@JusticeRider @Jockette Found this paper weighing up the pros and cons of PKR versus TKR. If you Google the title you can get the full pdf free and it is not that technically challenging to read.
One of the points of interest is that because PKR are easier to revise the revision rates may be artificially raised and more PKR than TKR are revised even if the Oxford knee score is the same i.e.- people may be told to live with a poor outcome on TKR whereas a surgeon is more likely to attempt a revision of PKR.
Another interesting point is because there are more revisions of PKR there is a perverse incentive to stop doing PKRs - as revision rate is seen as a marker of surgical ability or lack of it. Whereas in fact other outcome measures may be worse with TKR.
The only problem with nearly all the papers I have found on PKR is that they look at the most common type ( medial) rather than lateral or patello-femoral.
