walking tall

I know it has been a while since I have added anything to my journal.I have gotten the walking thing down fairly well even if it is working against the hyd on my knee I have not been able to overcome that nid stance flextion where the knee breaks and straitens when your over top of it .Hard as I try I just can not get my knee to catch up.It has been a year and a month although I have come a very long way I still get frustrated with it.Any body got any ideas?
