My recovery for this knee is extremely slow compared to my first knee and the two my husband had done. Some friends also had easy recoveries, but I do know two TKR people who had difficult recoveries, all through the same surgeon. At first I thought it was how the surgery was done. Although that has to be a big factor, I think the condition of the legs going into surgery makes a difference. If you can do squats and interval work before surgery, recovery is probably going to be much easier. If the knee surgery does not radically change the configuration of the knee, recovery will be quicker. The two who had difficult recoveries using our surgeon had radical changes in the leg positioning and were fine after one and two years.Your rehab and recovery are certainly not normal for the majority of TKR patients. If most of us had tried this we'd be in agony for weeks.

Sorry you are having so much trouble. Good luck completing the rest of your recovery.Ok Three months before my first TKR, at a bodyweight of 160lbs, I back squatted 275lbs for 5 reps, below parallel, and was in great shape from kayak racing. I've since had a horrible experience with five surgeries over three years, and I'm still recovering.
The "window of opportunity" refers to the time soon after surgery that gaining ROM is quicker. As time goes by after surgery gaining ROM is slower. I am still working on my first knee, almost 4 years after surgery. It is slow but not impossible.
I used pilates to gradually stretch and strengthen my knee and I have great ROM (0 extension and 150+ flexion).Many people say theirs is improving but details on how they make that happen are missing. I
