Diabetes “Diabetes Mellitus”: Can the Disease Affect Total Knee Replacement Surgery Outcomes?

Diabetes is one of the commonest medical condition among men and women, both in India and worldwide. Due to the escalating incidence of the disease among individuals and the necessity for knee arthroplasty, it became a major concern for researchers to evaluate the two sides. That is; the Diabetes Mellitus side and total knee replacement.

Why Was the Research Conducted?

Total knee replacement is a complex procedure and certainly, just like any other surgery, knee replacement can cultivate additional risks for diabetic patients. Imagine, preparation for knee arthroplasty requires a dental checkup to outrule any underlying infection, then what about diabetes?

According to a 2009 Study & One in 2014

Both studies found that diabetic patients face an escalated chance of complications after knee replacement. The study moved on to stress that this is most especially when the blood sugar levels aren’t well monitored and controlled.

With that, diabetes can certainly increase the risk of infection, fracture around the implant and joint loosening. Moreover, researchers found that deep vein thrombosis (DVT) and strokes are more common in diabetic patients during the post-surgical period.

According to a 2013 Study

This study concluded with its own suggestions, certainly contradictory to the study above. The study considered data from  atleast 40,000 patients and the conclusions stressed no difference in surgical complications between diabetics and other patients without diabetes.

Researchers in this study also concluded that blood sugar control may not be a vital aspect for successful knee replacement. According to the study, patients with uncontrolled diabetes weren’t more likely to suffer from any negative surgical outcome than those patients with well-controlled diabetes.

However, the study also confirmed that obesity could be the reason behind the escalated complications in some diabetes patients. It declared that heavier patients have an increased chance of suffering from an infection, deep vein thrombosis (DVT), and less surgical outcomes. In addition, diabetes with obesity can increase the risk of these complications.


As per the given studies above, we are certain of the mixed findings of the research, but the fact remains that there is a link between diabetes and the possible knee replacement outcomes.

We are also sure that more research is required to ascertain how diabetes and blood sugar control affect knee arthroplasty outcomes. With that, orthopaedic surgeon must be keen during preparation and abide with safety measures that can reduce the chance of complications in diabetics. A patient must be thoroughly evaluated before Knee Replacement Surgery in India to bypass the would-be complications.

Certainly, there is a degree of inflammation that is cultivated during surgery and this can be worsened after the surgery in diabetics. Likewise, all other complications are much likely to occur in diabetics after knee replacement.

With that, strict measures on how to control the blood sugar levels are necessary. In case possible, losing weight prior to the surgery can eliminate the effects associated with the extra pounds on surgical outcomes.
