Patients in this study with hypertension who underwent total knee replacement reported increased physical activity and reduced systolic and diastolic blood pressure, but patients with type II diabetes mellitus in the same study did not have reduced blood glucose level.

“Our study showed increased physical activity postoperatively, and reduction in systolic and diastolic blood pressure, though this cannot be attributed entirely to increased physical activity,” the researchers wrote in the study. “Reduced dependence on [non-steroidal anti-inflammatory drugs] NSAIDs may have also acted as a contributor.”

Researchers from India prospectively enrolled 55 patients with type II diabetes mellitus and 65 patients with hypertension in this study, according to the abstract. All patients underwent total knee replacement to treat tricompartmental osteoarthritis.

Researchers measured the Knee Society Score (KSS), lower extremity activity scale, fasting blood glucose level and systolic and diastolic blood pressure of patients both preoperatively and postoperatively. KSS increased from 29 points preoperatively to 86 points postoperatively in patients with diabetes and their lower extremity activity scale scores increased from 6.7 points to 11.3 points preoperatively and postoperatively, respectively.

Patients had a statistically significant decrease of 8-mm Hg for systolic and 6-mm Hg for diastolic blood pressure levels. However, no patients in either group had reduced fasting blood glucose levels, according to the abstract.
