So I managed to mangle my knee somehow in the beginning of August. I saw the doc for it late that month as it wasn't getting any better, and did the recommended physical therapy for it (which didn't help). I went back to my doc and let her know in the beginning of December, and she finally ordered an MRI for me.
MRI was Wednesday, got the report yesterday.
Good news is that all my tendons and muscles and meniscuses and other soft parts are intact.
Bad news is that when I injured it I apparently put so much pressure on the joint that my femur is still bruised inside of the joint. A bone bruise, especially a large one, takes a very long time to heal.
So I just get to deal with being gimpy. Only time will heal this, according to the doc.
