Hi Tammy,
Sometimes a plateau happens, whether it's during your recovery or in your personal exercise regime. It sounds like you've maxed on your insurance coverage for the outpatient PT and after 50 sessions, they should be able to give you some sort of workable home plan to carry forward by yourself. It might help to be released from PT and the expectations that occur with that and just come back to yourself and do stretches and exercises that you enjoy and find helpful.
A while back I remember there was some talk of
Iliotibial band soreness/tighteness, were you able to look at the stretches in that thread? Is that what you think is the sensation that you feel in the side of your leg?
I also saw what I think you were describing as this stretch (without the pushing on the knee), this is a great one to bring home to help with many of the muscles in your groin and buttocks. Just resting your foot up there on your knee until it seems like it gets easier to do and your flexibility increases.
I am also a big advocate of using the foam roller for both the IT band issue and the groin tightness, if you are experiencing these as sore/tight places. In fact if you google foam roller stretches you will find all sorts of way to use the roller on different muscles.
The gimpy limp does take an amazingly long time to abate, for some, and while it's good to do some practice without the cane, it can also be helpful to just accept the cane as an assistive device for a little longer. You can certainly practice the walnuts cracking as you walk with the cane -- clenching your buttock muscles as if you are cracking a walnut with them.
How is your LLD -- do you have one?
