I was wondering what are the exercise after total knee replacement surgery?

You will do many: Different exercises. However, there are two main areas that a pt will work with you. First, you will need to work on stretching your hamstrings, making sure you get your knee in full extension. The second, which is very close to this, is quadriceps strengthening. Overall gait stabilization is also important. Pre-surgery exercises programs have demonstrated success in better post-surgery outcomes.
