Patients experienced significant post-THR improvements in Harris Hip scores , but this did not differ between impact types .
Recipients of cross-linked vs. conventional polyethylene cup liners experienced reduced femoral head penetration and revision .
There was no impact of femoral stem fixation and cup shell design on implant survival rates .
Evidence on mortality and complications ( aseptic loosening , femoral fracture ) was inconclusive .
BACKGROUND Evolvements in the design , fixation methods , size , and bearing surface of implants for  total hip replacement ( THR ) have led to a variety of options for healthcare professionals to consider .
The need to determine the most optimal combinations of THR implant is warranted .
This systematic review evaluated the clinical effectiveness of different types of THR used for the treatment of end stage arthritis of the hip .
Prospective, randomized comparison of cobalt-chrome and titanium trilock femoral stems.
The purpose of this article was to demonstrate the efficacy of a cementless , flat , tapered wedge femoral stem and compare cobalt-chrome and titanium femoral stems with this design . Three hundred ninety femoral stems observed for a mean of 4.7 years ( 2.0 - 8.9 years ) were prospect ively evaluated with clinical and radiographic follow-up . Hips were stratified by Dorr classification , bone stock ( femoral index ) , size of implant used , and material of femoral implant . Survivorship of the femoral stem at 8.9 years was 99.8 % with no significant difference between cohorts . Thigh pain ( 4.9 % ) was more common with cobalt-chrome femoral stems ( 6.5 % ) than titanium femoral stems ( 3.1 % ) . The flat , tapered wedge femoral stem design provides excellent femoral reconstruction in total hip arthroplasty . On the basis of this study , we use titanium femoral stems
