Hi Marcia,

I'm shocked that your surgeon would green light tennis after a TKR. My surgeon told me to not participate in sports resulting in impact to the knee - so no running, no court sports. On top of impact, tennis puts a lot of lateral stress on the knee.

And I'd get a second opinion on what to do. Did your Dr even take an Xray? There are ortho surgeons who specialize in what is called "revision" knee replacement surgery. I'd seek one of these surgeons out.

All the best to you. FWIW I'd stay away from court sports, even pickleball. Joe
