Disruption of the anchoring points of the menisci of the knee has been hypothesized to result in subluxation of the affected meniscus from the articular surface. A case report of such an extrusion of the medial meniscus is presented. Medial subluxation of the meniscus from the tibiofemoral articulation occurred as a result of avulsion of the posterior horn with concomitant medial collateral and posterior cruciate ligament injuries.
