“…Studies focusing on the obese patient population show most patients show improvements in outcome scores and are satisfied with TKA [1,2,12,18,19,24,26,30,33,37,43,44,48,49]. However, high body weight amplifies the magnitude of joint load per step and may adversely affect polyethylene wear performance and the rate of aseptic loosening.…”

Background In the United States, the obese population has increased markedly over the last four decades, and this trend continues. High patient weight places additional stress on TKA components, which may lead to increased polyethylene wear, osteolysis, radiolucencies, and clinical failure. Metalbacked tibial components and all-polyethylene tibial components in the general population have comparable osteolysis and failure, but it is unclear whether these components yield similar osteolysis and failure in obese patients.Questions/purposes We therefore determined the (1) function, (2) occurrence of osteolysis, and (3) complications in a cohort of obese patients receiving allpolyethylene tibial components.

“…Moreover, the role of baseline factors such as age, mental health status, comorbidity, body mass index (BMI), and patient expectations in explaining gender differences in patient-reported outcome measure (PROM) scores is not well known. Because these factors are themselves typically correlated with PROM scores [12,26,28,39] and may differ between men and women preoperatively, they represent potential confounding effects in any analysis of gender differences in PROM scores.…”

Background Many studies report differences in patientreported outcome measures (PROMs) for men and women undergoing total hip arthroplasty (THA). Few studies have evaluated whether these are explained by corresponding differences in important preoperative factors. Questions/purposes (1) Are there differences between men and women in PROM scores preoperatively and 12 months after THA? (2) Do baseline differences in comorbidity, age, body mass index (BMI), and mental health status explain these differences in PROM scores? Methods Preoperatively, 300 patients completed the Oxford Hip Score (OHS), WOMAC, and SF-12; 261 (86%) of them (129 women, 64 ± 11 years; 132 men, 66 ± 10 years) completed the same questionnaires 12 months postoperatively and also rated the acceptability of their current symptoms and change in general health. Results Preoperatively, women showed worse scores than men in the OHS (À1.9; 95% confidence interval, À3.6 to À0.3) and WOMAC (À6.3; À10.9 to À1.7). At 12 months postoperatively, the absolute scores for all PROMs were not significantly different. After controlling for BMI, age, comorbidity, SF-12 mental health scores, and sociodemographic characteristics, the baseline differences remained. Conclusions Surgeons may be more reluctant to operate on women than men because they perceive that, because of their worse baseline status, women are likely to have worse outcomes; however, given that we found no evidence for differences in patient-reported outcomes at 12 months, these suspicions would appear to be unfounded. Women and men can be expected to benefit to a similar extent from THA. Level of Evidence Level III, therapeutic study.

“…On the other hand evidence suggests that there is no significant long-term difference in parameters like patient satisfaction [18], post-operative pain [15], aseptic loosening (despite a different load) [5,17] and 10-year survival rates [9] between obese and non-obese patients having a joint replacement. There does not seem to be any conclusive evidence about a higher rate of surgical and non-surgical complications between patients who are obese and those who are not obese [9,10,14,15].…”

The purpose of this study was to evaluate the relationship between body mass index and early complications following total hip replacements. Five hundred and fifty patients who underwent primary total hip replacement were recruited. All these patients were subjected to a pre-operative assessment and follow-up at 6 weeks and 1 year following surgery. Any complications occurring during this period were recorded. Complications were grouped into systemic and local, both subdivided into minor and major depending on the risk involved. Fifty-six patients (10.2%) had an early complication following hip replacement surgery. Forty-four patients (8%) had a major local complication. Overall, there did seem to be a weak correlation between BMI and the rate of complications, with a p value of 0.104. A correlation was also found between the surgeon and presence of complications with a p value of 0.736. There is a weak correlation between BMI and early complications following hip replacement surgery, and there also seems to be a correlation between the operating surgeon and early complications, but this is not statistically significant.Résumé Le propos de ce travail est d'évaluer la relation du BMI et des complications précoces pour les prothèses totales de hanche. Méthode: 550 patients ayant bénéficié d'une prothèse totale de hanche ont été évalués. Tous ces patients ont été analysés en préopératoire et à six semaines et un an de recul, après l'intervention. Toutes les complications survenant durant cette période ont été analysées. Les complications ont été groupées en complications générales et complications locales de même elles ont été également divisées en complications mineures et majeures. Résultat: 10.2% des patients (n=56) ont présenté une complication précoce après prothèse totale de hanche, 8% (n=44) ont présenté une complication majeure. Le BMI semble être en corrélation avec le taux des complications de même une corrélation a été trouvée également entre le chirurgien et les complications. En conclusion: le BMI a une corrélation avec les complications précoces après prothèse totale de hanche. Il en est de même en ce qui concerne l'équipe chirurgicale mais pas de façon satistiquement significative.
