Study groupRoleWhat they receive
VitelenePlasmacup DC® with Vitelene® inlay manufactured by UHMWPE-XE (Ultra High Molecular Weight Polyethylene highly cross-linked with 0.1% Vitamin E) in combination with one of four different Aesculap® stems (Bicontact®, TRJ®, Metha®, Excia®)
Receives: Device: Vitelene
XLPEPlasmacup DC® with a standard polyethylene inlay manufactured by UHMWPE-X (Ultra High Molecular Weight Polyethylene highly cross-linked) in combination with one of four different Aesculap® stems (Bicontact®, TRJ®, Metha®, Excia®)
Receives: Device: XLPE

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Analysis and measurement of oxidation index of the Polyethylene Inlay after Revision

    The Oxidation index is measured after explantation in case of loosening of the inlay

    Measured: Oxidation index is assessed in case of loosening and revision within 15 years

Secondary outcomes (3)
  1. Manifest radiological osteolyses

    Measured: Measured radiologically after 1, 5, 10 and 15 years

  2. Traceable wear of polyethylene over 0.5 mm

    Measured: Measured radiologically after 1, 5, 10 and 15 years

  3. Clinical Outcome

    Clinical Outcome measured by Harris Hip Score (HHS), Hip disability and osteoarthritis outcome score(HOOS), University of California at Los Angeles Score (UCLA)

    Measured: After 1, 5, 10 and 15 years
