Prospective, randomized trial. 40 patients who underwent revision hip arthroplasty, divided in to two groups with or without drainage. All patients was assessed with ultrasonography on 3rd day after surgery. Bleeding, need for blood transfusion and laboratory test was analyzed after surgery. Patients was assessed with Harris Hips Score and Visual Analog Scale after surgery.

Inclusion criteria: aseptic loosening, head or insert damage, girdlestone hip. Exclusion criteria: septic loosening, primary or secondary coagulopathy, renal or hepatic failure, thromboembolism in past history. At the end of operation information of drainage was get out from the envelope. On 3rd day all patient get ultrasonography with level of fluid in the joint and hematoma in soft tissue measurement. We analyzed hemoglobin, C-reactive protein, erythrocyte sedimentation rate on 1st and 3rd day after surgery. Visual analog scale was taken on 3rd day after surgery and Harris Hip Score 6 weeks after.
