Outcomes
Primary outcome [1] 304356 0
The incidence of patients that are deemed a "failure to cure" following definitive treatment, with failure to cure being considered if there is any of the following:
- Insufficient improvement in patient reported outcome measures (function or pain) when measured against minimally clinical important difference for the PROMs identified in secondary outcomes;
- Adverse findings on post-treatment medical imaging, as identified by radiologist and reported to the surgeon;
- Positive signs of instability, weakness or other primary pathology during clinical follow-up, measured by surgeon interpretation of ML stability and AP stability; or
- Failure to improve knee or hip range of motion, fixed flexion, extension lag and flexion contracture measured using a goniometer.

Statistical methods / analysis
Sample size calculation; This clinical quality registry has been designed to capture >80% of patients presenting to the participating clinic as per the inclusion criteria to provide adequate internal validity of the results and generalisability to patients presenting to a private clinic in a major city of Australia.

The registry will routinely report data quality with respect to the core dataset. This will incorporate data completeness, consistency and validity. Registry primary and secondary outcomes will be reported annually.

Analyses relevant to each patient cohort will be pre-planned specific to the prospective questions identified for each.

Summary
Brief summary
This is a prospective, observational cohort study assessing patient outcomes after joint replacement surgery. The purpose of this study is to assess clinical outcomes within the Investigator’s practice.
The primary objective of this protocol is the implementation of an ongoing registry to collate and store patient outcomes collected routinely as part of the standard clinical pathway for hip and knee arthroplasty at the Investigator’s practice. Outcomes will include objective joint function, pain, satisfaction, quality of life, radiology and revision surgery. The secondary objective is to integrate the clinical outcomes with analyses provided by the Australian National Joint Replacement Registry.
Recruitment will include all patients electing to undergo hip or knee arthroplasty surgery within the investigator's practice. Patients will undergo standard of care preoperative work-up, including the collection of demographic, medical history, radiology, pathology, and functional analysis. Patients will be required to complete the; EQ-5D 5L, and specific joint function outcomes will include Harris Hip Score (HHS), Oxford Hip Score (OHS), Oxford Knee Score (OKS), International Knee Society score (IKSS). Patient evaluation will be completed at the following time points: preoperatively and postoperatively at 2 to 6 weeks, 3 months, 12 months, 24 months and 5 years.
The clinical outcomes of individual patients will be monitored up to 5 years postoperatively.
