From: Lower limb orthopaedic surgery results in changes to coagulation and non-specific inflammatory biomarkers, including selective clinical outcome measures

  THR (preoperatively) THR (day 3 postoperatively) TKR (preoperatively) TKR (day 3 postoperatively)
Blood agar Negative Negative Negative Negative
MacConkey Negative Negative Negative Negative
Anaerobic medium Negative Negative Negative Negative
Staphylococcus selective agar Negative Negative Negative Negative
Streptococcus selective agar Negative Negative Negative Negative
  1. Wound swabs were collected and assessed for evidence of infection at the site of surgery. Swabs were collected pre and post THR and TKR surgery (day 3 postoperative). Swabs were incubated for 48 hour periods on blood agar, MacConkey agar, anaerobic medium and agar selective for Staphylococcus and Streptococcus.
