We assessed important patient risk factors for postoperative periprosthetic fractures after revision total hip arthroplasty (THA) using prospectively collected Institutional Joint Registry data. We used univariate and multivariable-adjusted Cox regression analyses. There were 330 postoperative periprosthetic fractures after 6281 revision THAs. In multivariable-adjusted analyses, hazard ratio (95% confidence interval) of periprosthetic fracture was higher for women (1.66 [1.32-2.080], P < .001), a higher Deyo-Charlson comorbidity index of 2 (1.46 [1.03-2.07]) and index of 3+ (2.01 [1.48-2.73]; overall, P < .001), and operative diagnosis, especially previous nonunion (5.76 [2.55-13.02]; overall, P < .001). Hazard ratio was lower in patients 61 to 70 years old (0.64 [0.49-0.84]) and 71 to 80 years old (0.57 [0.43-0.76]) compared with those younger than 60 years (overall, P < .0001). Our study identified important modifiable and unmodifiable risk factors for fractures after revision THA.
