I'm 66 and had TKR, left knee, back on 6/5, but the surgery did not go perfectly. As the surgeon was doing a "medial release", remove tissue with an electrical cutting tool, it arced and blew out the side of my knee. So I had many bonuses: A bonus incision, bonus bleeding, bonus swelling, bonus pain. So, I was behind schedule on everything-the first two weeks are just a fog of pain and begging for my percocets a few minutes early...Would post a pic, but this site needs to have pictures hosted?
Now, i'm caught up at 8 weeks and thinking about trying to get up on the bike. Have been riding a recumbent stationary at PT and my flex is around 120 degrees, so i should be ok. In theory. My hybrid is setup with 170mm cranks.
Very apprehensive about falling, but I need to get back on it. My wife is definitely not a fan of the idea.
