A knee replacement replaces damaged parts of the knee joint with metal or plastic parts. It can replace the whole joint (total knee replacement) or part of it (partial knee replacement). It is most often done for pain and stiffness caused by osteoarthritis, when other treatments have not helped.
Full recovery can take several months or more, and a knee replacement can last for 25 years. All knee replacements in England, NHS and private, are recorded in the National Joint Registry, which publishes outlier status for revision (repeat surgery) rates for total, partial (unicondylar) and kneecap (patellofemoral) replacements.
Hospitals in Yorkshire and the Humber
34 hospitals in Yorkshire and the Humber with published figures. Sorted by name. This is not a ranking: read how to read this first.
The NJR open data gives one total per hospital for all joint replacements (hips, knees, ankles, elbows and shoulders) together. It does not split hips from knees.

Across England
In 2025-26, NHS-funded care in England (NHS hospitals and NHS patients treated by independent providers; private patients are not included) recorded 103,876 episodes where the main procedure was total knee replacement (OPCS-4 W40 to W42). 2% were day cases. Half of the people admitted from a waiting list had waited less than about 134 days from the decision to admit them. These are national figures from Hospital Episode Statistics (NHS England, 2025-26, Open Government Licence v3.0); the same detail is not published for each hospital.
Hospitals identified as outliers across the UK in the NJR 2025 file (out of 403): Total Knee 5-year revision: 8; Total Knee 10-year revision: 25; Unicondylar Knee 5-year revision: 2; Unicondylar Knee 10-year revision: 5; Patellofemoral Knee 5-year revision: 1; Patellofemoral Knee 10-year revision: 1.
How to read this
- Not a ranking. The table is in alphabetical order. A higher volume does not on its own mean better care, and we do not combine the columns into a score.
- Volume bands. Cut points are the lower quartile, median and upper quartile of all 398 hospitals that reported to the NJR in 2025 in the published table, rounded. So about a quarter of hospitals that reported to the NJR in 2025 fall in each band. The exact number is shown under the band.
- Risk adjustment. Where a figure says “adjusted”, the audit has allowed for differences in the patients each hospital treats, such as age and other illnesses. Hospitals that take on more complex cases can still look different for reasons the adjustment does not capture.
- Bands and limits. We only say a result is higher or lower than expected when the source itself says so (for example NJR outlier status, NELA funnel limits, SSNAP levels, CQC survey bands). Where the source publishes a rate without limits we show the rate and the national figure, and say “No banding published”.
- Small numbers. A small hospital can have 0% or a high percentage by chance. Figures the source suppresses are shown as “Not published (small numbers)”.
- Trust or hospital. Volumes and outcomes here are for each hospital or team, but waiting times and the CQC inpatient survey are for the whole trust.
- Different periods. Each figure has its own period, shown next to it. Audit results describe operations done one to three years ago; waiting times are updated monthly.
- Private hospitals. NHS waiting times and NHS patient surveys do not cover private hospitals. Private hospital data published by PHIN cannot be republished here without a licence.
- Talk to your GP or consultant about what the figures mean for you. If you are referred for planned care in England, you can usually choose your hospital.
