Summary

This study looked back at 134 patients under 75 who had a partial hip replacement after a broken hip. The goal was to see how often the hip socket wears down over time and how often that leads to a second surgery. Researchers also checked if a common way to measure socket erosion is reliable. The study did not test any new treatment.
