Any knee doctors out at hand that can tell me if my doctor is doing the right point?

On the 3rd I twirled around and dislocated my knee panama. My doctor had an x-ray done and I've have an immobilizer on for the last 3 weeks. Now he say that I will need surgery, but he say that in proclaim to do the surgery I need to bend my leg. It's VERY aching, and I don't know if bending it may make it worse. He hasn't done an MRI but, which I thought he was supposed to do as soon as the swelling go down. He says it's a medial something femoral ligament scratch. I'm wondering, is it right that I should be bending this if it still seems to dislocate effortlessly? (I was in recent times sitting on my bed and it had the immobilizer on it and the knees cap popped inconsistent again twice. The doctor dissmissed it saying that that be next to immpossible, but I feel and saw it!) Shoudn't I have an MRI first to pinpoint the problem until that time trying to bend it? The knee panama still isn't in the "groove" it's supposed to be, the doctor said. So should I be moving it and taking the immobilizer stale? Help!
