We all go into the surgery with different bodies. While I imagine the "procedure" itself is pretty consistent, our experiences in surgery and post op are unique. My knees aren't great, and I walked with a bad limp prior to surgery. I was heartbroken when I realized at about 4 weeks that I was not progressing as quickly as I was led to believe I would by my OS, PT, and all the straight A student veterans of hip replacement. Each day I remind myself that slow and sure can get us where we want to be, too. Hang in there!
