Most commonly it is impossible to fully extend the knee; more accurately described as stiffness (termed 'pseudo locking') due either to a small effusion (requiring increased force to bend the tense joint capsule) or to pain inhibition as the femoral condyle compresses the torn meniscus. In cases where a torn meniscus has locked the knee, walking will be affected. Additionally, the large radial tear dramatically undermines the ability of the meniscus to distribute hoop stress. London;1897. The menisci are C-shaped fibrocartilages with concave upper surfaces and flat undersides that match their respective interfaces with the femoral condyles and tibial plateau.
