Surgical site infection (SSI) is a disastrous complication after total knee arthroplasty (TKA) which can cause prosthesis loosening and may end up in septicaemia. The incidence of infection reported to be in the range of 0.3-12.4% for primary TKA. Significantly higher infection rate is found in the morbidly obese patients. The current study compared the immediate rate of post-total knee replacement wound infection in the obese versus non-obese population. The cross-sectional study was conducted at Aga Khan University Hospital (AKUH) and comprised patients undergoing TKA for primary knee osteoarthritis. Surgical outcome was measured by the Southampton wound infection score at 1-month follow-up. Out of 142 enrolled patients with a mean age of 67.8±56 years, infection was confirmed in 3(2.11%) patients who needed surgical management. All the patients who developed SSIs were females.
