M-ARS ACL Post-marketing Surveillance Study

This s a prospective, multicenter, non-controlled, observational study to evaluate the outcomes of Medacta Anatomic Ribbon Surgery (M-ARS) in the reconstruction of the anterior cruciate ligament (ACL).

Participants will be informed about the study, both orally and in writing, during a preoperative visit. The investigator will answer any questions that may arise and will collect the informed consent. During the study, enrolled participants will be able to withdraw at any time and for any reason.

The study is conducted according to the following schedule:

• V1 : Inclusion during a preoperative visit
• V2: Surgery
• V3: Follow-up visit at 1 month ± 15 days post-surgery
• V4: Follow-up visit at 6 months ± 30 days post-surgery
• V5: Follow-up visit at 12 months ± 60 days post-surgery
• V6: Follow-up visit at 24 months ± 90 days post-surgery

The following data will be collected:

• Survival rate of implants evaluating the incidence of implants failure, where implant failure is defined as revision, loosening, or any definite change in the position of components (V3-V6).
• Clinical and functional outcomes, measured with the International Knee Documentation Committee (IKDC) score (V1, V3-V6)
• Quality of Life, measured with the EQ-5D score (V1, V3-V6)
• Occurrence of intraoperative and postoperative complications (V2-V6)

Depending on standard practice, imaging assessment of implants and bone tunnels may be performed.

A web-based data collection tool will be used as Electronic Data Capture (EDC). All the information required by the protocol will be collected in electronic case report forms (eCRF).

The statistical analysis will be performed according to a pre-established statistical analysis plan. Missing values will not be replaced by estimated values but will be considered as missing in the statistical analysis.
