Description of intervention(s) / exposure
1. Patients presenting with episodes of giving way (with or without primary anterior cruciate ligament rupture), managed with arthroscopic ligament reconstruction. Outcomes monitored up to 2 years via patient-completed questionnaires and medical record review.

2. Patients presenting with degenerative knee conditions (OA, RA) failing non-operative management, managed with total knee arthroplasty. Outcomes monitored up to 2 years via patient-completed questionnaires and medical record review.

3. Patients presenting with knee osteoarthritis affecting predominantly the medial or lateral compartment (with or without patellofemoral joint involvement), eligible and electing to undergo realignment osteotomy. Managed with opening-wedge high tibial osteotomy, or closing wedge distal femoral osteotomy. Outcomes monitored up to 2 years via patient-completed questionnaires and medical record review.

4. Patients presenting with complaints regarding a previously implanted total knee replacement; reviewed by a consultant orthopaedic surgeon and offered surgical or non-surgical treatment. Outcomes monitored up to 2 years via patient-completed questionnaires and medical record review.

5. Patients presenting with knee conditions not eligible for inclusion in other cohorts. Managed operatively or nonoperatively. Outcomes monitored up to 2 years via patient-completed questionnaires and medical record review.

Outcomes
Primary outcome [1] 322549 0
The incidence of patients deemed a "failure to cure" following definitive treatment. Composite outcome consisting of insufficient improvement in patient reported outcome measures (function or pain; IKDC, SANE, KOOS/KOOS-12/KOOS-JR, ACL-RSI, MODEMS, Marx activity as relevant to pathology, movement restrictions as measured by goniometry); adverse findings on post-treatment medical imaging (eg. implant loosening); positive signs of instability, weakness or other primary pathology during clinical follow-up
Timepoint [1] 322549 0
12months following definitive treatment (non-operative OR surgical), depending on the specific pathology.
Secondary outcome [1] 378908 0
Complications and adverse events: any deviation from the ideal postoperative course that is not inherent in the procedure and does not comprise a failure to cure. E.g. surgical site infection as per the criteria described in Frangiamore et al 2015, intraoperative implant breakage, etc. This data will be obtained through medical records, and may be reported by participants during follow-up appointments with the specialist.

Statistical methods / analysis
Sample size calculations were based upon a rule of thumb of 10 treatment failure events per variable entered into a binary logistic regression model, assuming clinical failure rates for specific procedures taken from similar cohorts reported in the literature. Final target sample sizes for each cohort were calculated to have 80% power to detect a significant effect for 5 predictor variables, allowing for up to 10% protocol non-compliance and a 2-sided alpha of 0.05.

Summary
Brief summary
The primary purpose of this study is to analyse and report on outcomes following treatment for patients presenting to a single orthopaedic surgeon, Mr Timothy Lording, for management of conditions affecting the knee.

This clinical registry will collate and store patient outcomes collected routinely as part of the standard clinical pathway for knee treatments. Outcomes will include objective joint function, patient reported outcomes (pain, satisfaction, quality of life), radiological findings and rates of revision surgery or complications.

The main hypothesis arising from the registry is that specific factors present before treatment will predict the likelihood of a patient experiencing a positive, or negative outcome (whether clinically indicated or patient-reported) following surgery.
