Periprosthetic joint infection after hemiarthroplasty for hip fracture is a distinct clinical entity associated with high mortality

HHA-PJI is an uncommon complication, but is significantly associated with mortality. All currently identified predictors are nonmodifiable.

HHA-PJI is a different disease compared to elective PJI with distinct epidemiology, pathogens, risk factors, and outcomes, which require targeted research specific to this unique population.
