Nth conclusion about hip resurfacings

It can´t be argued that the theoretical premises of hip resurfacing arthroplasty would not have been truly great. What could sound any better than “restoring native anatomy and hip biomechanics”? As we know, everything went a different road. Clough & Clough outlined quite accurate statement about hip resurfacings: Whilst MoM HRA can, in very limited […]

Benefits of hip resurfacing

I outlined some recent perspectives about hip resurfacing in a post almost two years ago. These perspectives are still well supported as the findings by McLawhorn et al. show. They performed a propensity-score matched analysis between THA and hip resurfacing in “appropriate” patients. They conclude: HRA may provide a functional benefit in sports and recreation […]

Declining incidence of MoM revision surgeries

Our recent study investigating annual trends of revision surgeries in patients with MoM hip replacements was recently published in the Journal of Arthroplasty (www). 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

This post describes an adaptation of Gartner Hype Cycle on metal-on-metal hip replacements. It is very unlikely that MoM hip replacements will achieve the “Plateau of Productivity“. 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. […]

Metal-on-metal hip resurfacings and the year 2019

Hellman et al. addressed the proposed advantages of metal-on-metal (MoM) hip resurfacings (HR) over tradition total hip replacements (THR) in their recent systematic review. 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 […]
