I had dislocated my knee cap on 21st of september. Almost 4 weeks are over .i am unable to lift my leg up on my own and also I am unable to bend my leg on my own. My MRI says that I have 1.marrow edema seen in patella and bilateral femoral condyle suggestive of trabecular fractures with bone bruise .2.partial tear of lateral collateral ligament noted. 3.grade-I-tear seen in anterior horn of lateral meniscus. 4.moderate knee joint effusion. Can you please tell me is all these things serious? What should I do? Could you please suggest me some exercises so that I can lift leg and bend my leg on my own. Please suggest me everything required please. Thank you so much.
