About this study

Analysis of Radiological Features of Lateral Femoral Impaction Fracture (LFC-IF) / Lateral Femoral Notch Sign will be performed on MRIs of consecutive patients after anterior cruciate ligament (ACL) injuries and without ACL injuries.

Read the detailed description

Two independent measurers will twicely measure the radiological features of Lateral Femoral Impaction Fracture / Lateral Femoral Notch Sign on MRIs of consecutive patients after anterior cruciate ligament (ACL) injuries and without ACL injuries. In cases without ACL injuries, radiological features of terminal sulcus (TS), a native sulcus located on the lateral femoral condyle, will be measured. Intra- and inter-rater agreements will be calculated.

The following radiological features will be assessed/ measured:

  1. Presence of LFC-IF/ TS
  2. LFC-IF/ TS depth
  3. LFC-IF/ TS length
  4. Distance from Blumensaat line to the front border of LFC-IF / TS
  5. Distance from Blumensaat line to the deepest part of LFC-IF / TS
  6. Distance from Blumensaat line to the rear border of LFC-IF / TS

What participants receive

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

  • Measurements on knee MRI performed during routine clinical practiceDiagnostic test

    Patients after knee injury are often advised to undergo knee MRI for diagnosis. Measurements on knee MRI performed during routine clinical practice will be made.

Questions about this trial

What is this clinical trial studying?

An observational study of Anterior Cruciate Ligament Injuries and Anterior Cruciate Ligament Rupture, run by Artromedical Konrad Malinowski Clinic at 1 site in Poland.

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 2 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: status not confirmed, as of the sponsor's last update on 12 Jan 2023. 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 Poland. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Konrad Malinowski, MD PhD (+48 509812212, malwin8@wp.pl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Distance from Blumensaat line to the rear border of LFC-IF / TS (time frame: At the time of MRI exam). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05682820, which also lists 5 linked publications.

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 12 Jan 2023.
