Here is the GrAbstract of the study: This study is of great importance because it is the largest non-registry based study investigating what sort of trends the number of revision surgeries […]

Metal-on-metal hips on the Gartner Hype Cycle

Therefore two other later stages are proposed with annotations. Reference 1. Harris WH. Osteolysis and particle disease in hip replacement. A review. Acta Orthop Scand. 1994 Feb;65(1):113-23. 2. […]

There has been relative paucity in the literature regarding positive studies in MoM HRs. Some single surgeon and single center studies have been published, but in general, the study by Hellman […]
