It's unfortunate, but a lot of PKRs fail very early and have to be revised to a total (TKR), simply because they probably should not have been done in the first place.
Sometimes your arthritis progresses more quickly than expected, and affects the other compartment of your knee - or some surgeons don't have the special skill that is needed to do a PKR.
My first knee replacement was a PKR. It lasted for 11 years, which is longer than most. Having had a revision to a TKR, if anyone asks me, I usually advise them to consider having a TKR, not a PKR.
