Background:
The purpose of this study was to determine the utility of closed suction drainage (CSD) in elective total hip arthroplasty (THA).
Patients And 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.
Interpretation:
We no longer use CSD in elective, primary, routine THA.
