  "abstract": "Introduction: Persistent non-visualization of the posterior horn of the lateral meniscus in a knee without previous surgery is rare. Case Presentation: A 41-year-old man with obesity presented with chronic right-knee pain and recurrent giving-way eight years after an untreated complete anterior cruciate ligament tear. Examination showed positive Lachman, pivot-shift, anterior drawer, and McMurray tests. Magnetic resonance imaging demonstrated chronic anterior cruciate ligament discontinuity, a medial meniscal ramp lesion, and persistent non-visualization of the lateral meniscus posterior horn, with associated degenerative changes. Management and Outcomes: No previous meniscal surgery was reported, and no portal scars or hardware were identified. Arthroscopy had not been performed at the time of reporting; therefore, congenital absence could not be distinguished from severe acquired tissue loss, and postoperative outcomes were unavailable. Conclusion: Systematic review of all meniscal segments and arthroscopic confirmation, when clinically indicated, are essential before labeling an absent-appearing meniscal segment as congenital.",
