Artiqo_RSA: Migration of the cemented A2® Type B prosthesis: a radio stereometric analysis

The migration of prosthesis components (stems) will be evaluated in patients receiving a total hip arthroplasty. The purpose of this study is to evaluate the migration behaviour of the cemented A2® Type B stem (Artiqo, Lüdinghausen, Germany) using radiostereometric analysis (RSA). The objective is to determine whether the A2 stem demonstrates non-inferior fixation stability compared to established thresholds for cemented shape-closed designs. In addition, complications, adverse events, and PROMs will be documented.
