What this trial studies

This observational study aims to assess the performance of Medacta Anatomic Ribbon Surgery (M-ARS) in patients undergoing anterior cruciate ligament (ACL) reconstruction. It will evaluate the survival rate of the M-ARS implants at 6 months post-surgery, along with clinical and functional outcomes, quality of life, and complication rates at 1 month, 1 year, and 2 years post-operatively. Participants will be monitored through a series of follow-up visits, and data will be collected using a web-based tool to ensure accurate tracking of outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with a confirmed ACL rupture requiring surgical reconstruction.

Not a fit: Patients with malignant diseases, infections, functional deficits of the affected limb, or known allergies to surgical materials may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the effectiveness and safety of M-ARS for ACL reconstruction, potentially improving patient outcomes.

How similar studies have performed: While this study focuses on a specific surgical technique, similar observational studies have shown promising results in evaluating surgical outcomes, suggesting potential for success.
