AI learns to spot clean surgical zones in ACL repair
NCT ID NCT07636278
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.

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.
