Good afternoon sir, I am a student, named Diptesh. For about 1 year ago...while playing football I fell down while blocking a ball and by knee twisted such that I got injured but didn't primarily gave importance. From then on I started  feeling that my knee joint is filled with fluid. Sometimes it pained while playing or doing something and sometimes it unstabilises. I went to many doctors here, and most of them said I don't have any serious injury and no complete ligament tear. Though some of them told that yes I have ligament tear. I did x-ray, USG of knee where I found a little fluid as well as MRI, where it says that ACL is completely torn but still most doctors said that there is no such tear. Now after rehabilitation and excercise I started playing football using a knee cap.. Everytime I get mild injury and recover but day before yesterday I got some serious injury and I am unable to completely bend knee, feeling extreme pain. What can I do sir? I want to play football again,? Pl
