Patients with a history of childhood hip disease undergoing total hip arthroplasty may have a lower risk of mortality compared to the general population, according to results presented at the Virtual EFORT Congress.

Miriam Wadström and colleagues matched 4,043 patients undergoing unilateral or bilateral THA due to secondary osteoarthritis due to pediatric hip disease with 19,388 matched controls from the general population based on age, gender, and place of residence.

“Socioeconomic data was extracted from Statistics Sweden and causes of death were extracted from a Swedish mortality database,” Wadström said in her presentation.

At the time of the first surgery, Wadström noted that most patients were under the age of 50, followed by patients aged 50 to 59. She added that most of the patients were female and most had hip dysplasia as the diagnosis.

“We can see that patients exposed to THA as a result of childhood hip disease had lower income, lower educational attainment and higher rates of comorbidity compared to the unexposed individuals,” Wadström said. “However, the majority of patients had a low level of comorbidity overall and had at least a high school diploma.”

Overall, a small number of patients died within 90 days of surgery, Wadström said. Although the risk ratios showed a 90-day reduced mortality risk in patients undergoing THA, Wadström noted that the result was not statistically significant.

“When we looked at the overall mortality risk, we found a reduced risk of mortality for the exposed individual compared to the unexposed group,” Wadström said.
