title: Avulsion of the posteromedial tibial plateau by the semimembranosus tendon: diagnosis with MR imaging.
abstract: Two sports-related knee injuries resulted in small fractures at the posteromedial corner of the tibial plateau. Magnetic resonance imaging demonstrated findings consistent with an avulsion injury at the semimembranosus insertion, as well as a similar pattern of internal derangement in both cases.
