The relationship between obesity and the age at which hip and knee replacement is undertaken

Abstract

We audited the relationship between obesity and the age at which hip and knee replacement was undertaken at our centre. The database was analysed for age, the Oxford hip or knee score and the body mass index (BMI) at the time of surgery. In total, 1369 patients were studied, 1025 treated by hip replacement and 344 by knee replacement. The patients were divided into five groups based on their BMI (normal, overweight, moderately obese, severely obese and morbidly obese). The difference in the mean Oxford score at surgery was not statistically significant between the groups (p > 0.05). For those undergoing hip replacement, the mean age of the morbidly obese patients was ten years less than that of those with a normal BMI. For those treated by knee replacement, the difference was 13 years. The age at surgery fell significantly for those with a BMI > 35 kg/m(2) for both hip and knee replacement (p > 0.05). This association was stronger for patients treated by knee than by hip replacement.

Hip osteoarthritis surgical profiles and morbid obesity: a case series and literature review

“…This subgroup is also at risk for severe complications such as infection. This is consistent with Changulani et al [8] who found those in the morbidly obese range were almost 10 years younger on average than those in the normal weight category, and those with higher body weights were more likely to experience adverse surgical outcomes than those who were not. This also accords with Tai et al [9] and with Guetner et al [10].…”

Bariatric Orthopaedics: Total Knee Arthroplasty in Super-obese Patients (BMI > 50 kg/m2). Survivorship and Complications

“…Obese patients appear to undergo TKAs at younger ages, and those reconstructions may be associated with lower implant survivorship [6,36]. In addition, arthroplasties may be more technically demanding in these patients as a result of difficulty in identifying the anatomic landmarks.…”

“…It is associated with an increase in medical comorbidities including hypertension, coronary artery disease, diabetes, and degenerative joint disease [7,32]. These patients potentially may be at increased risk for having osteoarthritis develop, and may need TKA at an earlier age [6,26]. However, surgical interventions in these patients may be associated with more technically demanding procedures and higher complication rates [3].…”

The effect of body weight on the choice of material for the bearing couple in artificial hip joints

“…По статистике па-циенты с ИМТ > 35 кг/м 2 предпочитают пройти операцию по поводу ОА в более раннем возрасте [22]. Причины этого явления многофакторны, но вероятно, тучные пациенты при остеоатрите ищут радикальный и более быстрый вариант ре-шения проблемы, чем пациенты с нормальным ИМТ.…”
