A new study by the Journal of Bone and Joint Surgery has found that the risk of mortality in knee replacement surgery is even lower than previously thought.
The study, which encompassed 81,856 patients in Norway, furthers the notion that knee replacement surgery is one of the most successful surgery procedures carried out today. The danger of death estimated by the study was pegged at less than 0.1%. The vast majority of patients who undergo total knee replacement surgery experience an improved lifestyle and mobility, with significantly reduced pain.
“Previous studies suggesting that increased mortality exists for as long as 60 or 90 days post hip or knee replacement surgery may be wrong,” said Stein Atle Lie, PhD, MSc, lead author of the study. “We believe the risk is tied to a much shorter duration.” The rare cases in which complications occur, the study indicates, are usually during or shortly after surgery.
The data gathered from this study “should be reassuring for patients considering these surgeries,” said Lars B. Engesaeter, MD, PhD, co-author of the study. Knee replacement surgery has been common practice for decades, and the surgical methods used have advanced to such a state that it is one of the safest surgical procedures performed in modern medicine.
