Trial summary

Incident rates of ACL rupture are greatest in 16-39 year olds at almost 1 in 1,000. Performance Based Investigations (PBIs) can be used to evaluate and select correct approaches to patient treatment, and biochemical, biomechanical and physiological biomarkers in other conditions are sensitive in distinguishing between… Read more about this study

About this study

Official title: A Pilot Study to Investigate Biomarkers in ACL Patients and Healthy Controls

Incident rates of ACL rupture are greatest in 16-39 year olds at almost 1 in 1,000.

Performance Based Investigations (PBIs) can be used to evaluate and select correct approaches to patient treatment, and biochemical, biomechanical and physiological biomarkers in other conditions are sensitive in distinguishing between disease state severities, type of injuries and responsiveness to treatment. Despite the measurement sensitivity of PBIs, these are not widely used possibly owing to their focus postoperatively where benefits are less worthwhile.

This study aims to investigate novel biomarkers as performance based investigations (PBIs) to improve surgical and treatment strategies in anterior cruciate ligament (ACL) patients. The objectives are to identify whether biomarkers, collected before and after operations, can: 1) Assist the surgeon in decision making; 2) Lead to improved prognosis; 3) Be used to predict the outcomes of prognosis, and; 4) Correlate with disease signs/ smoking to help further understand ACL injuries.

What is being measured

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

  1. The change in knee varus/valgus from baseline to 6 weeks post-ACL reconstruction, measured when performing a single leg squat.

    Measured: Baseline, 6 weeks

  2. The change in knee varus/valgus from baseline to 6 months post-ACL reconstruction, measured when performing a single leg squat

    Measured: Baseline, 6 months

  3. The change in peak vertical ground reaction force from baseline to 6 weeks post-ACL reconstruction, measured when performing a novel isometric task during sitting.

    Measured: Baseline, 6 weeks

  4. The change in peak vertical ground reaction force from baseline to 6 months post-ACL reconstruction, measured when performing a novel isometric task during sitting.

    Measured: Baseline, 6 months

  5. The change in anterior-posterior centre of pressure displacement from baseline to 6 weeks post-ACL reconstruction, measured when performing a 10 second standing balance task.

    Measured: Baseline, 6 weeks

  6. The change in anterior-posterior centre of pressure displacement from baseline to 6 months post-ACL reconstruction, measured when performing a 10 second standing balance task.

    Measured: Baseline, 6 months

  7. The change in time taken to complete a sit-to-stand task, from baseline to 6 weeks post-ACL reconstruction

    Measured: Baseline, 6 weeks

  8. The change in time taken to complete a sit-to-stand task, from baseline to 6 months post-ACL reconstruction

    Measured: Baseline, 6 months

Secondary outcomes (5)
  1. The change in Interleukin-6 obtained from blood samples at baseline to 6 months post-ACL reconstruction

    Measured: 6 months post-ACL reconstruction

  2. The change in Tegner Activity Score from baseline to 6 months post-ACL reconstruction

    Measured: 6 months post-ACL reconstruction

  3. The change in Lysholm Knee Scoring Scale from baseline to 6 months post-ACL reconstruction

    Measured: 6 months post-ACL reconstruction

  4. The change in International Knee Documentation Committee subjective knee evaluation form from baseline to 6 months post-ACL reconstruction

    Measured: baseline to 6 months post-ACL reconstruction

  5. The difference in bone morphogenetic protein-7 (BMP-7) between smokers and non-smokers who undergo ACL reconstruction

    Measured: At time of surgery

Questions about this trial

What is this clinical trial studying?

A study testing Surgeons knowledge of pre-operative PBIs in people with Rupture of Anterior Cruciate Ligament, run by United Lincolnshire Hospitals NHS Trust at 1 site in United Kingdom.

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 2 inclusion and 4 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 May 2022. 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 United Kingdom. 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?

The change in knee varus/valgus from baseline to 6 weeks post-ACL reconstruction, measured when performing a single leg squat. (time frame: Baseline, 6 weeks). The study lists 8 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 27 May 2022.
