Double Popliteus Sign in Multiligament Knee Injury

Case: We report 2 rare cases of lateral bucket-handle meniscus tears that had displaced into the popliteal space within the context of multiligament knee injuries. In combination with a lateral meniscal root repair, an arthroscopic inside-out repair and an all-inside repair were successfully performed. Conclusion: When a double popliteus sign appears on magnetic resonance imaging, the surgeon should anticipate using advanced and unconventional techniques to reduce the meniscus into the joint. In addition, readiness for a meniscal root repair is crucial.
