I am 51 and in need of a TKR. I have been needing one for around 15 years. Before I was too young.... Now after 15 years of suffering. I have gained a bunch of weight. (over 90 lbs) Now they tell me I weigh too much. I cannot walk without a cane, and soon to move to crutches(next week). Stairs are very painful. Sleep is ok.. I have been on hydrocodone 10/325's since Jan. I take 1 to 3 a day depending on my day. My quality of life has gone down hill mostly in the last 8 months. I have been working out fairly reg, and cut cals, but the weight is very stuborn coming off. my other knee is aching almost as much as my bad one. Tendon problems in both ankles and now my hip is starting to pop when I Walk. Should I push my doc to do it or should I wait ? Please help. The last few months my depression has been getting worse.
