NCT04322799

Brief Summary

A prospective randomized study comparing two types of cemented acetabular components, a highly-crosslinked polyethylene or conventional polyethylene in total hip arthroplasty. Primary outcome are component wear measured by RSA, secondary outcomes are migration and complications. Patients are evaluated 5 years postoperatively.

Outcome Measures

Primary Outcomes (1)

  • Magnitude of Polyethylene Wear

    The size of the femoral component penetration into the polyethylene measured in millimeters per year and the volumetric annual wear millimetres with radiostereometric (RSA) analysis of radiographs.

    0-5 years

Secondary Outcomes (2)

  • Magnitude of Cup Migration

    0-5 years

  • Surgical complications

    0-5 years

Study Arms (2)

Acetabular cup HXLPE (Intervention)

EXPERIMENTAL

Randomization to HXLPE acetabular component.

Procedure: Device: Randomization between prosthetic components

Acetabular cup Conventional PE (control)

EXPERIMENTAL

Randomization to Coventional PE as control group

Procedure: Device: Randomization between prosthetic components

Interventions

Patients are randomized between two types of cup components in total hip arthroplasty. Identical cups made of either highly-crosslinked polyethylene or conventional polyethylene.
