The Non-Arthroplasty Hip Registry
Better Evidence.Better Understanding.Better Hip Care.
The UK's national registry dedicated to understanding outcomes following hip preservation and other non-arthroplasty hip procedures, helping clinicians, researchers and patients learn from real-world evidence.
Established by the British Hip Society

How can we help?
One registry. Shared knowledge. Better decisions.
The registry brings together surgeons, patients and researchers around a common purpose: building a reliable, shared record of what happens after hip preservation surgery.
Our purpose
Understanding what works. Improving what comes next.
Hip preservation and other non-arthroplasty approaches are used to treat a wide range of hip conditions. Outcomes following hip replacement are already captured by the National Joint Registry. The NAHR exists to study the rest.
Following outcomes over time can support clinical learning, inform conversations between patients and surgeons, and guide future research. The value of the registry grows with the number of people whose operations are recorded.
- Understanding treatment outcomesRecording outcomes by operation and diagnosis, including any further surgery.
- Supporting evidence-informed clinical practiceGiving surgeons feedback that can help define which patients may benefit from a given procedure.
- Advancing long-term researchBuilding a longitudinal record that can support future study and open publication of outcomes.
From data to evidence
Transforming clinical information into meaningful evidence.
Each contribution follows a structured pathway: from the operation itself, through the patient's own account of their recovery, to aggregated reporting that the clinical community can learn from.

Understanding hip preservation
Protecting the natural hip begins with understanding it.
Non-arthroplasty procedures are operations on, or around, the hip that do not replace the joint. They include interventions such as hip arthroscopy, a keyhole procedure inside the joint, and osteotomy, in which bone is carefully reshaped or realigned.
These procedures may be considered for selected patients, depending on their condition, anatomy and circumstances. Decisions are always made between a patient and their clinical team.

Patient involvement
Every patient experience contributes to a clearer picture.
With your consent, your surgeon records information about your operation. You may then be contacted, ideally by email, at regular intervals afterwards to share how you are progressing. Over time, these accounts help build a long-term understanding of surgical outcomes.
Information for PatientsParticipation is voluntary
Information is only entered on the registry where a patient has given consent.
Clear governance
The British Hip Society is the registry's data controller and Amplitude is its data processor.
How your data may be used
The current patient information explains that registry data may be used to evaluate the success of surgery and for medical research, and how it is anonymised for that purpose.
"Amplitude is processing your personal data under the lawful basis of legitimate interests under instruction from our registry, hospital and other clinical customers."From the current NAHR patient information

Institutional relationship
Established by the British Hip Society.
The British Hip Society set up the NAHR to improve further the quality of hip surgery in the United Kingdom, by monitoring patient outcomes across all types of hip operation other than hip replacement.
The Society is the registry's data controller. Amplitude acts as its data processor and operates the secure system used for data entry and patient follow up.
