Introduction Studies evaluating the association of dementia in patients undergoing total hip arthroplasty (THA) for femoral neck fractures are limited. The aim was to investigate whether patients who have dementia undergoing THA for femoral neck fractures have higher rates of (1) in-hospital lengths of stay (LOS); 2) complications (medical and prostheses-related); and 3) healthcare expenditures. Methods A retrospective query using the PearlDiver database from January 1st, 2005 to March 31st, 2014 to identify patients with dementia undergoing primary total hip arthroplasty for the treatment of femoral neck fractures was performed. Dementia patients were 1:5 ratio matched to controls which yielded 22,758 patients in the study with ( n  = 3,798) and without ( n  = 18,960) dementia. Primary outcomes included comparing LOS, complications, and costs. A logistic regression was constructed to calculate the odds-ratios (OR) of dementia on complications. A p -value less than 0.004 was significant. Results Dementia patients had longer LOS (7-days vs. 6-days, p
