bertschb - thank you for your response - seems we are alike in our pre-op and post-op characteristics. Would be interested to know more about your recovery since you are approaching 6 months post-op.
Well, you asked for it so here's my story....
My surgery was 10/24/2016. I only had pain for a few days so in that regard I think I was very lucky. After surgery my knee was elevated 95% of the time I was awake and on ice for many, many hours each day.
I did PT from about day 7 to day 30 post op 3-4 days a week. The PT would help increase ROM for a day then my knee swelled up because of the PT and it went back to where it was. I stopped going because it didn't seem to be helping and because we were leaving to go south for the winter.
I iced my knee for five months and it's still elevated whenever I'm sitting which is the vast majority of each day. I'm retired and my wife does just everything for me while I'm recovering so I literally just sat at home with my leg elevated and on ice. No errands, no household chores, no cooking, no nothing. I just rested my knee waiting for it to heal.
At just over five months I got tired of sitting around waiting for my ROM to improve beyond 90 degrees so on March 1st I started hiking for 90 minutes and eventually two hours each day in the foothills outside town. It was soooooooo nice to be outside getting exercise again! My knee felt very strong. No pain at all but still at 90 degrees ROM so I had to be a little careful on the steep sections of the trail. I stopped hiking March 25th because we came home from our wintering spot. A week or so ago my ROM increased to around 100, maaaaaybe 110 if pushed. I don't know if that's because I stopped hiking or just because my knee decided it was tired of sitting at 90 degrees.
I've had a bit of a setback just in the last week. We arrived on Maui a week ago and I started going out into the ocean each day and playing in the waves. I was allowing the ocean waves to stretch my knee more than normal and my knee has been sore the last couple days. I'm guessing it's due to the wave action against my knee.
I still don't have enough ROM to ride my mountain bike. Still can't put my shorts on while standing up. Still have to slide the seat all the way back in the car in order to get in and out. But, I CAN walk full speed with no pain and we're on Maui for another three weeks so I have that going for me
My trajectory is positive. Overall I'm going in the right direction. But, at my current pace, I suspect it will be at least another six months before I have full range of motion and I wouldn't be surprised if it was another year. I may break all records for the slowest recovery ever from a TKR.
Am I glad I had the surgery? Yes. Am I disappointed in my ridiculously slow recovery? Absolutely. But, on March 1st I got tired of waiting for my ROM to improve enough to ride my bike and started hiking on the trails I rode my bike on. I finally decided to just move on with my life. I can walk now with no pain and I'm thankful for that. If my ROM improves to "normal" some day, that will be gravy but I'm no longer waiting for that. I've just changed up my exercise routine that required good ROM and moved on. I'm getting a season pass at my ski area next winter for sure. I plan to hike part of the Pacific Crest Trail this summer. I also plan to climb the South Sister in central Oregon this summer.
If you want to feel good about your recovery, just think of how pathetically slow mine has been

Good luck to you!
