The results of hip replacements (hip arthroplasties) in England and Wales are already captured on the National Joint Registry (NJR). To improve further the quality of hip surgery in the United Kingdom, the British Hip Society has set up the Non Arthroplasty Hip Registry (NAHR) to monitor the outcome for patients of all other types of operations on the hip.
Cases from both the NHS and the independent health care sectors are included in this register, the success of which depends on gathering information on as many people having these operations as possible.
