I had my follow up appointment yesterday. A nurse took out my stitches, then the doctor came in and showed me some cool imagery from the procedure. He showed me where he snipped a bit and where he’d polished up some ragged cartilage.
I can start cycling and elliptical machines now. I can lift reduced weights until I work back to normal. I shouldn’t run for 3-4 weeks.
As far as causes go, he says it’s just wear and tear, maybe a bit of genetics, nothing particularly exciting.
I won’t see him again for this unless there is a problem. There won’t be any physical therapy, I’ll just work back into doing my usual things. It all worked out quite well.
