Use of Redon drains in primary total hip arthroplasty has no clinically relevant benefits.

Although no proven evidence exists for the use of drainage in primary total hip arthroplasty, such drainage is routinely used. This prospective, randomized study comprised 80 patients who underwent a non-cemented total hip arthroplasty using a minimally invasive anterolateral approach. Patients were divided into 2 groups of 40: group 1 underwent drainage treatment and group 2 underwent no drainage treatment.
