Mortality rate after total knee arthroplasty or total hip arthroplasty in patients with a history of liver transplant

In this editorial I comment on the article by Ahmed et al published in a recent issue of the World J Orthop 2023; 14: 784-790. It is well known that patients who have undergone a liver transplant (LT) may need to have a total hip arthroplasty (THA) or total knee arthroplasty (TKA) implanted. Ahmed et al stated that the mortality rate in these patients was similar to the one of the general population. However, there are three articles previously published that found higher mortality in LT patients who experienced THA/TKA than in the general population (individuals without LT). Therefore, in this Editorial I would like to point out that there is controversy in the literature regarding whether LT patients undergoing THA/TKA have higher mortality than the general population. Therefore, future research should attempt to resolve this controversy.
