Primary Outcome Measures

Name	Time	Method
Patient reported pain scores using the 0-10 Visual Analogue Scale for Pain (VAS Pain) [First 6 weeks after TKR surgery. The frequency of assessment will be daily post surgery for 3-5 days and then weekly until the 6 week post-operative mark. ];Opioid (morphine) use. A researcher will record the opioid intake from the previous 24 hours at the same time each day for the first 3-5 days after surgery. This will be documented in the patients medication chart. Morphine equivalent dosing will be calculated to determine the cumulative intake of opioid drug use for the previous 24 hours. Participants will also be asked to record their opioid intake in a pain medication table each week after surgery until the 6 week post-operative mark and this information will be recorded in the patients electronic file.
