Design outcomes

Primary

Measure	Time frame
Physical activity, as measured using an Actiwatch device (Philips Respironics, Murrysville, PA, USA) from baseline (pre-surgery) to 8 weeks post-surgery	—

Secondary

Measure	Time frame
At baseline and 8-weeks post-surgery (unless otherwise stated): 1. Physical performance (PBOMs): 40m paced walk test, 30s sit-to-stand, 9 step stair-climb 2. Pain and function daily living subscales from Knee Injury and Osteoarthritis Outcome Score (KOOS) 3. Analgesic use measured using self report 4. Pain levels on activity measured using a numerical rating scale at baseline, and each week post-surgery until 8 weeks 5. C-reactive protein (CRP) measured using ... from baseline to one day following surgery (or at discharge if discharged on day of surgery) 6. Patient expectations (HSS Knee Replacement Expectation Survey) at baseline 7. Anxiety and depression measured using the Hospital Anxiety and Depression Score (HADS) at baseline 8. Pain catastrophizing measured using the Pain Catastrophizing Scale (PCS) at baseline 9. Frailty measured using the Edmonton Frail Scale at baseline 10. Number of falls in the past three months measured using self report at baseline 11. Classification of osteoarthritis measured using the Kellgren and Lawrence system at baseline	—
