I had the traditional knee replacement 10 1/2 years ago and yes, I really believe that my passive machine helped. They say they do not use it any because you can get the same results with PT. However, this may be true. The machine definitely helped. I think it’s because the insurance companies are too cheap and do not want to pay extra for this machine rental.
My left knee replacement was so painful and I cried so much while in the hospital and rehab and home that I swore I would never go through that again! I just had the Nano Knee on my right knee one month ago and I am out about 120° or more I can get my leg straight, doing well walking the dog Doing some activity. Nano Knee replacement is less invasive less PT and less healing time. However, it is still painful but not near as much as a traditional knee replacement. The only time I ache is at night and I bought an ice cooling machine and now I can sleep all night. Please look into the Nano Knee or Jiffy Knee. It might be the answer to the traditional knee replacement.
