Only in last week or so has the swelling in my knee decrease to the point where I have more than very limited movement. Previous to last week, I could only minimally (less than 10 degrees) deflect my knee joint.

The physical therapist I am going to suggested a "foam wedge" (approximately 12" tapering to 3" high over an approximate 24" length) placed such that the higer end abuts your butt and the lower end supports your ankles (depending on the length of your leg). You can also achieve a similar cofiguration with pillows. Having your knees higher then your ankles seems to take stress off the lower back.

I started going to an out-patient PT at 3 weeks. I had a lot of swelling in my knee and could not deflect it. I had two large knots on the tendons that run directly behind the knee. After a couple of sessions of ultrasound and massage by the PT those knots quickly dissapated.

Also the PT had some other tricks like a balancing board, a large execise ball (to work hamstrings while on back and quads against wall), incorporated an elastic band for a few exercises and a variety of other exercises that seemed to really isolate some weak muscles. Also, from the beginning, she put me on the upright exercise bike with the seat raised high (so as not to violate the 90 degree restriction) which seemed to pay dividends.

In conclusion, I found the PT to be invaluable. Also, since she has dealt with many hip replacements her knowledge level is high and she is much more accessible for asking questions then the surgeon.
