Medicare enrollees to 62.1 procedures per 10,000 enrollees, according to a new study.

"The growth in TKA should prompt consideration of whether too many (or too few) of these procedures are being performed both in aggregate and among key patient subgroups defined by race, sex, or age," the authors wrote.

Total knee and hip replacement surgeries may temporarily increase a patient's risk of myocardial infarction during the period immediately after the procedure, researchers said.

The effect was greatest during the 6 weeks following total hip replacement surgery among patients aged 80 and older, who faced a 25.3% increased risk of suffering acute myocardial infarction, according to the study.

The risk was more pronounced in female patients of all ages, for which researchers reported a 21.7% heart attack risk increase compared with 12.8% for male patients.
