Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

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

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

N/A

Sampling Method

Non-Probability Sample

Study Population

All participants will be selected by their respective surgeons. Participants will be screened by eligible surgeon staff and will have the required implant for each site.

Description

Inclusion Criteria:

  1. Patients in the age range of 18 years to 85 years (both inclusive)
  2. Patients who have a BMI less than 35
  3. Patients who do not have previous surgery on the implanted knee that might restrict their movement
  4. Patient who are at least 6 months post-operative
  5. Patients who do not experience any pain or other post-operative complications
  6. Patients who have a stable TKA and can perform a deep knee bend activity
  7. Patients who are willing to participate in this study and are willing to sign appropriate HIPAA and informed consent forms
  8. Subjects will have a Journey II knee system

Exclusion Criteria:

  1. Pregnant, potentially pregnant, or lactating females. To satisfy radiation protocol, each female subject will be asked if she is pregnant, or possibly could be pregnant. A pregnant person will not be allowed to participate in the study.
  2. Patients who have currently enrolled in a fluoroscopic study within the past year.
  3. Patients currently involved in any personal injury litigation, medical/legal or workman's compensation claims.
  4. Patients with known drug or alcohol abuse histories or psychological disorders that could affect ability to complete all aspects of the study.
  5. Patients with neurological or musculoskeletal disorders that might adversely affect weight-bearing motion ability
  6. Subjects who are unable to perform a deep knee bend.
  7. Subjects who are unwilling to sign Informed Consent/ HIPAA documents.
  8. Subjects without the required type of knee implant.

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
Femorotibial Medial Condylar Rollback
Time Frame: Baseline, at time of observation
The condylar rollback of the medial condyle will be observed at a single instance in time. Higher rollback indicates more motion and improved kinematics. Participants will have previously undergone a total knee arthroplasty but data cannot be collected on their preoperative kinematics. Outcome will be measured in [mm].
Baseline, at time of observation
Femorotibial Lateral Condylar Rollback
Time Frame: Baseline, at time of observation
The condylar rollback of the lateral condyle will be observed at a single instance in time. Higher rollback indicates more motion and improved kinematics. Participants will have previously undergone a total knee arthroplasty but data cannot be collected on their preoperative kinematics. Outcome will be measured in [mm].
Baseline, at time of observation
Femorotibial Axial Rotation
Time Frame: Baseline, at time of observation
The femorotibial axial rotation will be observed at a single instance in time. Higher rotation indicates more motion and improved kinematics. Participants will have previously undergone a total knee arthroplasty but data cannot be collected on their preoperative kinematics. Outcome will be measured in [deg].
Baseline, at time of observation
Femorotibial Weight Bearing Flexion
Time Frame: Baseline, at time of observation
The femorotibial weight bearing flexion will be observed at a single instance in time. Higher flexion indicates greater range of motion and improved kinematics. Participants will have previously undergone a total knee arthroplasty but data cannot be collected on their preoperative kinematics. Outcome will be measured in [deg].
Baseline, at time of observation

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 15, 2021

Primary Completion (Actual)

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
