    • All Hip, Knee, Shoulder and Ankle joints entered
    • UK registry started in 2002
    • Now biggest in the world, 1.2 million procedures
    • In 2012 it produced the first institution and individual surgeon data on joint failure rates(revision)
    • Results given funnel plots and figures 

Below is Mr Oakleys results for hip replacement by way of example (Data from March 2013)

funel graph hip 2013
This looks complicated but gives a lot of information. The horizontal axis represents the expected number of revisions bearing in mind the number of primary hips the surgeon does, the vertical axis is the actual  revision rate of that surgeon. The green line represents the "expected number" of revisions based on the surgeons case load. Above this line means more than average failures. Each dot is a surgeon, blue dots are deemed to have an acceptable revision rate, red dots are outliers, purple are off the scale.
I am proud to say I am represented by the black triangle.
(To put this in figures: out of 523 qualifing hips in the register, 2 have had to be revised)
A surgeon performing similar numbers as me, with results on the green line, which represents average results, would have had 10 revised, and would have become red if about 20 had been revised.
