A substantial proportion of TKA candidates have diabetes mellitus, which is associated with increased perioperative risk. Prior studies have largely focused on preoperative hemoglobin A1c (HbA1c), while the effect of postoperative glycemic control on complication rates remains less well-defined. This study evaluated the relationship between late postoperative HbA1c levels and postoperative complications following TKA. A propensity score-matched retrospective cohort study was performed using the TriNetX multi-institutional database. Adults aged 18 to 90 years who underwent primary TKA with documented HbA1c &gt;\u20098% for 3 months preoperatively, who were able to decrease it to under 7.5% for &lt;\u20093 months preoperatively. HbA1c values obtained 1 to 2 years postoperatively were used to define cohorts: Cohort 1 (HbA1c &lt;\u20097.5%) and Cohort 2 (HbA1c \u2265\u20098.0%). Outcomes included early medical complications (30 and 90 days) and arthroplasty-specific complications within 5 years, including periprosthetic joint infection, revision surgery, mechanical loosening, and periprosthetic fracture. After matching, a total of 3,200 patients met the inclusion criteria, with 1,600 patients in each cohort after matching. There were no significant differences in 30- or 90-day medical complications between groups. At 5 years, rates of periprosthetic joint infection, revision surgery, mechanical loosening, and periprosthetic fracture were also similar. Elevated postoperative HbA1c at 1 to 2 years following TKA was not independently associated with increased risk of complications or implant failure when perioperative glycemic control was optimized. These findings suggest that once early healing occurs under adequate glycemic conditions, later deterioration in glycemic control may have a limited impact on arthroplasty outcomes.<\/jats:p>","DOI":"10.1055\/a-2968-6258","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T23:18:14Z","timestamp":1790637494000},"source":"Crossref","is-referenced-by-count":0,"title":["Postoperative
