Dynamic intraligamentary stabilization for ACL repair: a systematic review

Area of Science:

• Orthopedic surgery
• Sports medicine
• Biomedical engineering

Background:

• The anterior cruciate ligament (ACL) is crucial for knee stability.
• Dynamic intraligamentary stabilization (DIS) is an emerging technique for ACL repair.
• Understanding the efficacy and limitations of DIS is essential for clinical decision-making.

Purpose of the Study:

• To systematically review and analyze published research on dynamic repair of the ACL.
• To conduct a semi-quantitative analysis of clinical outcomes reported in studies using DIS.

Main Methods:

• Conducted a comprehensive literature search using OVIS and MEDLINE databases.
• Identified and analyzed preclinical and clinical studies focusing on dynamic intraligamentary stabilization (DIS).
• Tabulated results and performed semi-quantitative analysis of the collected data.

Main Results:

• Twenty-three articles on DIS were identified, with most evidence at Level II-IV.
• Reported failure rates for DIS ranged from 4% to 13.6%.
• Higher success rates were observed in proximal ACL ruptures; patient age and activity level influenced failure risk.

Conclusions:

• DIS repair demonstrates potential effectiveness for acute proximal ACL tears.
• Comparative studies evaluating DIS against ACL reconstruction and rigid fixation methods are lacking.
• Further research is needed to establish DIS's role in individualized ACL treatment strategies.
