Prosthetic joint infection following hip fracture and degenerative hip disorder: a cohort study of three thousand, eight hundred and seven consecutive hip arthroplasties with a minimum follow-up of five years.

Purpose Prosthetic joint infections (PJIs) occur on a regular basis and with an increasing incidence. Under reporting of complications to national registries and unreliable ICD-10 coding increases the risk of under estimating the true rate of PJIs after hip arthroplasty. Also, the microbiology and final outcome is less well described, especially for hip-fracture patients operated upon with primary and secondary fracture prostheses. Our aim was to analyse re-operation rate, outcome and microbiology of PJIs following hip arthroplasty in patients operated upon due to hip fractures and degenerative hip disorders.
