Debbie, I saw one of My OS's team at seven weeks. My next appointment is on 6 December, when I will be 15 weeks. At 113, I feel you aren't behind - compared to my 73 (and that's with an extortionate push). My PT reckons there is too much scar tissue now to progress any further. She does nothing like massage, electrical stimulation, etc. Just basic pushing the knee back, that's all.
Lately I have got out of the habit of icing, so am going back to that to see if it helps.
