T1 What’s New in Total Hip Arthroplasty JF The Journal of Bone & Joint Surgery JO The Journal of Bone & Joint Surgery YR 2012 FD September 19 VO 94 IS 18 SP 1721 OP 1727 DO 10.2106/JBJS.L.00620 UL http://dx.doi.org/10.2106/JBJS.L.00620 AB Total hip arthroplasty remains one of the most effective and safe orthopaedic reconstructive procedures. A major focus over the past year has been the controversies regarding the safety of metal-on-metal articulation couplings and the associated adverse tissue reactions. Another area of focus has been on the outcome measures and practice protocols developed with evidence-based criteria. We have also included selected citations from the most recent published and presented data on the clinical outcomes and treatment of complications following total hip arthroplasty.
