My grandmother, who will be 89 in October, just made it through her knee replacement with flying colors. I was quite worried about how she'd manage. I expected to find her exhausted and doped up but when I arrived at the hospital she was cheerful, chatty, and quite comfortable. With the help of a physical therapist she took 5 steps on he new knee today, which I find simply amazing. So much strength in that woman! I look forward to her being pain-free and mobile again.
