Characteristics and complications of super-obese patients who underwent total knee arthroplasty

Preoperative demographic characteristics comorbidities length of stay and surgery and postoperative complications were compared between super-obese (n=1042) and nonobese (n=19,929) patients who underwent total knee arthroplasty. Superobese patients were younger were predominantly women had an increased incidence of comorbid conditions such as diabetes and hypertension as well as a high rate of superficial and deep wound infections and had a longer mean length of stay and operative time. Although superobese patients have unique demographic characteristics and increased postoperative complications and length of stay they may still benefit from total knee arthroplasty. Surgeons should note their high incidence of infections.
