Randomized Controlled Trial Comparative Study
Postoperative autologous blood transfusion drain or no drain in primary total hip arthroplasty? A randomised controlled trial.
Postoperative maintenance of high haemoglobin (Hb) levels and avoidance of homologous blood transfusions is important in total hip arthroplasty (THA). The introduction of a postoperative drainage autologous blood transfusion (ABT) system or no drainage following THA has resulted in reduction of homologous blood transfusion requirements compared with closed-suction drains. The purpose of this study was to examine which regimen is superior following THA. ⋯ The use of a postoperative autologous blood retransfusion drain did not result in significantly higher postoperative Hb levels or in less total blood loss or fewer homologous blood transfusions compared with no drain.

Randomized Controlled Trial Comparative Study
Less wear with aluminium-oxide heads than cobalt-chrome heads with ultra high molecular weight cemented polyethylene cups: a ten-year follow-up with radiostereometry.
Wear is a major contributor to osteolysis and aseptic loosening of total hip replacements (THR). Both alumina (Al(2)O(3)) and cobalt-chrome (CoCr) femoral heads are commonly used. We investigated wear comparing alumina heads to cobalt-chrome heads against conventional cemented polyethylene (PE) cups for up to ten years. ⋯ Alumina heads performed better than cobalt-chrome heads in this study after ten-year follow-up.

Randomized Controlled Trial Comparative Study
Prospective randomised study comparing screw versus helical blade in the treatment of low-energy trochanteric fractures.
The purpose of this study was to compare femoral head placement, rates of reoperation and cephalic implant cut-out of a screw versus a blade for patients over age 60 with low energy trochanteric fractures (AO/OTA 31-A1, A2, and A3) treated either with sliding hip screw or cephalomedullary nail. ⋯ Both a screw and a blade performed equally well in terms of implant placement in the femoral head and outcome.

Randomized Controlled Trial Comparative Study
Unipolar hemiarthroplasty versus bipolar hemiarthroplasty in the most elderly patients with displaced femoral neck fractures: a randomised, controlled trial.
Hemiarthroplasty (HA) is generally considered to be the treatment of choice in the most elderly patients with a displaced fracture of the femoral neck. However, there is inadequate evidence to support the choice between unipolar HA or bipolar HA. The primary aim of this study was to analyse the outcome regarding hip function and health-related quality of life (HRQoL) in patients randomised to either a unipolar or bipolar HA. The secondary aim was to analyse the degree of acetabular erosion and its influence upon outcome. ⋯ Unipolar HA and bipolar HA appeared to produce equivalent clinical outcomes after one year, but the significantly higher incidence of acetabular erosion in the unipolar HA group may imply that bipolar HA should be the preferred treatment.

Randomized Controlled Trial
Intra-articular injection of tranexamic acid reduces not only blood loss but also knee joint swelling after total knee arthroplasty.
This is a randomised controlled trial to examine whether intra-articular injection of tranexamic acid (TXA) decreases blood loss, as well as reducing leg swelling after total knee arthroplasty (TKA). ⋯ The results revealed intra-articular administration of TXA decreased not only blood loss, but also knee joint swelling after TKA.
