@djn1954 - I'd like to invite you to this discussion to read through some others' experiences and those who had to face the possibility of a revision.

I struggled with scar tissue after my knee replacement in 2006. I had to manipulations and all sorts of devices to try and get my knee to bend more. I was fighting years of atrophy in my ligaments and muscles. I am now 18 years into my knee and still going strong, although there is some occasional discomfort as I have to imagine I am getting near the end of the knees lifecycle.

I only ended up with 100 for my flexion. I wish I would have got more, but my scar tissue got too strong and that is as far as I could push it without needing surgery to remove the scar tissue. I opted to not do that as I didn't want to risk infection.
