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 .
Comparison of total hip arthroplasty performed with and without cement: a randomized trial. A concise follow-up, at twenty years, of previous reports.
Total hip arthroplasty has been associated with excellent implant survival rates , but debate remains concerning the best fixation method for the components . A r and omized controlled trial , which included 250 patients ( mean age , sixty-four years ) with osteoarthritis who were managed with total hip arthroplasty between October 1987 and January 1992 , was conducted to compare the results of fixation with and without cement .  Patients were followed for a mean of twenty years ( range , seventeen to twenty-one years ) .  Kaplan-Meier survivorship analysis at twenty years revealed significantly lower survival rates for cemented implants as compared with cementless implants . The cementless tapered stem had an extremely good survival rate of 99 % . Radiographs showed evidence of mild stress-shielding around 95 % of the cemented stems and 88 % of the cementless stems ; stress-shielding of grade 3 or greater was seen around the remaining 12 % of the cementless stems
