NCT04833634

Brief Summary

The main objective of this study is to represent the treatment reality at the study site and to draw conclusions from cases of failure or suboptimal outcome. Potential risk factors for revision surgery, suboptimal outcome or radiologic sign of loosening, bone non-union or stem subsidence will be evaluated. Next to the functional outcome, stem subsidence will be used as an important indicator for a stable fixation of the revision stem.

Outcome Measures

Primary Outcomes (1)

  • Hip stem survival measured by Kaplan-Meier

    The primary endpoint of the study is hip stem survival, which is a common indicator for implant performance, which can also be used for comparison with implant registry data.

    One scheduled Follow-Up visit per patient, 2-7 years after initial implantation

Secondary Outcomes (8)

  • Functional Outcome: Oxford Hip Score

    One scheduled Follow-Up visit per patient, 2-7 years after initial implantation

  • Patient satisfaction with their endoprosthetic revision treatment

    One scheduled Follow-Up visit per patient, 2-7 years after initial implantation

  • Radiological evaluation (standard x-rays): Bone healing

    One scheduled Follow-Up visit per patient, 2-7 years after initial implantation

  • Radiological evaluation (standard x-rays): osseointegration

    One scheduled Follow-Up visit per patient, 2-7 years after initial implantation

  • Radiological evaluation (standard x-rays): radiographic loosening

    One scheduled Follow-Up visit per patient, 2-7 years after initial implantation

  • +3 more secondary outcomes

Other Outcomes (1)

  • Descriptive Analysis of Patient characteristics

    One scheduled Follow-Up visit per patient, 2-7 years after initial implantation
