Abstract
Summary
Single use instrumentation had a significant reduction on OR Turnover time and instrument setup/clean up time compared to traditional instrumentation.
Introduction
Recently, focus has shifted to improving OR efficiency by surgeons and hospital admin. The purpose of this study was to determine the effect of traditional instrumentation vs. single use instrumentation (SUI) on OR efficiency in navigated primary TKA.
Methods
This prospective randomized study was conducted at a single center, community hospital by a single surgeon. Patients were split into two groups: Group 1 (Navigated Traditional (n=23)) and Group 2 (Navigated SUI (n=26)). Efficiency was examined by measuring specific time intervals based on milestones in the OR preparation, surgical procedure, and OR cleanup.
Results
Instrument set up time was reduced by an average of 8.5 minutes (min) in Group2 vs. Group1 (p=0.00). Patient set up took slightly longer in Group2 (1.47 min) but not statistically significant (p=0.50). Both groups had similar procedure time (p= 0.21) and patient OR Time (120 min for both groups p=0.93). Instrument clean up time was significantly shorter in Group 2 (difference 3.44 min (p=0.01). Overall surgical episode was significantly faster in the Group 2 by 9.57 min (p=0.02). Tourniquet time significantly reduced in the Group 2 by 4.92 min (p=0.02). Overall Instrument set up and clean up was faster by 11.94 min in Group 2 vs. Group 1. Notably, the OR turnover time was reduced by 23.52 min in the Group 2 vs. Group 1.
Conclusion
Single-use instruments had a significant reduction on OR Turnover time and instrument setup/cleanup time compared to traditional instrumentation. A larger prospective trial is warranted.
