A new study finds elderly patients who undergo the procedure are at a greater risk of stroke in the first few weeks after their surgery.
Authors say their findings in the journal Stroke suggest that elderly people need to weigh the benefits of hip replacement against the risk of stroke.
The average age of the patients in the study was 72.
Investigators also found the risk of stroke stayed higher up to 12 weeks after surgery. They also determined that taking aspirin lowered the stroke risk by as much as 70 percent.
