Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pain intensity and pain interference are assessed using the Brief Pain Inventory at baseline and 12 months after randomisation. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Pain and physical functioning are measured using the Brief Pain Inventory (at baseline and 6 months) and Oxford Knee Score (OKS) at baseline, 6 and 12 months 2. Pain description is assessed using PainDETECT and Douleur Neuropathique 4 (DN-4) at baseline, 6 and 12 months 3. Emotional aspects of pain are measured using the Hospital Anxiety and Depression Scale (HADs), Pain Catastrophizing Scale (PCS), and Possible Solutions to Pain Questionnaire (PaSol) at baseline, 6 and 12 months 4. Use of pain medications is measured using Resource use questions at baseline, 6 and 12 months 5. Improvement and satisfaction with pain relief is measured using the Self-Administered Patient Satisfaction Scale (single-item question on comparison of pain to pre-operative pain) at baseline, 6 and 12 months 6. Temporal aspects of pain are measured using Single-item questions on pain frequency during past 24 hours and 4 weeks, at baseline, 6 and 12 months 7. Capability is measured using the ICECAP-A at baseline, 6 and 12 months 8. Health-related quality of life is measured using EQ-5D-5L and Short Form-12 (SF-12) at baseline, 6 and 12 months 9. Pain elsewhere is assessed using a body diagram to assess chronic widespread pain at baseline, 6 and 12 months 10. Resource use is measured as use of health services including primary, secondary and tertiary care; use of personal social services; additional costs (travel, lost income, home modifications) using follow-up trial questionnaires at 12 months. Resource use data including inpatient stays and outpatient visits for all patients will be obtained from hospital electronic systems. If this is not possible, they will be extracted from hospital records and recorded on standardised proformas. | — |
