Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single-center retrospective observational cohort study of consecutively operated patients who underwent primary total hip arthroplasty with a SYMBOL CUP DM HA hemispherical dual mobility acetabular implant. The purpose of this study is to estimate the safety and efficacy of that implant at two-year follow-up.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Description according to PICOS framework:

Patients:

\- Adult men and women requiring a primary total hip arthroplasty

Intervention:

\- Primary THA with SYMBOL CUP DM HA hemispherical dual mobility acetabular implant.

Comparator: None

Outcomes:

* Safety 1: Implant survival over 2-year follow-up.
* Safety 2: All adverse events, with focus on implant dislocation, infections, revision surgery
* Efficacy 1: Harris Hip Score (HHS) at baseline and 1-year follow-up.
* Efficacy 2: Modified HHS consisting of pain + functional subscores at baseline, 1-year and 2-year follow-ups.
* Efficacy 2: Devane score at baseline, 1-year and 2-year follow-ups.
* Efficacy 3: Charnley classification at baseline, 1-year and 2-year follow-ups.
