Hi knee buddy!
Your second knee sounds rather like my first. I get pain still on the lateral edge, as well as swelling and stiffness at times, which I'm told is the IT band where it goes across the femoral condyle (or something like that). When I saw the surgeon in October he said it should settle after 18 months, so maybe yours will be the same?
I wouldn't say mine is a searing pain, although I can't remember what it was like 6 months ago, but it's there most of the time. Patience might be a virtue, but it's not always easy!
