Increased surgical time in TKA may impact economic costs and clinical outcomes. Prior work has found that TKAs in patients with high BMI take longer, and these patients may be at greater risk for postoperative complications like infection. However, these studies included small numbers of patients and surgeons from single institutions and they did not consider surgeon volume.

BMI 较高的患者进行全膝关节置换术是否需要更长的时间，这种差异是否与外科医生的手术量有关？来自国家关节置换术登记处的大型数据库研究。

TKA 手术时间的增加可能会影响经济成本和临床结果。先前的研究发现，高体重指数患者的全膝关节置换术需要更长的时间，而且这些患者发生感染等术后并发症的风险可能更大。然而，这些研究包括来自单一机构的少量患者和外科医生，并且没有考虑外科医生的数量。
