With me, I found hydrotherapy very beneficial following the arthroscopic lysis surgery, and was in the pool 36 hours post op. The physio was not nearly as bad as it was following the TKR, I spent hours either trying to dangle my legs off the dining room table, or trying to pedal on an excercise bike. I experienced neuropathic pain, had my dosages of baclofen and amitriptyline increased and was able to bend my knee.
My knee bend still is not ideal at 96 degrees even at 4 months following the lysis surgery and nearly 10 months following my TKR. I have been told by my physio that my knee bend might never improve which is a great disappointment as I am relatively young (53).
