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 .
Methods and processes of the CONSORT Group: example of an extension for trials assessing nonpharmacologic treatments.
BACKGROUND The conduct of r and omized , controlled trials of nonpharmacologic treatments presents specific challenges that are not adequately addressed in trial reports . OBJECTIVE To develop an extension of the CONSORT ( Consoli date d St and ards of Reporting Trials ) Statement for trials of nonpharmacologic treatments . DESIGN A consensus meeting was organized to develop an extension of the CONSORT Statement that addresses r and omized trials of nonpharmacologic treatments . To prepare for the meeting , a survey was conducted to identify the specific issues for discussion . SETTING Consensus meeting in Paris , France . PARTICIPANTS A total of 33 experts attended the meeting . The experts were method ologists ( n = 17 ) ; surgeons ( n = 6 ) ; editors ( n = 5 ) ; and clinicians involved in rehabilitation ( n = 1 ) , psychotherapy ( n = 2 ) , education ( n = 1 ) , and implantable devices ( n = 1 ) . MEASUREMENTS Experts indicated which of the 22 items on the CONSORT checklist should be modified or which additional items should be added specifically for nonpharmacologic treatments . During a 3-day consensus meeting , all items were discussed and additional method ological issues related to nonpharmacologic research were identified . RESULTS The consensus was that 11 items on the CONSORT checklist needed some modifications for nonpharmacologic trials : item 1 ( title and abstract ) , item 3 ( participants ) , item 4 ( interventions ) , item 7 ( sample size ) , item 8 ( r and omization ) , item 11 ( blinding ) , item 12 ( statistical methods ) , item 13 ( participant flow ) , item 15 ( baseline data ) , item 20 ( discussion : interpretation ) , and item 21 ( generalizability ) . In addition , the meeting participants added 1 item related to implementation of the intervention . LIMITATION Evidence was not always available to support the inclusion of each checklist item . CONCLUSION The methods and processes used to develop this extension could be used for other reporting guidelines . The use of this extension to the CONSORT Statement should improve the quality of reporting r and omized , controlled trials assessing nonpharmacologic treatments
