I'm scheduled next Thursday, Aug. 14 for a RPKR. I asked the doctor about why a unicompartmental rather than a TKR and he said that my medial side is bone on bone but the rest of the knee is normal. Except. That he did find that I had some signs of arthritis in the knee cap. He still felt a PKR was best for me, as he said I could still have a very good ROM as I'd be keeping all my ligaments and he felt it would be best considering I wanted to keep an active lifestyle. I think he knows I plan to run. He reminded me that running was not "recommended" on a PKR..and left it at that, very obviously. Anyway, I was thrilled to finally have a date...except my daughter may be getting induced to have my granddaughter the day before... I considered changing the date, but I can't. I need this too bad. I'm so tired of the pain and ready to have my life back again.
