Results of advanced core decompression in patients with osteonecrosis of the femoral head depending on age and sex—a prospective cohort study

Abstract

The study shows that the number of therapy failures is significantly higher in older patients, with 40 years of age marking the borderline. Patients' sex does not seem to affect the outcome of treatment, and postoperative clinical scores appear to be identical with individuals not affected by therapy failure. Since age and sex are unalterable parameters, the study helps to provide valuable predictions regarding the chances of long-term hip survival after treatment of osteonecrosis.
