Presence of contusion may also effect management of knee injuries often requiring prolonged rest even in absence of surgical correctible lesion and establishing diagnosis of bone marrow contusion may obviate further costly work up like arthroscopy. MR feature of bone bruising reflects increase in water content in marrow cavity as a result of haemorrhage, therefore water sensitive sequence like fat saturated T2W, PD weighted image or STIR are used [1,11,12]. Meniscal injury was unrelated to the extent or pattern of bone bruising. Age, type of bone bruise, and number of bruises also have prognostic value.
