Body mass index (BMI) is a topical area of interest in the field of lower limb arthroplasty. It has been well established that BMI can influence post-operative outcomes. This study compares post-operative outcomes, including satisfaction rates, length of stay (LOS) and radiographic findings in different BMI groups following total hip arthroplasty (THA). We retrospectively evaluated all non-navigated THAs performed at our institution from 2006–2016. Case-notes were reviewed for dichotomised satisfaction score, LOS and radiographic parameters including inclination, anteversion, limb length discrepancy (LLD) and offset discrepancy. Patients were classified into 4 groupings based on BMI (underweight (<24.5), healthy (24.5–30), obese (30–40), severely obese (>40)). Appropriate statistical analyses were performed to identify between group differences.Introduction
Methods
Surgical site infection (SSI) remains a concern following total hip arthroplasty (THA). We aimed to identify risk factors for post-operative SSI in THA. All primary THAs performed in our institution during 2009–2010 were included, giving 1832 cases in 1716 patients. Cohort demographics were mean age 67.9 years (SD10.2), mean BMI 29.6 (SD5.3), 60% female and 90.2% primary indication of osteoarthritis. Post-operative SSI within one year was identified either through hospital infection control records or from Information Services Division (NHS Scotland). Demographic and peri-operative data for known or suspected risk factors for SSI were collected from clinical records. Groups were compared using independent t-tests and chi-squared tests as appropriate.Introduction
