Abstract
Objective:To explore respective feature of patellar attachment and femoral attachment of acute medial patellofemoral ligament(MPFL) injury on MR images,providing evidence for treatment.Materials and Methods: There were 32 injury cases of acute medial patellofemoral ligament injury examined with Italy ESAOTE 0.2 T MR or GE 1.5 T Twin Speed Infinity with ExciteⅡ MR during the period of 2008-01 to 2012-02.Medical patellofemoral ligament injury in patellar section-or femoral segment with dislocation of the patella,patella cartilage injury,medical collateral ligament injury was comparatively analyzed.Results: There were no significant difference of ratio of patellar dislocations(P 0.05),no significant difference of ratio of patellar cartilage injuries or(and) subcartilage bone effusions(P 0.05) between patellar attachment and femoral attachments,and the ratio of medial collateral ligament injuries accompanied with femoral attachment injuries was significantly higher than patellar attachment injuries(P 0.05).Conclusions: Evaluation on medical patellofemoral ligament injury in patellar section and femoral segment has some clinical significance.
