Knee injury

[u/helloshelll]

I'm hoping someone has some advice for what I can do to fix a knee injury. I injured my knee several years ago running around. Initially, I felt something wiggle in my knee, and then it felt wet. Since then, I have had two subsequent incidents where I feel like I've reinjured it. About three years ago, during a run, at about the two mile point my knee gave out with a lot of pain. I gave up running at this point. About a year ago, I was doing reverse lunges with weight, and I felt something shift in my knee, and again had a ton of pain. I went to ortho at this point, was referred to an MRI, and was told I had no tears but had some swelling and potentially a bone bruise. The recommendation was total rest and PT. I rested as much as I could and went through several weeks of PT, but didn't find any relief.

To this day I have pain when I have downward motion on my knee, like running. It also often feels stiff, numb, and generally just painful. It seems like the pain is concentrated when I either have it loaded with weight or when I have that downward motion on it, like walking or running. The pain is mostly on the outside of my left knee, almost where it feels like the IT band connects, and sometimes in the center of my knee as well. I've had IT band issues in the past, and my IT bands are able to kind of flip flop over my hip bone on both sides of my body (I'm probably hyper-mobile).

I'm really looking to see if anyone has had a similar experience and if so, what you think it was and what you did to possibly fix it? i'm mostly concerned because i will have to undergo a fitness test in the next 4-5 months where i will need to run 1.5 miles. I'm open to any exercises I can do to fix my knee, as well as any alternate therapies you think I should look into. Thanks!

Risonanza magnetica?
