National Joint Registry Data Set - Knee

Overview

Introduction

The National Joint Registry Data Set collects information on primary Joint Replacement Surgery and revision Joint Replacement Surgery.

The majority of National Joint Registry Data Set items relate to the PATIENT's operation details and are collected in the OPERATING THEATRE.

The National Codes for National Joint Registry items match the National Joint Registry bulk upload codes / system generated codes.

PATIENTS must give their consent for this data to be recorded on the National Joint Registry Data Entry System (the electronic system for collection and transfer of data).

Note: the consent is for data in the 'Patient Identifiers' group. Where consent is not given, the 'Patient Details' group and the operation details are still recorded.

Operations included in the National Joint Registry database
