Some update if someone is following my tragedy
First week of PT has elapsed. I'm slowly progressing, I think. I have some improvement in flexing and extending, but nothing dramatic. PT sessions are still painful and weird. I can't help it feel that something will pop, snap or brake in there at any given moment. When the physiotherapist is flexing the knee and applying pressure I'm sure that my tibia will pop to the front. The whole knee is still hard as a rock when you touch it (or flex it). The patella has finally stared moving around a little bit when you push it with fingers. I still comfort myself that there can't be miracles in 7 PT sessions after 45 days of immobilization (and surgery, of course). Muscles are still quite sponge-like, especially on the thigh.
