Design outcomes

Primary

MeasureTime frame
Pain will be measured using the Numerical Rating Score of pain over a 48 hour period after surgery collected at 8am, 12pm, 5pm and 10pm on each day.

Secondary

MeasureTime frame
1. Opioid use over the first 48 hours after surgery is recorded by blind assessors throughout each patient's hospital stay 2. Time to mobilisation after surgery will be determined by recording walking distance, ability to complete leg lifts and range of motion during physiotherapy 4 hours post-surgery, 1 and 2 days post-surgery
