Dispensing Medication If the patient approves to participate in the study, they will receive the allotted post-operative medication at time of discharge prescriptions for their postoperative medications as above at their preoperative visit. In addition, patients will also receive a sealed envelope with a prescription for a back-up supply of pain medication (10 pills of oxycodone 5mg). They will be instructed to fill these only if they run out of the previous supply and are still requiring stronger pain medication. Because of the way the prescription will be written (with instructions to the pharmacy not to fill before the date of post-operative day 2), they cannot automatically fill the same day as discharge (post-operative day 1) and this prescription is only valid for two weeks after this date. They will be instructed that if they require more pain medication than this, they will need to be seen. Patients will be provided with a daily pain and activity diary and medication log. At their 6-week postoperative visit, patients will bring in this diary as well as any remaining opiate medication and/or the sealed envelope containing the back-up prescription.
