title: Anteromedial Marginal Fracture of Medial Tibial Plateau without Significant Knee Ligamentous Injury in Hypermobility Patient: a Case Report and Review of Literature.
abstract: Anteromedial rim fracture of medial tibial plateau is a rare fracture pattern with only a small number of case reports in the literature. However, it is highly likely that is associated with specific significant soft tissue injuries, especially posterior and posterolateral corner structure, and medial meniscus injury. It is thought this fracture is caused by hyperextension and varus rotation mechanism. The previous reports highlight the typical pattern of severe concomitant knee ligament injury associated with this fracture that always require surgical repair to restore knee stability and function. In this report, we present an unusual case with a history of generalized joint laxity and acute anteromedial marginal fracture of medial tibial plateau without associated significant ligament damage, together with a literature review of this condition. We believe this case report introduces new insights into this unique fracture pattern.
