a. Drive through test positive on a right knee. b. Crescent moon sign. c. hypermobile lateral meniscus on a left knee. Arthroscopic findings of the right knee; the image is viewed from the anterolateral portal. a: Arthroscopic view, lateral gutter, right knee, of torn popliteomeniscal fascicles (white narrow arrow). b: Arthroscopic view, lateral gutter, right knee, showing “crescent moon sign” (white broad narrow). c: Arthroscopic view of disruption of the popliteomeniscal fascicles of the lateral meniscus in a left knee. Significant subluxation of the lateral meniscus can be demonstrated by anteromedial traction applied by a surgical probe
