Post Market Clinical Follow-Up Study- EVOLUTION® Revision CCK

March 19, 2024 updated by: MicroPort Orthopedics Inc.

Post Market Clinical Follow-Up Study for EVOLUTION® Revision Tibial System and EVOLUTION® Revision Constrained Condylar Knee (CCK) Femur With the EVOLUTION® CCK Tibial Insert

Sponsor is conducting this post market clinical follow-up (PMCF) study to evaluate the safety and efficacy of its EVOLUTION® Revision CCK Tibia and EVOLUTION® Revision CCK Femur with EVOLUTION® CCK Tibial inserts. These type of studies are required by regulatory authorities for all devices that have been approved in Europe (EU) to evaluate the medium and long term clinical evidence. This study has been designed in accordance with MEDDEV2.12/2 rev 2 (European Medical Device Vigilance System) and ISO (International Organization for Standardization) 14155:2011 guidelines.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Enrolling by invitation

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The objectives of this study are:

  1. To estimate the individual component survivorship of EVOLUTION® Revision Tibia, EVOLUTION® Revision CCK Femur, and EVOLUTION® CCK Tibial Insert.
  2. To find out the cumulative incidence of component revision of each component in this combination.
  3. To find out the functional outcome scores at early, midterm, and long-term follow-up.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Primary TKA or Revision

Single study group with either newly or previously implanted patients with EVOLUTION® Revision Tibia and EVOLUTION® Revision CCK Femur with the EVOLUTION® CCK Insert.

Description

Inclusion Criteria:

  1. Has previously undergone or currently has been determined to undergo a revision knee arthroplasty that requires the study (EVOLUTION® Revision Tibial System and EVOLUTION® Revision CCK Femur with the EVOLUTION® CCK Tibial Insert)
  2. Decision to perform the study index surgery with the required study components (EVOLUTION® Revision Tibial System and EVOLUTION® Revision CCK Femur with the EVOLUTION® CCK Tibial Insert) is pre-determined regardless of the research.
  3. Previously implanted subjects must be enrolled within 3 years (+6 months) of their study index surgery
  4. Willing and able to complete required study visits and assessments through the 10 year post-operative follow-up visit.

Bilateral subjects can have both TKAs enrolled in the study provided:

  1. the specified combination of components (EVOLUTION® Revision Tibial System and EVOLUTION® Revision CCK Femur with the EVOLUTION® CCK Tibial Insert) were implanted in both
  2. all other aspects of the Inclusion/Exclusion Criteria are satisfied
  3. enrollment does not exceed the subject count specified
  4. the subject agrees to a second Informed Consent document and data collection specific to the second TKA.

Exclusion Criteria:

  1. Skeletally immature (less than 21 years of age) at time of implantation.
  2. Has an overt infection at the time of implantation.
  3. Has inadequate neuromuscular status (e.g., prior paralysis, fusion, and/or inadequate abductor strength), poor bone stock, poor skin coverage around the joint which would make the procedure unjustifiable.
  4. Currently enrolled in another clinical investigation which would affect the endpoints of this protocol.
  5. Has documented substance abuse issues.
  6. Has an emotional or neurological condition that would pre-empt their ability or willingness to participate in the study.
  7. Currently incarcerated or has impending incarceration.
  8. Has a medical condition, as judged by the Investigator, that would interfere with the subject's ability to comply with the requirements of the protocol.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Individual component survivorship
Time Frame: 10 years post-operative
Individual component survivorship for tibial base, femoral, and tibial insert at specified intervals out to 10 years follow-up.
10 years post-operative

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patient Reported Outcomes- Questionnaires
Time Frame: 10 years post-operative
  • functional scores for subjects, as assessed by Knee Injury and Osteoarthritis Outcome Score (KOOS), out to 10 years follow-up
  • functional scores for subjects, as assessed by EuroQol-5D-5L (EQ-5D-5L) Scores, out to 10 years follow-up
  • subject satisfaction measures with their Total Knee Arthroplasty (TKA) procedure using the Forgotten Joint Score
  • subject satisfaction measures with their TKA procedure using the Satisfaction Survey
10 years post-operative
Incidence of component revision
Time Frame: 10 years post-operative
the cumulative incidence of component revision at specified intervals will be determined out to 10 years follow-up
10 years post-operative
Radiolucencies
Time Frame: 10 years post-operative
the presence, zone, and the size of radiolucencies surrounding implanted components will be determined
10 years post-operative
Adverse Events and Adverse Device Effects
Time Frame: 10 years post-operative
characterization of adverse events and adverse device effects

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
