Hip arthroplasty with a short cementless stem using a direct anterior approach

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study collects data on patients undergoing primary total hip arthroplasty with a cementless, hydroxyapatite-coated short stem via a direct anterior approach. It will evaluate clinical outcomes, radiographs, and perioperative factors over at least two years of follow-up. The goal is to understand survivorship, radiographic features, and functional results in this younger, more active population. The analysis will help clarify whether the approach and stem design provide favorable outcomes compared with historical experiences. Methods include retrospective and prospective data collection from a single center in Bologna, Italy.
