Presentation
Road trafic accident 2 months back, complaints of persisting pain and walking diffuculty
Patient Data
Depressed fracture of lateral tibial condyle with irregularity of overlying cartilage and mild surrounding marrow edema.
Mild marrow edema is also seen in intercondylar region of tibia.
Low grade sprain of tibial attachment of posterior cruciate ligament is seen.
Fluid is seen between posterior horn of lateral meniscus and posterolateral joint capsule.
Fluid is seen underneath body of lateral meniscus, between body and lateral tibial condyle with possible tear of lateral meniscotibial ligament.
Linear hyperintensity seen in posterior horns of medial meniscus not intersecting with articular margins (Grade 2 signal).
Mild thinning with intrasubstance fat is seen involving patellar attachment of medial patellofemoral ligament likely related to old sprain.
Partial tears of posterolateral joint capsule seen.
Hyperintensity is seen along inferior patellar plica in keeping with inferior patellar plica injury.
Mild thickening and hyperintensity is seen at tibial attachment of patellar ligament with adjacent bony prominence possibly related to Osgood Schlatter disease.
Mild joint effusion is seen.
Case Discussion
Depressed subacute fracture of lateral tibial condyle with irregularity of overlying cartilage and mild surrounding marrow edema.
Fluid is seen underneath body of lateral meniscus, between body and lateral tibial condyle with possible tear of lateral meniscotibial ligament in keeping with meniscotibial avulsion. This has been described as the 'floating meniscus'.
Fluid is seen between the posterior horn of lateral meniscus and posterolateral joint capsule suggesting the possibility of meniscocapsular separation.
