Defiantly not fiction.

Some people recover better / faster than others. I did not say that his doctor encouraged him to play tennis 2 weeks after surgery. I said that he was back on the tennis court 2 weeks after surgery.

I am sure you will believe that this is fiction too. It is not. I had a robotically assisted left TKR in 2022. (I had done exceedingly well with a robotically assisted right TKR in 2018). My surgeon agreed that I did not have to stay overnight in the hospital if I could walk (with a walker) around the entire post op area. I did, and I went home. 3 days later I walked into PT without a walker. I did 2 weeks of PT and was discharged. Even my surgeon was surprised. A year after surgery I was walking 5 miles a day but I really wanted to get back to running. At my 1 year follow up, I asked if running would damage the knees. I was told that it would likely wear the replacements out a bit sooner, but if I really wanted to he was supportive of it. (My TKRs are both titanium.). I now alternate between walking and running every other day. I have been doing this for 10 months and my knees are in great shape. As I said, different people recover differently.
