Great milestone! And, I can relate. We have a very steep driveway and, prior to my TKR, I had to use a cane to get to and from the mailbox. I literally did a little jig the day -- three months post-op -- I was able to walk down the driveway like a normal person.For the last few years, walking downhill has been horrible with both knees. Just that particular angle on my knees caused huge pain. Today I noticed that my surgical knee was able to walk down the hill and absolutely no pain!!! Yes, there is still muscle tightness, but NO PAIN!
