AI learns to spot clean surgical zones in ACL repair

NCT ID NCT07636278

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This observational study tests whether artificial intelligence can automatically recognize clean surgical areas and key bone landmarks on video from routine ACL knee reconstruction. About 100 adults undergoing ACL surgery will have standard arthroscopic video recorded and used to train and validate the AI software. No extra procedures or time are needed. The goal is to see if AI can help guide tunnel placement, but this is an early, non-treatment study.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this AI could help surgeons place bone tunnels more accurately during ACL reconstruction, potentially improving surgical outcomes.
What could go wrong
This is an early observational study with no direct treatment benefit. The AI may not work reliably in all patients or surgical settings.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Patients referred to and treated at the Knee Surgery and Sports Traumatology Unit of IRCCS Galeazzi-Sant'Ambrogio in Milan, Italy. The institution is a tertiary orthopaedic referral hospital and a recognised Italian Scientific Hospital for Research and Care (Istituto di Ricovero e Cura a Carattere Scientifico), dedicated to the musculoskeletal system and performing a very high yearly volume of orthopaedic procedures. Within the institution, the Knee Surgery and Sports Traumatology Unit is a homogeneous surgical team with a substantial annual caseload of arthroscopic anterior cruciate ligament reconstructions. Enrolment is single-centre, prospective and consecutive across the study period.

Inclusion Criteria: * Age 18 years or older * Scheduled for primary arthroscopic anterior cruciate ligament reconstruction at IRCCS Galeazzi-Sant'Ambrogio * Signed written informed consent Exclusion Criteria: * Revision anterior cruciate ligament reconstruction * Arthroscopic video quality judged inadequate by the investigator (artefacts, insufficient illumination, uninterpretable images) * Failure to sign informed consent, or withdrawal of consent
