@saeternes: several answers Yes, swelling of leg is normal. Mine was moderate, I had more of an issue with the large bruised areas along the leg and foot to fade away. The foot especially took weeks until the last of the blood was resorbed. My incision was closed with surgical glue, and dressed with an XXXL super sticky, silver colored bandaid, so no ace bandage (and able to shower right away). The bandaid was changed by PT lady 8 days after surgery.
Regarding measuring the knee flex, usually (and in my case only) it is done unassisted. Whatever you can do on your own, that’s it. Sometimes it will also by measured with someone pushing on the knee, but that is always spelled out, to know the difference.
Wise decision to keep a log of things as they happen. I know for sure that at day 5 my walker was permanently parked in my bedroom, where it came in handy to use it in reverse, stationary, to hold on to the handles when doing bent leg lifts. I vividly remember walking into the outpatient PT room about 10 days after surgery without any implement, showing off by walking as normally as I possibly could. I had been a patient there several times over the years, and I like to see their jaws drop.

. (Unless one of my grandsons borrowed it to race down our long hallway). Stay with the amount of pain medicine that will let you function. Don’t stop taking it because you feel you ought to. Not everyone wants to tough it out like I did. My goal was independence, as in driving, so I lived with the sometimes painful consequence. Not sure that was a good idea.
