“…The literature also supports the fact that there is no difference in the duration of hospital stay between these two groups, although the difficulty in positioning the patient, surgical exposure, and implantation have led to a higher incidence of operation time in the obese group, especially in morbid obese patients (21,25,26,30,31). It has been reported that the risk of deep infection is 3-9 times higher in morbid obese patients with TKA (5,8,9,22,32). In this study, the only patient who had a deep infection diagnosis postoperatively was in the obese group and was morbidly obese.…”

Hem obezitenin hem de total diz protezi (TDP) uygulamasının artışı ile birlikte, son yıllarda obez hastalarda TDP uygulama sayısı artmıştır. Obezitenin TDP uygulamasında izlenen komplikasyonlar için risk faktörü olup olmadığı tartışmalıdır. Bu çalışmanın amacı TDP uygulaması yapılan hastalarda intraoperatif ve erken postoperatif (hastanede) komplikasyonlar üzerine obezitenin etkisini araştırmaktır. GEREÇ VE YÖNTEM:Hastalar vücut kitle endeksine göre 2 gruba ayrıldı; Grup 1: obez (Vücut kitle endeksi: VKE > 30 kg/m2), Grup 2: Obez olmayan (VKE ≤30 kg/m2). Hastaların dosyaları 4 farklı yönden değerlendirildi (Demografik veriler; Preoperatif, İntraoperatif, Postoperatif bulgular). Parametrik verilerin analizinde T-test, non-parametrik verilerin analizinde Ki-kare testi kullanıldı. P<0.05 değeri anlamlı kabul edildi. BULGULAR:Obez olan ve olmayan hastalar arasında hastanede yatış, operasyon ve turnike süreleri, kan transfüzyonu sayısı, ASA (American Society of Anesthesiologists) puanları, İskemik kalp hastalığı, diyabet varlığı, lokal cilt komplikasyonları ve derin ven trombozu, sepsis, pulmoner emboli, mortalite gibi sistemik komplikasyonlar yönünden fark yoktu. Ancak obez grupta hipertansiyon, hipotiroidizm ve obstrüktif uyku apnesi istatistiksel olarak anlamlı oranda daha sık izlendi. SONUÇ:Obez olan ve olmayan hastalara uygulanan TDP olguları arasında lokal ve sistemik komplikasyonlar yönünden fark yoktur.

“…Studies have shown that for every 5 kg/m 2 increase in body weight, the risk of knee osteoarthritis increased by 35% [ 2 , 3 ]. However, it is controversial whether high BMI is a negative factor that affects the outcomes of primary TKAs [ 4 , 5 , 6 , 7 , 8 , 9 ]. A clinical study of 199 patients by Daniilidis et al showed no significant negative effect of obesity on outcomes after TKA [ 6 ].…”

“…A clinical study of 199 patients by Daniilidis et al showed no significant negative effect of obesity on outcomes after TKA [ 6 ]. In contrast, Başdelioğlu et al reported that obesity was one of the most critical risk factors for aseptic prosthetic loosening [ 4 ], which was one of the most common and severe complications after TKA, accounting for 29.8% of revision surgeries [ 10 , 11 ]. It is necessary to figure out the effect of BMI on the aseptic loosening of the knee prosthesis.…”

“…The direct and indirect effects of obesity imply that patients with a higher BMI should have worse postoperative alignment after TKA, resulting in worse long-term function and lower prosthesis survival rates ( 6 , 9 ). However, there is no definitive BMI cutoff that accurately separates high-risk patients from low-risk patients.…”

Background: A high body mass index (BMI) is associated with increased rates of complications after total knee arthroplasty (TKA). However, no study has examined the effect of BMI on lower limb alignment using the World Health Organization's (WHO) BMI classification. We believe that the WHO's BMI classification allows a uniform standard worldwide. We sought to investigate the potential association between a high BMI and the incidence of postoperative misalignment. We also evaluated whether a higher BMI is associated with worse clinical function. Methods:We retrospectively reviewed the data of 671 patients who underwent primary TKA for varus osteoarthritis between January 2010 and December 2015. The patients were divided into the following 5 groups based on their BMI: normal weight (<25.0 kg/m 2 ), overweight (25.0-29.9 kg/m 2 ), class I obese (30.0-34.9 kg/m 2 ), class II obese (35-39.9 kg/m 2 ), and class III obese (>40 kg/m 2 ). Both weight and height were measured by nurses on admission. Patients' preoperative HKA, gender, age, and side of surgery were collected as baseline. All the patients underwent standing, weight-bearing, full-length radiography before and after surgery to measure the mechanical hip-knee-ankle angle (HKA). We followed up patients by telephone.Among the BMI subgroups, we compared the knee function scores, including the Western Ontario andMcMaster Universities Osteoarthritis Index (WOMAC) score, Knee Society-Knee Score (KS-KS), Knee Society-Function Score (KS-FS), Forgotten Joint Score (FJS), and range of motion (ROM). A multivariate linear regression analysis and a logistic regression was conducted to examine the outcomes. Results:The study had a mean follow-up period of 8.16 years. The multivariate and logistic regression analyses revealed that preoperative alignment (P=0.002) and a higher BMI (P=0.015) were associated with a higher risk of postoperative misalignment. The WOMAC scores were higher in the normal and overweight groups than the other groups (P=0.022). The FJS and KS-KS gradually decreased as BMI increased.Conclusions: A higher BMI is associated with a greater risk of misalignment and worse long-term clinical outcome after TKA. When treating patients with high BMI, we should pay more attention to the adjustment of lower limb alignment intraoperatively.
