Effect of Surgical Start Time on Length of Stay, Morbidity Rate, and Surgical Risk in Elective Total Hip Arthroplasty
$25.00
There is conflicting literature regarding the effect of surgical start time for total hip arthroplasty (THA) on morbidity. This study examined outcomes between start time groups in elective THA. A retrospective review identified patients undergoing elective cementless primary THA between 2009 and 2019. Patients were divided into morning or evening start time groups. Chi-squared analysis and independent sample t-tests were run to detect differences between groups in matched and unmatched analysis. Five hundred fifteen patients were identified based on selection criteria. Chi-squared analysis and independent sample t-tests identified no significant differences in duration of surgery, estimated blood loss, length of stay, or other complications between start time groups. This study provided clinical data over a 10-year period supporting that surgical start time in elective THA does not have a significant impact on outcomes.
