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.

Total Opiate pain medication
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
Time frame: The total amount of opiate pain medication will be recorded at 6 hour intervals for 48 hours after surgery.
Patient satisfaction with pain control
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.
Time frame: We will look at the secondary outcome measure beginning every six hours for 48 hours after surgery
