Design outcomes

Primary

Measure	Time frame
As this is a feasibility RCT there were no primary outcome measures as such. 1. Rate of participant uptake 2. Reasons for non-attendance at classes 3. Patient satisfaction with the classes 4. Timing and suitability of the exercises	—

Secondary

Measure	Time frame
Patient-reported outcomes including: 1. KOOS = Knee Injury and Osteoarthritis Outcome Score – pre-op, 2 weeks, 3 months and 6 months post-op 2. LEFS = lower extremity functional scale - 2 weeks, 3 months and 6 months post-op 3. ABC scale = activities-specific balance confidence scale - pre-op, 2 weeks, 3 months and 6 months post-op 4. Pain VAS = pain visual analogue scale - pre-op, 2 weeks, 3 months and 6 months post-op 5. UCLA = UCLA activity score - pre-op, 2 weeks, 3 months and 6 months post-op 6. SER = self-efficacy for rehabilitation - pre-op, 2 weeks, 3 months and 6 months post-op 7. Ab-IAP = Aberdeen Measures of Impairment, Activity Limitation and Participation Restriction - pre-op, 2 weeks, 3 months and 6 months post-op 8.
