[FONT="]Obesity: A global epidemic that poses challenges for total joint replacement

[FONT="]ORLANDO, Fla. — Total joint arthroplasty in obese patients will continue to be an important challenge for orthopedic surgeons as obesity rates are at their highest in 30 years and doubled in the last 20 years among U.S. adults, based on data presented at the Current Concepts in Joint Replacement 2011 Winter Meeting, here. “If you think that [obesity] is a U.S. trend, that is wrong,” Steven J. MacDonald, MD, FRCS(C), said in his presentation. “Most countries are in the clear double digits and many not that far off,” in terms of national obesity rates, he said. Patients with class 3 obesity, where body mass index (BMI) is greater than 40, have an 8.5 times higher risk of needing total hip arthroplasty (THA) and a 32 times higher risk for a total knee arthroplasty (TKA) compared with patients with normal BMI, according to MacDonald. “Obesity in total joint arthroplasty — it increases the number of procedures and the burden. There are increased complication rates,” he said. Infection is a one challenge, MacDonald noted. “Most series powered enough will start to show the trend of increasing infection rates, both superficially — and sometimes deep — with the morbidly obese patient,” he said. However, the difficulty of performing THA or TKA in obese patients is unquestioned, MacDonald said. “There is no evidence that obesity affects implants or survivorship,” he said, noting this may be because obese patients put their prostheses through fewer cycles per year on average. Based on changes between preoperative and postoperative WOMAC, SF-12 and the Hip Society Scores for THA in obese vs. normal weight patients that MacDonald and colleagues studied, “The procedure is doing what it is meant to do,” MacDonald said.
