Abstract
Background: Ramp lesions are characterized by disruption of the peripheral meniscocapsular attachments of the posterior horn of the medial meniscus. Ramp repair performed at the time of ACL reconstruction has been shown to improve knee biomechanics.
Hypothesis/Purpose: Primary objectives of this study were to evaluate the incidence and risk factors for ramp lesions in a large series of patients undergoing ACL reconstruction, Secondary objectives were to determine the re-operation rate for failure of ramp repair, defined by subsequent re-operations for partial medial meniscectomy
Study Design: Case series
Methods: All patients underwent trans-notch posteromedial compartment evaluation of the knee during ACL reconstruction. Ramp repair was performed if a lesion was detected. Potentially important risk factors were analyzed for their association with ramp lesions. A secondary analysis of all patients who underwent ramp repair and had a minimum follow-up of two years was undertaken in order to determine the secondary partial meniscectomy rate for failed ramp repair.
Results: The overall incidence of ramp lesions in the study population was 23.9% (769 ramp lesions in 3214 patients). Multivariate analysis demonstrated that the presence of ramp lesions was significantly associated with the following risk factors: male gender, patients aged under 30 years, revision ACLR, chronic injuries, pre-operative side-to-side laxity >6 mm and the presence of concomitant lateral meniscus tears. The secondary meniscectomy rate was 10.8% at a mean follow up of 45.6 months (24.2-66.2). Patients who underwent ACLR + ALLR had a greater than 2-fold reduction in the risk of reoperation for failure of ramp repair as compared with patients who underwent isolated ACLR (hazard ratio, 0.457; 95%CI, 0.226-0.864; P = .021).
Conclusion: There is a high incidence of ramp lesions in patients undergoing ACLR. The identification of important risk factors for ramp lesions in this study in an individual patient should help raise an appropriate index of suspicion and prompt posteromedial compartment evaluation. The overall secondary partial meniscectomy rate after ramp repair is 10.8%. Anterolateral ligament reconstruction appears to confer a protective effect on the ramp repair performed at the time of ACLR and results in a significant reduction in secondary meniscectomy rates.
