  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patient is diagnosed with osteoarthritis and requiring primary knee arthroplasty
  • All consecutive patients ("usual care") are included to prevent selection bias in the migration analysis.
  • Patient is capable of giving informed consent and expressing a willingness to comply with this study

Who cannot join

  • Status after patellectomy
  • In case flexion is less than 90 degrees
  • The patient is unable or unwilling to sign the Informed Consent specific to this study
  • The patient does not understand the Dutch or English language good enough to participate
  • Patients indicated for revision arthroplasty
  • Patient is diagnosed with rheumatoid arthritis
  • When there are not enough markers visible in the baseline RSA photograph and it will not improve by placing the patient in another position, the patient will be excluded from the study (secondary exclusion criteria).

About this study

Official title: A CLINICAL RANDOMIZED CONTROLLED RSA TRIAL COMPARING THE CEMENTLESS ATTUNE ROTATING PLATFORM KNEE SYSTEM TO THE CEMENTLESS LCS ROTATING PLATFORM KNEE SYSTEM

The LCS Complete Cementless Knee by DePuy Synthes is a rotating platform knee replacement with a good clinical track record and good survival rates.

The cementless ATTUNE Cruciate Sacrificing (CS) Rotating Platform Knee by DePuy Synthes has been designed to provide better range of motion and address the unstable feeling some patients experience during everyday activities, such as stair descent and bending. It is expected that the cementless ATTUNE Rotating Platform Knee will have regulatory approval early 2016. Patient inclusion will start after regular approval has been obtained.

The objective of this study is to accurately assess and compare migration, clinical and radiological outcome and patient reported outcomes (PROMS) of two TKR prostheses: the Cementless ATTUNE Rotating Platform Cruciate Sacrificing Knee System and the LCS Complete Cementless Cruciate Sacrificing Knee System (rotating platform design), both by DePuy Synthes, Warsaw, Indiana, USA. In this single-blind, randomized non-inferiority trial, 32 patients with the ATTUNE Knee System and 32 patients with LCS Knee System will be included.

The study population will consist of patients with symptomatic osteoarthritis of the knee scheduled for TKR surgery at the Department of Orthopaedics, Spaarne Gasthuis, Hoofddorp, The Netherlands. Annually 300 TKA procedures are performed in this department, of which about 95% is Osteo Arthritis (OA). The investigator anticipates that inclusion can be accomplished within a 1 year period and that the total study duration is 3 years.

Main study parameters/endpoints are:

  • Migration, measured by means of RSA.
  • Patient Reported Outcome Measures by means of questionnaires.

What is being measured

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

  1. Migration, measured by means of RSA

    Migration (MTPM in mm) of the prosthesis with respect to the host bone measured by means of roentgen stereophotogrammetric analysis (RSA).

    Measured: 2 Years

Secondary outcomes (4)
  1. EQ-5D

    General Health: EuroQol 5 Dimensional (EQ-5D) Health Questionnaire measured using patient questionnaire

    Measured: 2 Years

  2. KOOS

    Knee Function: Knee injury and Osteoarthritis Outcome Score (KOOS) measured using patient questionnaire

    Measured: 2 Years

  3. VAS pain

    Pain score after activity and during rest; (Likert scale 0-10)

    Measured: 2 Years

  4. 2 Anchor questions

    Two anchor questions (Likert scale 1-7) about change in functioning and pain since surgery.

    Measured: 2 Years

Questions about this trial

What is this clinical trial studying?

A study testing ATTUNE Knee Prosthesis by DePuy and LCS Knee Prosthesis by DePuy in people with Osteoarthritis Arthritis and Joint Disease, run by Spaarne Gasthuis at 2 sites in Netherlands.

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 3 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: finished, as of the sponsor's last update on 27 Apr 2022. 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 Netherlands. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Migration, measured by means of RSA (time frame: 2 Years). 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 27 Apr 2022.
