Continuous Passive Motion

I have been quite fascinated with the continuous passive motion machine that is part of my immediate post-surgery therapy:

Basically, it's a fun little device that saves me the trouble of having to flex and extend my own knee. In theory, scar tissue won't form and circulation should increase into the affected area allowing more toxins to leave and more nutrients to enter.

I have been prescribed to gradually build up to a 90+ degree bend in two to three weeks from the date of my surgery.

Here's how I've been doing so far:
(Mon) December 15 - 50 degrees [date of surgery]
(Tue) December 16 - 55 degrees
(Wed) December 17 - 60 degrees
(Thu) December 18 - 65 degrees
(Fri) December 19 - 75 degrees
(Sat) December 20 - 80 degrees
(Sun) December 21 - 80/85 degrees
(Mon) December 22 - 85 degrees
(Tue) December 23 - 90 degrees

I'll see how close I can get to comfortably get close to 125, which is the maximum setting on the machine. I get my sutures off on Monday, so I'll also find out if I'll need to keep the CPM much longer. (It costs $35/day to rent!)
