[Post-surgical hip complications in patients with and without a history of COVID-19]

The World Health Organization (WHO) declared COVID-19 a pandemic on March 11, 2020. Patients who tested positive for COVID-19 experienced a higher overall rate of post-surgical complications and hospital mortality.

To compare the asociation of post-surgical complications presented in post-surgical hip patients with and without history of COVID-19 infection.

Prospective cohort study. The inclusion criteria were: post-hip surgery adults with and without a history of COVID-19 infection who attended their post-surgical follow-up consultation. The association of post-surgical complications in both groups was studied. The association of complications was analyzed with the chi-squared statistical test, and the effect size with Cramer's V test.

The association of complications and a history of COVID-19 infection was moderate, with a chi-squared of 2.55, V Cramer of 0.23. The most frequent complication was aseptic loosening of prosthetic components. The pre-surgical diagnosis and its association with both groups had a chi-squared of 10.07, and a V Cramer of 0.45, at the expense of hip fracture.

A history of COVID-19 infection may be associated with the presence of post-surgical complications. Aseptic loosening of prosthetic components was the most frequent complication in both groups of patients, and hip fracture was the main pre-surgical diagnosis.
