TI  - Patellotibial contusions: a rare cruciate ligament injury pattern.

AB  - OBJECTIVE: Patellotibial contusions are a recently described contusion pattern in 
      anterior cruciate ligament (ACL) tears. The purposes or our study were to 
      determine if patellotibial contusions are specific to ACL injuries, determine the 
      internal derangements in patients demonstrating this contusion, and suggest a 
      mechanism of injury. MATERIALS AND METHODS: We conducted a retrospective search 
      of radiology reports over a 6-year period to identify patients with patellar 
      edema described on magnetic resonance (MR) imaging. Only individuals with 
      patellar and tibial edema were included in the study group. These MR examinations 
      were then reviewed for associated internal derangements. RESULTS: From March 2007 
      to June 2013, 1914 MR examinations of the knee were performed. Two hundred 
      seventy-one reports described patellar edema. Seven individuals had edema of both 
      the inferior pole of the patella and the anterior tibial plateau. Three 
      individuals were involved in motor vehicle accidents (MVAs); 4 patients had a 
      history of an axial load or sports-related injury. All 3 patients involved in 
      MVAs had posterior cruciate ligament tears consistent with posterior translation 
      of the tibia. The non-MVA individuals had tears of the ACL with internal 
      derangements similar to other ACL deficient knees, however, with more widespread 
      osseous contusions. CONCLUSIONS: Patellotibial contusions are high-energy 
      injuries resulting in cruciate ligament tears. These contusions occur exclusively 
      in patients with ACL tears when individuals with a history of direct impaction to 
      the knee are excluded. Axial loading of the extended knee may be an important 
      mechanism of injury in these individuals.
