The Hard on Hard Bearings in THA – Current concepts [PDF]
Total hip arthroplasty has been one of the most successful inventions of the last century with useful results in decreasing pain and improving function in patients with degenerative disease of the hip. Improvements in prosthetic materials, designs and implant fixation have now resulted in wear of the bearing surface being the limitation of this ...
