The independent impact of individual surgical experience and team familiarity on surgical performance has been widely studied; however, the interplay of these factors and their relative, quantified, contributions to performance is poorly understood. We determined the impact of team familiarity and surgeon, and cumulative team experience on operative efficiency in total knee replacement. ⋯ Surgical experience and team familiarity display important and distinct relationships with operative time in total knee replacement. Appreciation of this interplay may serve to guide implementation and allocation of procedure-specific quality improvement strategies in surgery.
