Brief Summary

The goal of this post-market study is to confirm the safety, performance and clinical benefits of the Refobacin Revision-3 Bone Cement when used in knee or hip revision surgeries. This will be done by collecting information on:

  • removal of any metal components of the hip or knee implants used in combination with the cement
  • frequency and incidence of adverse events
  • overall pain and functional performance, subject quality of life, and radiographic parameters

Outcome Measures

Primary Outcomes (1)

  • Survivorship

    * removal of any metal components of the hip or knee implants used in combination with the cement * frequency and incidence of adverse events

    3, 5 and 10 years post-operatively

Secondary Outcomes (3)

  • EuroQuol 5D (EQ-5D) Score

    1, 3, 5 and 10 years post-operatively (retrospective, if available, or prospective)

  • Harris Hip Score / Knee Society Score

    1, 3, 5 and 10 years post-operatively (retrospective, if available, or prospective)

  • Radiographic evaluation

    1, 3, 5 and 10 years post-operatively (retrospective, if available, or prospective)

Interventions

Hip or knee revision surgery resulting from aseptic loosening of the prosthesis and/or infection of the prosthesis by gentamicin and/or clindamycin sensitive strains.

Also known as: Revision, Revision surgery

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The population target is all subjects undergoing knee or hip revision surgeries with Refobacin® Revision-3 and a Zimmer Biomet implant approved for revision cases and who meet all of the inclusion and none of the exclusion criteria. Patients requiring a Zimmer Biomet StageOne™ spacer during a two-stage revision will be enrolled for subgroup analysis too.

You may qualify if:

  • Patient is 18 years or older and skeletally mature.
  • Patient is capable of understanding the surgeon's explanations and following his/her instructions, able and willing to participate in the follow-up program.
  • Patient gave consent to take part in the study by signing the Ethics Committee approved Informed Consent Form (ICF).
  • Patient who underwent or will undergo a hip or knee revision surgery with a Zimmer Biomet implant and the Refobacin® Revision-3 Bone Cement.
  • Patient meets at least one of the following indications, as stated in the Instructions for Use (IFU):
  • Patients requires a revision operation resulting from aseptic loosening of the prosthesis and/or infection of the prosthesis by gentamicin and/or clindamycin sensitive strains.
  • Patients undergoing a two-stage revision that requires the fabrication and fixation of short-term total or hemi joint StageOne™ spacers. The device is intended for use in conjunction with systemic antimicrobial therapy (standard approach to an infection).
  • Implantation period of a maximum of 180 days.
  • The molded temporary prosthesis is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers) throughout the implant period.

You may not qualify if:

  • Patient is unwilling or unable to give consent or to comply with the follow-up program.
  • Patient is known to be pregnant or breastfeeding.
  • Patient has any condition that would, in the judgment of the Investigator, place the patient at undue risk or interfere with the study.
  • Patient is a vulnerable subject (prisoner, mentally incompetent or unable to understand what participation to the study entails, a known alcohol or drug abuser, anticipated to be non-compliant).
  • Patient has plans to relocate during the study follow-up period.
  • As stated in the IFU, patient with known hypersensitivity to gentamicin and/or clindamycin and/or to other constituents of the bone cement.
  • The infected Total Hip/Knee Replacement (THR/TKR) devices cannot be removed.
  • A systemic or secondary remote infection is expected or confirmed.
  • Lack of adequate bone structure precludes adequate support of the prosthesis in the proximal femur or acetabular region, or
  • Lack of adequate competence (anatomical and functional) of peripheral ligamentous apparatus and extensor mechanism.
  • The patient is sensitive (allergic) to aminoglycosides.
