Abstract

INTRODUCTION:

There has been an influx of research studies aimed at identifying all factors that contribute to minimizing cost and maximizing postoperative care after total knee arthroplasty (TKA). Length of stay (LOS) has been defined as a significant factor that contributes to increased burden. We aimed at looking whether day of surgery has any significant effect on the LOS and postoperative complications following total knee arthroplasty (TKA).

MATERIALS AND METHODS:

Retrospective cohort study done at the Aga Khan University Hospital, Pakistan, from January 2007 to December 2015. A total of 611 patients who underwent a unilateral or bilateral total knee arthroplasty (TKA) were included in study: 269 (44.0%) patients underwent unilateral TKA and 342 (56.0%) underwent a bilateral TKA.

RESULTS:

Kruskal-Wallis test and post hoc pairwise comparisons showed that unilateral TKAs performed on Tuesday, Saturday, and Sunday resulted in a lower median LOS (P < .05). No significant association was seen in bilateral TKA group. Day of surgery was not associated with postoperative complications.

CONCLUSIONS:

Unilateral TKAs performed earlier during the week and later on the weekend are associated with a significantly lower LOS. It is highly probable that patch ancillary services during the latter part of the week and a higher workload for the staff are important reasons for this phenomenon.
