Yes, you will continue to improve. I have been through a lot of surgeries in my lifetime. It usually takes a year plus to recover from a surgery as traumatic as this one - and this tkr surgery has been one of my most traumatic surgeries - anytime a surgery involves breaking a bone, it makes it really, really, extra painful vs. just a soft-tissue surgery.
Hopefully, you will continue to make positive strides (pun intended) in your hamstring progress. =) My big issue has been my IT Band. (Thanks again Josephine for those IT Band stretches/exercises.)
Thank you for the positive news. (Maybe you will feel like changing the title to your thread?) =)
