About this study

Official title: A Multi-Centre Clinical Investigation To Evaluate The Safety And Performance Of The Freedom Total Knee® System With The PEEK-OPTIMA Femoral Component

Prospective, multi-centre, non-comparative, post-market surveillance clinical study

Read the detailed description

PRIMARY ENDPOINT:

  • The primary endpoint is to evaluate the procedural success ie successful implantation of the device in the opinion of the surgeon

SECONDARY ENDPOINTS:

The secondary endpoints are to evaluate:

  • KSS Knee scores and KSS Function scores at 6 weeks, 6, 12 and 24 months post-treatment compared to pre-treatment
  • Subject reported outcomes (SF-36, Oxford Knee Score and WOMAC) at 6 weeks, 6, 12 and 24 months post-treatment compared to pre-treatment
  • Stability of the device through radiographic analysis to assess alignment and component position at immediate post-treatment, 6 weeks, 6, 12 and 24 months post-treatment
  • Safety in terms of adverse events and device deficiencies throughout the clinical investigation including any additional knee treatments and/or surgery
  • Survivorship analysis of the device at 12 and 24 months and annually thereafter

What is being measured

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

  1. Knee Society Score (KSS)

    Pre-and post-operative function and patient and mechanical assessment. The KSS contains questions in 2 sections: knee joint (pain, range of motion, stability) and function (walking distance, ability to climb stairs). The greater score correlates to better outcome.

    Measured: Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

Secondary outcomes (4)
  1. Visual Analog Scale (VAS)

    Patient self administered overall satisfaction (scale from 1 worse -10 best)

    Measured: Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

  2. SF-36

    Assessment domains to explain variations in patient outcomes. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.

    Measured: Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

  3. Western Ontario and McMaster Universities Arthritis Index (WOMAC)

    Assessment of OA of the knee or hip. Possible score range of 0- 20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function

    Measured: Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

  4. Radiographic assessment

    Subjective review and assessment of serial radiographs. Items include presence or absence of radiographic evidence of component loosening, malposition, migration and periprosthetic osteolysis, bone loss or interface composite (bone-cement-component) breakdown.

    Measured: Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months

Questions about this trial

What is this clinical trial studying?

A study testing PEEK-Optima Femoral Component in people with Osteoarthritis, Knee and Rheumatoid Arthritis of Knee, run by Maxx Orthopedics Inc at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 15 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Robert Eberle (+1 (919) 280-6900, robert.eberle@maxxortho.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Knee Society Score (KSS) (time frame: Change from Pre-op versus 6 weeks, 3 months, 6 months,12 months and 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jul 2021.
