Delineating the impact of obesity and its relationship on recovery after total joint arthroplasties

摘要: Summary Objective The primary aim of this study was to determine the impact obesity in predicting short and long-term pain relief functional recovery total joint arthroplasty (TJA) either as an independent risk factor or a mediated by two chronic conditions associated with obesity-cardiac disease diabetes mellitus. Method A prospective observational 520 patients arthroplasties. Pain outcomes were evaluated Western Ontario McMaster Universities (WOMAC) Osteoarthritis Index within month surgery then 6months 3years post-operatively. Obesity, cardiac mellitus examined potential factors for poor recovery. Patients classified into four groups based on body mass index (BMI): (normal 2 ; overweight 25.0–29.9 kg/m obese Class 1 30.0–34.9 kg/m severe 2&3 35.0 ≥ kg/m ). Linear mixed models each type (hip knee arthroplasty) developed examine pattern effect obesity. Results Ninety-nine (19%) severely obese, 127 (24%) had 58 (11%) Baseline scores similar regardless BMI classification. Severe significant worse at but no longer following hip arthroplasty. Cardiac predicted slower after No interactions existed between Discussion is slow over both
