We performed a retrospective magnetic resonance imaging and clinical review of a consecutive series of 27 dislocatable knees presenting to a single level\u2010one trauma center from 2005 to 2008. Post\u2010injury magnetic resonance imaging studies were reviewed by two fellowship\u2010trained musculoskeletal radiologists to assess injury patterns to the posteromedial corner. In our series, injury to at least one structure within the posteromedial corner was observed in 81% (22\/27) of cases while injury to the superficial medial collateral ligament alone was seen in 63% (17\/27) of cases. Furthermore, injuries to the posterior horn of the medial meniscus were associated with a tear of the meniscotibial ligaments in all cases and with a tear of the posterior oblique ligament in 67% of cases. All patients with grade III laxity (&gt;10\u00a0mm medial opening) under an examination under anesthesia had a complete tear of the posterior oblique ligament and meniscotibial ligament in addition to a medial collateral ligament injury. Injury to the semimembranosus attachment alone was not associated with clinically significant laxity under an examination under anesthesia. Our findings demonstrate that injuries to the posteromedial corner are common in the setting of traumatic knee dislocations. Interestingly, high\u2010grade medial instability during an examination under anesthesia and injury to the posterior horn of the medial meniscus may be important indicators for further posteromedial corner injury.<\/jats:p>","DOI":"10.1007\/s00167-009-1011-x","type":"journal-article","created":{"date-parts":[[2009,12,14]],"date-time":"2009-12-14T09:34:23Z","timestamp":1260783263000},"page":"1098-1104","source":"Crossref","is-referenced-by-count":29,"title":["Injury
