@ Celle thanks, mine is just a slow progression and that can be frustrating as well. I just want the rom to be a comfy max not a it bend there once to get a number, but instead I can bend it to that point regularly and as needed. And my Rom was really good before surgery, not sure I am going to get all of that back even at this point which I hadn't considered before now.
I don't know how many times I have to say this: You are
not having a slow progression in ROM. Your ROM is right where it needs to be at this point in your recovery.
I can only assume that your PT therapist has a schedule she/he wants you to meet and is pushing for you to improve more quickly.
Sometimes PTs get hooked up on the numbers, because improving the numbers is one way they can prove to the insurance companies that they are doing a good job.
That's all well and good for the PTs, but it can leave their patients feeling (as you do) that they are not doing very well when they don't meet the PT's artificial schedules. It's demoralising for their patients and not really good patient care.
Sheesh! It's only 7 weeks since you had this major surgery and already your PT has you feeling that you're falling behind. You aren't. You are doing just fine.
You will regain the good ROM that you had before surgery and that gain will eventually be permanent.
All it takes is time - time to recover, time for swelling and pain to settle and time to heal. Your ROM is there right from the start, just waiting for all that to happen so it can show itself.
Slow and steady progress is a good thing.
Remember that this is a year-long recovery, so you have all the time in the world.
Your knee is still a work in progress. Where you are now is not where you are going to end up.
