Dysglycemia and Arthroplasty Outcomes: A Review

Arthroplasty (ART) is a common surgery and it is on the rise worldwide due to increasing longevity and osteoarthritis. The effects of perioperative hyperglycemia on the outcomes are largely unknown and the current review aimed to assess the impact of perioperative hyperglycemia on ART outcomes. The literature in PubMed and Google Scholar was searched for relevant articles published in the last ten years up to February 2020. The keywords knee ART, hip ART, diabetes mellitus (DM) impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and impaired glycated hemoglobin (HbA1c)were used. Among the 113 articles retrieved, 34 full-texts were eligible, and only 21 studies (17 from the USA, three from Europe, and two from Asia) met the inclusion criteria for the systematic review. The authors' names, year of publication, country, type of study, number of patients, and duration of the study were reported. The studies reviewed showed high ART complication rates including infections, loosening, increasing severity and depth of infection, more pain, and higher costs with high perioperative hyperglycemia. The cut-off glycated hemoglobin values associated with complications ranged from 6.7 to >8.
