What is the difference between symptoms of knee sprain and a torn ligament?
Patient: What is the difference between the symptoms of a knee sprain and a torn ligament(acl) - I fell a week ago and I can walk on it with a brace, it hurts when I turn it, I can t bend it back all the way and i all most can straiten it. I heard a pop when I fell? Doctor: Hello,  As there is surely a difference between the ligament sprain and torn ligament. In a sprain, there will be pain and swelling which will subside after some days and the knee function will resume. In torn ligament, there will be no movement in the knee even after some time. After the torn ligament there will be grinding of the knee.  Doing MRI scan will help reveal the status of the knee internal structures and help to plan the next course of action.  In ligament sprain, there is conservative management and in a torn ligament, there is surgical management.  Hope I have answered your query. Let me know if I can assist you further.
