I had a total knee replacement and the plate removed from my leg 4 weeks ago. It has been a year and a half since my tpf. My knee flexes 130 and straightens 0. I walk without a cane or walker (my surgeon did not cut any muscle), My leg is straight again. I still have pains in the area of the plate especially at night. My doctor is pleased and says I need to give my body time to heal. It is already better than before the surgery.
