I was in PT with a 70 year old woman. She really worked it and was walking without a cane in two weeks. I guess I'm comparing myself to others. I want my legs to be really strong. I want to climb and dance again, etc. Everyone here believes in exercising daily.....squats, leg presses, bike, walking. Feel pulled in two directions. And the knee buckled again today. First time since two weeks in.
Don't compare yourself to what a 70-year old is doing. For some reason (and I don't know what it is), some older people do seem to recover more easily. Of course, you don't know what her knee was like before her surgery. It could well have been less damaged than yours was.
Your legs will be strong again and you will be able to do all the things you want to - but all in good time.
Complete healing takes a full year. Nothing you do will speed that up, but doing too much can slow it down.
It's still less than 3 months since your surgery and that's far too soon to be doing lots of strengthening.
Your knee needs to be well on the road to healing before you start strengthening exercises.
You really don't have to work hard in order for your knee to recover either full function or strength. All that exercise makes you feel as if you're doing something to help, but it isn't really necessary. Your knee will recover anyway, as long as you don't do anything to prevent it.
Squats and leg presses are really bad for recovering knees. They put far too much stress on the knee, so please don't do them.
As you've been working since quite early in your recovery, I think that was more than enough exercise for your knee, without adding exercises.
What you've been doing until now obviously hasn't worked well for your knee, so you have nothing to lose by trying something different:
- Stop all the exercising and just let the activities of your daily life be all the exercise you knees get. Believe me, that will be enough!
- When you're at home, continue to rest, ice and elevate your knee.
- Continue to use a stick or other walking aid, until your knee doesn't buckle any more.
Try that for a month and see how you get on.
