Obesity has previously been demonstrated to be an independent risk factor for increased complications following total hip (THA) and total knee arthroplasty (TKA). The purpose of this study was to compare the effects of obesity and BMI to determine whether the magnitude of the effect was similar for both procedures. We queried the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database to identify patients who underwent primary THA or TKA between 2010 and 2014. Patients were stratified by procedure and classified as non-obese, obese, or morbidly obese according to BMI. Thirty-day rates of wound complications, deep infection, total complications, and reoperation were compared using univariate and multivariate logistic regression analyses.Purpose
Materials & Methods
The purpose of this study was to evaluate trends in opioid use
after unicompartmental knee arthroplasty (UKA), to identify predictors
of prolonged use and to compare the rates of opioid use after UKA,
total knee arthroplasty (TKA) and total hip arthroplasty (THA). We identified 4205 patients who had undergone UKA between 2007
and 2015 from the Humana Inc. administrative claims database. Post-operative
opioid use for one year post-operatively was assessed using the
rates of monthly repeat prescription. These were then compared between
patients with and without a specific variable of interest and with
those of patients who had undergone TKA and THA.Aims
