The aftermath of the manipulation of my knee has been pretty good. The anesthesia left me groggy for the given day but no pain afterward and I can still walk okay. Results in physical therapy have improved, so it's gone well.
Alas my knee has been slow to bend after my knee replacement. The next step is to forcibly bend the knee, ripping the scar tissue apart, under anesthesia. I am looking forward to the result if not the procedure itself.
