“…Mean operative time in this national, multi-institutional cohort of 4,782 patients was 8:31 hours:minutes (SD: 2:59), which is similar to, or slightly longer than, the mean operative times reported in single-institution, presumably "expert" series, which ranged from 3:21 to 8:30 hours:minutes. [37][38][39] Average unilateral duration was 8:14 hours:minutes, while average bilateral duration was 9:05 hours:minutes. In case series reports, bilateral cases were approximately 2.5 hours longer than unilateral cases.…”
