Of course underlying this indecision is the recurrent fear that I will not progress in ROM without PT. (been at 90 flexion and -10 extension for two weeks. )
For those of you who didn't do PT or did very little, what was your ROM progression like? I feel like I can get to -5 on extension, which is where my other knee is, but I am worried about flexion. Oh yeah, PT told me today that manipulating of scar was going to be very important to freeing up movement too (?!?)
It's not even 4 weeks yet since you had your TKR and you're already at 90 degrees! That is really very good. Most surgeons don't expect 90 degrees until 6 weeks.
I think that there is far too much emphasis placed on measuring ROM. Your knee will continue to improve and all that measuring just worries you.
Yes, I'm going to advise you to give your knee a complete break from all PT and exercises for a month, except for the things you do in your daily life. You see, it's not exercising that gets you your ROM - it's 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.
All the exercising you're doing, plus an over-keen therapist, are what is holding back your knee's healing and ROM. Doing too much exercise, and forcing your knee irritates your wounded soft tissues, which makes them swell up still more, which in turn lessens ROM. It's a vicious circle.
Knee recovery - Lose the Work Ethic!!
Instead of going to PT, spend extra time resting, icing and elevating your knee, to help reduce swelling.
I did no PT at all for my last TKR, and only went to two sessions for the one before that. Both my knees are strong and reliable. They straighten fully and bend to somewhere between 125 and 130 degrees. I don't know the exact number, because my ROM has never been measured. My surgeon doesn't measure (he forbids PT for the first month after surgery, too). He just says "show me what you can do. Function is far more important than the numbers.
Manipulating the scar is completely unnecessary, too. Your PT is misinformed.
Mother Nature is pretty good at doing her job of healing, without outside intervention.
I know many will say just drop the PT, but most Americans (perhaps not all) are under tremendous pressure from their surgeons to at least give it the old college try. Most surgeons would not be pleased with a forever bend of just 90 degrees and I'm fairly certain most patients wouldn't be either.
What do you want to do? Please your surgeon, or have a good knee recovery? Read the article I left above.
Who gave you the impression that your ROM would halt at 90 degrees if you don't go to PT? It just isn't so.
In any case, there's really no need to discuss PT with your surgeon. He/she can recommend it, but you are an adult and you are in charge of your knee. Not going to PT will not prevent your ROM from improving.
And ROM can continue to improve for a year, or even longer, after a TKR.
This is what one of our members wrote about the slow development of her ROM. (Thank you,
@Campervan ) As you can see, her flexion continued to improve for a long time.
"I had a slow recovery. Here's my flex measurements at various points:
92 - 8 weeks post op
105 - 10 weeks
107 - 5 months
110 - 6 months
112 - 7 months
116 - 9 months
119 - 11 months
118 - 1 yr
120 - 1yr 2 months
125 - 1 yr 8 months"
