Hi,
I did not have any scar tissue on either knee. You will have nerve sensitivity for months down your calf that goes away. Pains meds before physical therapy and do as much physical therapy as your insurance allows. I had home health come in and he pushed me in the early days but the doctor was surprised what range I had. Ice, ice, ice ! Love my pack with sleeve and velcro wrap. Better than pain medications.
My doctor explained all surgery risk but fortunately or unfortunately 😆, my brother does hospital accreditation. He literally scares me to death about what can happen and ALL the risks of infection. He has me ask about their rates of infection!

As bad as my old left knee was I still had more lateral movement. So the old athlete in me still could do pickleball and other full movement even with pain. With my TLR I just don't have the mobility left to right with both knees replaced and my hip. If I go down both knees are so sensitive I can hardly get up. It wasn't the case with one. Just commit yourself to PT and doesn't mean to overdo it. Patience and time. Listen to the therapist and try to get extended time. Your body needs to heal they know what you need to be doing and when.
