4. Hip Revision Ratio: Benchmarking Success
This graph plots Mr Lawrence’s standardised hip revision ratio against national data. Each dot is a surgeon; lower is better.
Key points:
-
Mr Lawrence’s data points consistently fall well below the green national average line, indicating a lower-than-expected revision rate.
-
This places him among the best-performing surgeons for hip replacements, with a notably high success rate and low complication profile.
