Description of intervention(s) / exposure
This registry will collate clinical information and patient-reported outcomes for private patients presenting with hip or knee arthritis, and determine the associated contributing patient/pathology/management factors at up to 2 years of follow-up.

Patients will undergo consultation for diagnosis and treatment, including the collection of demographic data, patient medical history, radiological findings and diagnosis as per standards of care. Clinical outcomes at baseline and post treatment follow up will be assessed via completion of general health, expectation/satisfaction and pathology specific questionnaires. Patients will attend for follow-up visits as decided by the clinician on an individual basis, and those participating in the registry will complete questionnaires delivered electronically at pre-determined time points (dependent on questionnaire; includes pre-treatment, and 3, 6, 12 and 24 months following definitive treatment). Clinical information will be collected within the clinic practice management systems during consultation or follow up as per standard operative or nonoperative treatment pathways, and data from eligible patients collated within the AORA registry for subsequent review and analysis.

Participants to the AORA clinical outcomes registry will be provided information stating the purpose of the clinical outcomes registry, and the inclusion of their clinical data for research and monitoring purposes. Patients will be provided an opportunity to decline the use of their medical records and clinical information for the clinical registry.

Statistical methods / analysis
The sample size will reflect the clinical flow of knee and hip arthroplasty surgeries performed by the participating surgeons. Sample size calculations were based on a rule of thumb of 10 treatment failure events per variable entered into a binary logistic regression model, assuming a clinical failure of 25% (hip) or 20% (knee) at up to 2 years followup. Failure rates were estimated from revision rates reported in the AOANJRR for the surgeon's most commonly used hip/knee implants, and rates of unsatisfied patients reported in relevant peer-reviewed literature. Binary logistic regression will be used to identify preoperative and early intraoperative or post-treatment characteristics affecting patient reported outcomes, and rates of treatment failure.
