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 surgical outcomes and implant wear between ceramic-ceramic and ceramic-polyethylene articulations in total hip arthroplasty.
The results of a prospect i ve multicenter trial comparing 357 hips r and omized to total hip arthroplasty with either ceramic-ceramic or ceramic-polyethylene couplings  are presented . No statistically significant difference in clinical outcomes scores between the ceramic-ceramic and ceramic-polyethylene groups was observed at any time interval . The mean linear rate was statistically lower ( P < .001 ) in the ceramic-ceramic group ( 30.5 μm/year ) when compared with the ceramic-polyethylene group ( 218.2 μm/year ) . The rates of ceramic implant fracture ( 2.6 % ) and audible component-related noise ( 3.1 % ) were statistically higher in the ceramic-ceramic group when compared with the ceramic-polyethylene group ( P < .05 ) . Lastly , there was no statistically significant difference in the dislocation or revision rate between the groups at the time of last clinical follow-up
