Following a previous post, a number of people have asked me to post the links to the Swedish and Australian Joint Registries. Hopefully the mods will make this a sticky.
In Sweden and Australia, it is a legal requirement that every operation and knee is recorded. The UK also has a registry, but suppying information is voluntary (20% of cases go unreported, you can make your own mind up why some might not be reported)

Every company likes to tout figures on their success, normally studies by surgeons who are friendly to them, however, the registries include every single surgeon using the device, good, bad, or indifferent. They include tens of thousands of operations so will help nullify unusual events.
Its incredible to see that some knees that are commonly used in the UK have more than double the failure rate of others, must cost thousands in recovery costs.
Anyway the reports are below,

The Swedish Joint Registry
  http://www.knee.nko.se/english/online/uploadedFiles/113_SVK2009ENGL1.0.pdf
Gives results to 10 years, total knees are page 30-33 (or 34- 37 in acrobat). There are also some easy to understand graphs
Uni knees are page 34 (38 in acrobat)

Australian Joint registry
http://www.dmac.adelaide.edu.au/aoanjrr/documents/aoanjrrreport_2009.pdf
Total Knee results to 8 years are on page 145 (161 in acrobat)
They have a list of knees to avoid on page151 (167)
Uni Knees are on page 123 (139 in acrobat)
