Researchers from UK, in collaboration with Daniel Prieto-Alhambra from the musculoskeletal research group of IMIM (Hospital del Mar Medical Research Institute) and Jordi Gol from the IDIAP have studied the mortality rate after 10 years of more than 400,000 patients with osteoarthritis who had undergone surgery for hip replacement. They found that those who had been operated by a resurfacing hip prosthesis had almost 50% less 10-year mortality than those who had undergone a total hip replacement. The study has been published in the prestigious British Medical Journal.
"This finding is surprising and opens a new paradigm that could condition the indication of the type of intervention. Now we have to carry out further studies and clinical trials to confirm the causality of this effect and to define all aspects that affect this different mortality "explains Daniel Prieto-Alhambra.
