About this study

Official title: Post-market Observational Study of the ORIGIN® PS Modular Total Knee Prosthesis and Associated Instruments

The study objective is to evaluate safety and performance of the ORIGIN® PS (postero-stabilized) Modular devices and associated instruments, more precisely to evaluate safety by the proportion of patients requiring a revision (i.e. revision rate) at 2-6 months, 1y and 2y post-procedure and to evaluate performance by means of a Knee Society Score (KSS) Score at 2-6 months, 1y and 2y post procedure.

The hypothesis raised for this study, regarding the scoring, is that patients will experience a marked improvement in the natural feel of the prosthesis during the first year after the surgery, and slightly significant improvement at the following interval of 2 years. The overall patient satisfaction is expected to be improved after 2 years follow-up with ORIGIN® PS Modular.

Read the detailed description

The study is ambispective, post market, non-comparative, non-randomized, multicentric and observational in which 200 patients will be enrolled to evaluate the safety and performance of the ORIGIN® PS Modular devices and associated instruments.

Patients will be included in the study during 18 months (inclusion window) and followed-up for 24 months.

  • ORIGIN® PS Modular devicesDevice

    Consecutive eligible subjects have been included which have been treated with the ORIGIN® PS Modular devices.

What is being measured

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

  1. Evaluate safety by the proportion of required revisions

    Proportion of patients requiring a revision at each follow-up visit (surgery, 2-6 months, 1- and 2 years). The revision rate is consistent with the state of the art - Orthopaedic Data Evaluation Panel (ODEP) benchmark system (revision rate not higher than 2.5% to 3.5% at 1 year, 4% to 6% at 5 years and 5% to 7% at 10 years).

    Measured: 2 years post-op procedure

  2. Evaluate performance

    Evaluate performance by means of a Knee Society Score (KSS) and a KSS Function score.

    It aims to reach a KSS Knee score of at least 85,5 / 100 points and a KSS Function score of at least 72,5 / 100 points.

    Measured: 2 years post-op procedure

Secondary outcomes (3)
  1. Evaluate the success of the surgical procedure by means of a surgeon satisfaction questionnaire.

    Surgeon satisfaction: during surgery, the surgeon will assess safety and performance of the associated Instrumentation and implants. The criteria of evaluation of the satisfaction are: Very satisfied - satisfied - unsatisfied - very unsatisfied. Each surgical step is evaluated for each instrument and implant component used by the surgeon. These data will be collected in the case report form based on surgeon satisfaction questionnaire and will be used in clinical evaluation of ORIGIN® PS Modular.

    Measured: Perioperative

  2. Evaluate safety by analyzing the occurencies of adverse events.

    • Evaluate the intraoperative difficulties and complications (the rate should not be higher than 1,8% according to the state of the art).
    • Evaluate post-operative complications during the entire study period.
    • Evaluate the safety of the modular tibial stem by analysing the revision rate for aseptic tibial loosening at each follow-up visit (surgery, 2-6 months, 1 year and 2 years) with a maximum revision rate for aseptic loosening of 5.3% for first intention total knee replacements as cited in the knee joint registries.

    Measured: Perioperative and 2 years post-op procedure

  3. Patient Quality of Life by means of the FJS score

    Assess patients' ability to forget their knee in the short term after surgery, as measured by the "Forgotten Knee Score" (FJS-12: from 0 to 100 points, meaning that "0" is worst case and "100" the best).

    Measured: 2 years post-op procedure

Questions about this trial

What is this clinical trial studying?

An observational study of Total Knee Replacement, run by Symbios Orthopedie SA at 2 sites in France.

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 4 inclusion and 16 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: under way, not looking for participants, as of the sponsor's last update on 4 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. 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?

This study is still under way. Results are not available in the source record yet.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluate safety by the proportion of required revisions (time frame: 2 years post-op procedure). The study lists 2 primary outcomes in all. 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 4 Oct 2024.
