A recent registry-based study from the Norwegian Arthroplasty Register found an increased mortality risk for cemented fixation on the first 24h after surgery \cite{Kristensen_2020}, a previous study using the same registry found that this risk was more pronounced in the group of patients with more comorbidities\cite{Talsnes_2013}. This is in contrast with the findings of another study on the same dataset that defends that perioperative deaths were associated with advanced age and comorbidities, not with the type of fixation \cite{Dale_2019}.
