Objectives: Total knee arthroplasty (TKA) has dramatically improved the quality of life of patients with end-stage arthritis, improving both their physical activity and functioning level. There are sufficient data illustrating the postoperative complications of patients with diabetes undergoing TKA. However, no satisfactory data exist illustrating the relationship of TKA on the glycosylated hemoglobin (HbA1c) levels in patients with type II diabetes postoperatively, which is the aim of this study. Methods: This retrospective cohort chart review study was conducted in King Abdulaziz Medical City, Riyadh, Saudi Arabia, where 308 individuals were included after applying the inclusion/exclusion criteria. The primary outcome was to establish if any association exists between type II diabetic patients and postoperative drop in HbA1c levels compared with nondiabetic patients. Results: The overall mean age was 65.5 years, and 67% of the total sample were patients with diabetes. Furthermore, 76% of the whole sample underwent unilateral knee surgery. The overall mean for pre- and post-HbA1c were 7.08 and 7.04, respectively. Conclusions: In our sample, there were more diabetic patients needing TKA than nondiabetic. It was also noticed that diabetic patients have a higher chance of undergoing bilateral TKA than unilateral when compared to nondiabetic patients, with both results being statistically significant. In addition, postoperative HbA1c level was significantly reduced in diabetic patients who underwent bilateral TKA when compared to diabetic patients who underwent unilateral TKA.
