title: No need for routine closed suction drainage in elective arthroplasty of the hip: a prospective randomized trial in 104 operations.
abstract: BACKGROUND
  The purpose of this study was to determine the utility of closed suction drainage (CSD) in elective total hip arthroplasty (THA).
  
  
  METHODS
  We randomized 104 elective, consecutive THAs to receive drainage (53) or no drainage (51). 60 arthroplasties were cemented and 44 hybrid.
  
  
  RESULTS
  In the drainage group, 2 hematomas and 2 superficial wound infections occurred; there were no wound complications in the undrained group (p = 0.04). Patients receiving drainage had a greater reduction in hematocrit (10.4 vs 7.4) (p = 0.03), and longer hospital stay (5.1 days vs 4.7) (p = 0.01). At the 3-month follow-up, we found no deep wound infections in either group.
  
  
  CONCLUSIONS
  We no longer use CSD in elective, primary, routine THA.
