The purpose of this study was to evaluate the relationship between body mass index and early complications following knee replacement.
Five hundred and twenty-seven patients who underwent primary knee 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 complication occurring during this period was recorded. Complications were grouped into systemic and local, minor and major.
12.1% (N = 64) patients had an early complication following knee replacement surgery; 9.2% (N = 48) patients had a major complication. Overall BMI did not seem to influence significantly the rate of complication with a P-value of 0.338. A stronger correlation was found between the surgeon and presence of complication with a P-value of 0.004.
BMI has a weak correlation to early complications following joint replacement surgery. The operating surgeon seems to have a stronger correlation to early complications as compared with BMI.
本研究旨在评估体重指数与膝关节置换术后早期并发症之间的关系。
招募了527例行初次膝关节置换术的患者。所有这些患者均接受了术前评估，并在术后6周和1年进行随访。记录在此期间发生的任何并发症。并发症分为全身和局部、轻微和严重。
12.1%（N = 64）的患者在膝关节置换术后出现早期并发症；9.2%（N = 48）的患者出现严重并发症。总体体重指数似乎对并发症发生率没有显著影响，P值为0.338。发现外科医生与并发症的发生之间存在更强的相关性，P值为0.004。
体重指数与关节置换术后早期并发症的相关性较弱。与体重指数相比，手术医生与早期并发症的相关性似乎更强。
