Brief summary
The purpose of this study is that an adductor canal nerve block (putting numbing medicine near the nerve) has been shown to produce excellent pain relief with less pain medication use after knee replacement surgery.The investigators will be comparing the amount of pain relief following knee replacement surgery when you have a nerve block in place. There will be approximately 66 subjects participating in this study. After surgery subjects will receive numbing medication every 6 hours for 48 hours. Subjects will also receive a morphine PCA (patient controlled analgesia) after surgery and pain medication by mouth every 4 hours around the clock with the option to receive more pain medication if needed. Subjects will participate in the study up to 3 days.
Interventions
DRUGMorphine PCA started at the end of surgery, 1 Percocet 1/325mg every 4 hours; may receive a second Percocet if needed.
DRUGFor the 30ml ropivacaine the intervention would be the subject can request extra pain medication which would be Percocet and/or morphine PCA.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total Opiate pain medication | The total amount of opiate pain medication will be recorded at 6 hour intervals for 48 hours after surgery. | At the end of the 48 hours period the total opiate pain medication taken will be collected and used for comparison as our primary outcome |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient satisfaction with pain control | We will look at the secondary outcome measure beginning every six hours for 48 hours after surgery | Secondary outcome measures will include demographic characteristics, pain scores, medication administration,patient satisfaction with pain control and any complications that may have arisen. We will also record the location of the adductor canal catheter on the final bolus dose. |
