I am 12 days out, had a patellar tendon autograft. I'm 28 and had a complete ACL tear and MCL sprain, and I went to physical therapy for about 6 weeks prior to the ACL reconstruction.
On Friday (10 days out) I had a decent PT session. I warmed up on the stationary bike and for the first time was able to pedal a full revolution. My physical therapist then made me push for 50 painful revolutions. My flexion improved to 109 degrees (from 105 degrees a my prior session) and I did some leg presses with low weight. My goal is to ditch the crutches by the end of this week.
Shana, I feel the same with respect to the swelling and front of the knee soreness, as well as the general instability with crutches. The knee tends to swell up at night and has been affecting my sleep - last night I woke up with swelling at 2:45am and couldn't get back to sleep until 4:30am after icing it. So you are not alone there, and from what I understand the knee should continue to swell up for several weeks.
As for the painkillers - I used plenty in the days after the surgery (which I probably needed due to the tissue graft). I thought I was finished with them until my first follow up with surgeon. He prescribed me some more and recommended that I take them before my PT sessions in order to make the bending exercises more manageable.
