Examining Techniques for Treatment of Medial Meniscal Ramp Lesions During Anterior Cruciate Ligament Reconstruction: A Systematic Review

      Abstract

      Purpose

      The purpose of this study was to systematically review the clinical outcomes and adverse events among different techniques for treatment of medial meniscal ramp lesions performed in conjunction with anterior cruciate ligament (ACL) reconstruction.

      Methods

      A systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Cochrane Reviews, Web of Science, and Medline databases were searched for studies examining clinical outcomes after surgical treatment of ramp lesions. Studies were selected if they met the following criteria: (1) evaluation of the outcome of surgical repair of meniscal ramp lesions, (2) injuries associated with ACL tears, (3) minimum 6-month follow up, (4) publication in a peer-reviewed journal, and (5) English language or translation readily available.

      Results

      Seven studies met inclusion criteria (485 patients; mean age 27.1 years [range 12 to 59]; mean follow-up 26.9 months [range 8 to 40]). Two all-inside techniques (suture-hook and an all-inside meniscus repair device) in addition to abrasion and trephination alone were analyzed. Each technique demonstrated significant increases in postoperative Lysholm and International Knee Documentation Committee (IKDC) scores, reaching the established minimal clinically important difference (MCID) for each patient reported outcome. Incomplete healing was documented in 12.1% to 12.9% of cases in which the tear was not repaired at the time of ACL reconstruction, 2.3% to 11.7% in cases using the suture-hook for repair, and 10.8% to 15% in the all-inside meniscus repair device group.

      Conclusion

      This systematic review demonstrated that several approaches used to treat medial meniscal ramp lesions associated with ACL tears lead to positive clinical outcomes. Small, stable tears <2 cm in size may be managed with debridement alone. For larger, more unstable lesions, an all-inside approach has demonstrated positive clinical outcomes. Prospective trials are needed to determine the best management for meniscal ramp lesions. Additionally, further research is needed to better understand how to minimize the risk of technique-related complications (e.g., improper implant deployment).
