Poster 321: MENISCAL RAMP LESIONS IN ADOLESCENT PATIENTS UNDERGOING PRIMARY ACL RECONSTRUCTION

Objectives: Meniscal ramp lesions describe a specific injury to the meniscocapsular junction at posterior horn of medial meniscus. The are strongly associated with anterior cruciate ligament (ACL) injuries and may affect biomechanical stability knee if left untreated. Despite increasing rates ACL reconstructions performed in adolescents each year, prevalence risk factors for this patient population is poorly understood. purpose study was determine children adolescent patients undergoing primary reconstruction. Methods: All ≤19 who underwent reconstruction single institutional between 2019 2021 were included. surgeries by three fellowship trained orthopedic surgeons. Patients considered have lesion one identified arthroscopically time Basic demographic data, preoperative imaging, other arthroscopic findings reviewed. Results: 247 consecutive excluded they had prior injury, surgery, fibular hemimelia, or incomplete documentation. A total 230 met inclusion criteria. Average age 15.7 years (range 4.0-18.2 years). 12% patients. Posteromedial tibial bone bruise on MRI femoral chondromalacia presence lesion, Figure 1A (OR = 2.6, 95% CI [1.15, 5.93]). striation pattern highly 1B 424.3, [50.99, 3531.3]). Sensitivity specificity detecting 68% 76% 99.5% condyle striations, respectively. Conclusions: our cohort 12%, mirroring historical reports adult bruising chondromalacia, especially pattern, should increase suspicion
