Study Arms:
- Motor Sparing Nerve Block (Type: ACTIVE_COMPARATOR): Motor sparing knee block (60mL of 0.5% ropivacaine with 10 mg Morphine, 30 mg Ketorolac and 150 mcg of epinephrine as the initial bolus) initiated in the preoperative period in the block room as per the standard practice and continued until discharge. Spinal anesthetic with 15 mg of hyperbaric bupivacaine. Patients will be connected to an Ambit infusion pump in the postoperative period set to deliver ropivacaine 0.2% at a basal infusion rate of 7 mL/Hr with patient controlled boluses of 5mL every hour for breakthrough pain. Patients will be discharged home following removal of the anaesthetic catheter and fulfilling criteria for discharge.
- Peri-Articular Catheters (Type: EXPERIMENTAL): 3 peri-articular catheters inserted at the end of surgery followed by peri-articular infiltration with ropivacaine 0.2% and wound infusions will be continued until discharge using elastomeric devices. Spinal anesthetic with 15 mg of hyperbaric bupivacaine. Patients will be discharged home following removal of the anaesthetic catheter and fulfilling criteria for discharge.

Based on this trial design, predict the completion outcome and termination type (if applicable).
