What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    A total knee arthroplasty will be performed with a bicruciate retaining implant (Journey II, XR). The control group will consist out of patients receiving a posterior stabilized implant (Journey II, BCS).

  • Robot-assisted Total Knee ArthroplastyProcedure or surgery

    A total knee arthroplasty will be performed with robot-assistance (NAVIO).

  • Total Knee Prosthesis - type Posterior StabilizedProcedure or surgery

    A total knee arthroplasty will be performed with a bicruciate retaining implant (Journey II, XR). The control group will consist out of patients receiving a posterior stabilized implant (Journey II, BCS).

What is being measured

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

  1. Patient reported outcome measures

    The following patient reported outcome measures will be evaluated: Knee Injury and Osteoarthritis outcome score. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Measured: Preoperative

  2. Patient reported outcome measures

    The following patient reported outcome measures will be evaluated: Knee Society Score. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Measured: Preoperative

  3. Patient reported outcome measures

    The following patient reported outcome measures will be evaluated: EuroQoL. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Measured: Preoperative

  4. Patient reported outcome measures

    The following patient reported outcome measures will be evaluated: Pain Catastrophizing Scale. The score is a percentage score from 0 to 52, 0 representing no problems and 52 representing extreme problems.

    Measured: Preoperative

  5. Change in patient reported outcome measures

    The change for the following patient reported outcome measures will be evaluated (compared to preoperatively): Forgotten Joint Score. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Measured: Postoperatively at 6 weeks, 6 months, 1 year and 2 years.

  6. Change in patient reported outcome measures

    The change for the following patient reported outcome measures will be evaluated (compared to preoperatively): Knee Injury and Osteoarthritis outcome score. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Measured: Postoperatively at 6 weeks, 6 months, 1 year and 2 years.

  7. Change in patient reported outcome measures

    The change for the following patient reported outcome measures will be evaluated (compared to preoperatively): Knee Society Score. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Measured: Postoperatively at 6 weeks, 6 months, 1 year and 2 years.

  8. Change in patient reported outcome measures

    The change for the following patient reported outcome measures will be evaluated (compared to preoperatively): EuroQoL. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Measured: Postoperatively at 6 weeks, 6 months, 1 year and 2 years.

  9. Change in patient reported outcome measures

    The change for the following patient reported outcome measures will be evaluated (compared to preoperatively): Pain Catastrophizing Scale. The score is a percentage score from 0 to 52, 0 representing no problems and 100 representing extreme problems.

    Measured: Postoperatively at 6 weeks, 6 months, 1 year and 2 years.

Secondary outcomes (4)
  1. Alignment

    Coronal alignment on xrays. The lateral distal femoral angle (LDFA) will be evaluated. This is the angle between the mechanical femoral axis and the line between the distal articular surface of the femur. Additionally the medial proximal tibial angle (MPTA) will be evaluated. This is the line between the condylar surface and the mechanical axis of the tibia on a coronal radiograph.

    Measured: Preoperative and postoperatively at 6 weeks and 6 months.

  2. Knee laxity

    Coronal knee laxity will be evaluated with stress examination. Coronal stress will be evaluated with a stress radiograph. The deviation between the neutral position and position under stress will be measured on a coronal radiograph. The angle between the joint lines will be measured on the coronal radiograph.

    Measured: Preoperative and postoperatively at 1 year.

  3. Knee laxity

    Sagittal knee laxity will be evaluated with stress examination. Sagittal knee laxity will be measured with an AP laxitymeter (GENOUROB; CE Marked). With a standardized setup, anteroposterior laxity can be obtained by measuring the anteroposterior deviation from the neutral position with up to 300N of force.

    Measured: Preoperative and postoperatively at 1 year.

  4. Knee kinematics in 3D after squat, knee flexion/extension, stair ascend and descend.

    Knee kinematics in 3D obtained with fluoroscopy. Patients will be asked to perform squats, a flexion/extension movement, ascend and descend stairs. 3D motion of the prosthesis components can be obtained by projecting the 3D file of the prosthesis components onto the fluoroscopy images.

    Measured: Postoperatively at 1 year.

Questions about this trial

What is this clinical trial studying?

A study testing Total Knee Prosthesis - type Bicruciate retaining, Robot-assisted Total Knee Arthroplasty and Total Knee Prosthesis - type Posterior Stabilized in people with Osteo Arthritis Knee, run by University Hospital, Ghent 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 1 inclusion and 8 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: stopped early, as of the sponsor's last update on 9 Dec 2024. 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?

The study was stopped early (reason given: Patient inclusion difficult.). Results are not available in the source record.

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?

Patient reported outcome measures (time frame: Preoperative). The study lists 9 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 9 Dec 2024.
