Week 13 update: First of all, our trip to Millbrook's 4th Line Outdoor Theatre and our friends in Peterborough went fine, although not pain-free. It was a 2-l/4 hr. drive, with Liam, his crate, food, toys, then around an hour and a half sitting outside having a wonderful dinner with our friends, next a half hour drive to Millbrook and a couple of hours sitting in the most uncomfortable, cheap plastic chairs at the outdoor theatre with a 20 minute break. After that a half hour drive back to Peterborough and another couple of hours socializing at the dining room table with wine and cheese! My poor knee was very uncomfortable but i didn't complain. I forgot to bring my tylenol. It took me a long time to get comfortable in bed and sleep although i had an ice pack which helped. Next day, same thing in reverse: sit outside in the beautiful garden in the countryside, inside for breakfast, then 2-1/4 hour drive home.
The best thing was
@Pheebs52, Liam was a rock star. They loved him and played with him outside. We had the e-collar on him so he stayed on the property, never jumped up on anyone and didn't grab anything (like he does at home.)

I don't think he even barked, even when the wild turkeys startled him. He had a ball running around the huge property and guess what...they invited him to come back. We're going back for another play on August 11 but not taking Liam this time ~ my niece will dog sit. (Sorry to get off topic).
Back to my update. I was exhausted after that trip but bounced back. I had physio twice this week, Monday and Thursday; same routine ~ massage, manipulation, laser, tens with ice packs below and above; lower the lights and cover me up ~ felt good as usual. Then i tried the bike, just rocked back and forth to discomfort. My r.o.m. increased a little more from 87 degrees to 92 degrees on my own and from 96 degrees to 102 degrees with manipulation (which i realize doesn't count but proves my knee will bend to that). Last night i went for a very long walk and was quite tired, sore and stiff today. Also, i had done all my new exercises a few hours before physio, which probably accounted for both the increased r.o.m. and the increased soreness and stiffness. I have not done any exercises today or long walks, will start tomorrow with either one and try to figure out what caused the soreness or is it just because i'm falling into old habits such as staying up until 1:30 a.m.? I am pleased that my r.o.m. is increasing a little each time. I'm also walking down the stairs, still very gingerly, with alternate feet so that i don't overuse my non-operated leg/knee.
