HI---I had an MRI 4 months after an impact like knee injury and it showed a bone bruise and bone edema of the femoral condyle and tibial plateau, also a mild sprain of the MCL. In my case it also showed a simple linear tear of the posterior meniscus. My pain was pretty bad at first, then eased up, now it is like a stinging sensation that comes and goes. The pain is located right where the bones that are bruised come together. I don't know if the pain I feel on occasion is from the bone bruise or the meniscus tear. I don't want to rush into surgery as the MRI already shows arthritis and I am 49 yrs old now. I also read that bone bruises take a very long time to heal.
