PASADENA, Calif., Feb. 27, 2013 Patients with diabetes who undergo total knee replacement surgery do not have increased risk of surgical complications compared to those patients without diabetes, according to a Kaiser Permanente study published today in The Journal of Bone and Joint Surgery.
Researchers studied the electronic health records of more than 40,000 patients who had a first-time knee replacement from January 1, 2001 through December 31, 2009. Of the patients studied, 12.5 percent had controlled diabetes, 6.2 percent had uncontrolled diabetes and 81.3 percent did not have diabetes. In contrast to the findings of previous studies, researchers on this study found those with controlled and uncontrolled diabetes who underwent a total knee replacement were at no increased risk of complications such as follow-up surgery (also known as revision arthroplasty), deep infection, or blood clots in the legs or lungs, when compared to patients without diabetes.
"We are fortunate to do our research in a real-world setting that helps us to find real-world solutions for our patients," said Annette L. Adams, PhD, MPH, of the Kaiser Permanente Southern California Department of Research & Evaluation. "This current study suggests that patients with diabetes who have higher glucose levels may not be at greater risk of poor surgical outcomes. This finding will help physicians and their patients with diabetes make better informed decisions about total knee replacement as an option."
Adams also noted that one of the elements that differentiated this study from previous research was that the Kaiser Permanente patients with diabetes had better glycemic control than previous study populations. "We have good quality of care, and good chronic disease management," Adams said, "and in this setting, glycemic control had little impact on the outcome of total knee replacement surgery."
The study also found that among the approximately 28 perc
