Evaluating knee laxity during ACL and meniscus surgeries

Intraoperative Laxity Evaluation of Anterior Cruciate Ligament Reconstruction, Anterior Cruciate Ligament Revision and Meniscus Transplantation

Istituto Ortopedico Rizzoli · NCT03441165

This study tests how loose the knee is in people having surgery for ACL injuries or meniscus problems to see how well the surgeries work.

What this trial studies

This study evaluates knee laxity in patients undergoing anterior cruciate ligament (ACL) reconstruction, ACL revision, or meniscus transplantation. Participants will have their knee's kinematic data assessed both before and after the surgical procedure using advanced systems. The study focuses on comparing the static and dynamic laxity of the knee joint to determine the effectiveness of the surgical interventions. All necessary data will be collected during the operation, eliminating the need for follow-up assessments.

Who should consider this trial

Good fit: Ideal candidates are patients aged 14 to 65 who are scheduled for ACL reconstruction, ACL revision, or meniscus transplantation.

Not a fit: Patients who are unable to understand the study or have not provided informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance surgical techniques and improve outcomes for patients undergoing ACL and meniscus surgeries.

How similar studies have performed: While there have been studies on knee laxity, this specific approach using intraoperative kinematic evaluation is relatively novel.
