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

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 21 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Has previously undergone or currently has determined to undergo a primary knee arthroplasty (primary TKA or unicompartmental) or a revision knee that requires the study components or a revision procedure where other treatments or devices have failed. 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 (+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.

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. -

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
