Single-surgeon prospective cohort of 446 metal-on-metal hip resurfacings (384 patients, all under 55 years with primary OA) using cemented femoral and HA-coated uncemented acetabular components, asking whether this technique can outperform conventional THR in a population where THR historically fails early.
When a patient under 55 with end-stage hip OA wants to return to heavy work or impact sport, hip resurfacing with a metal-on-metal bearing is a physiologically compelling alternative to stemmed THR — this series demonstrates that high-demand activity need not be restricted postoperatively, though these early survival results must be weighed against the absence of long-term data and the subsequent recognition of metal ion and ARMD complications in later MoM literature.
