Continuous Adductor Canal Nerve Catheter
Ultrasound guided femoral nerve block with 20cc of 2% mepivacaine \<20 minutes prior to in room time. Patients then undergo general anesthesia under the care of the attending anesthesiologist assigned to the patient. Induction with propofol bolus and placement of laryngeal mask airway. Intraoperative opioid limited to no \> 150mcg of fentanyl. Completion of procedure, dressing and LMA revoved with patients transferred to PACU. Once adequately awake and alert this group will receive ultrasound guided adductor canal continuous nerve catheter using normal saline bolus followed by 1/8% bupivacaine infusion through catheter at 8cc/h.
Long Acting Single Bolus Adductor Canal Nerve Block
Ultrasound guided femoral nerve block with 20cc of 2% mepivacaine \<20 minutes prior to in room time. Patients then undergo general anesthesia under the care of the attending anesthesiologist assigned to the patient. Induction will include a propofol bolus and placement of laryngeal mask airway. Intraoperative opioid should be limited to no \> 150mcg of fentanyl. Upon completion of wound closure, appropriate dressing placement, emergence from anesthesia and removal of LMA, patients to be taken to PACU. Once adequately awake and alert this group will receive ultrasound guided adductor canal nerve block with 10cc of 0.5% ropivacaine and 2 mg dexamethasone (0. 5cc), keeping total injectate at 10.5cc.

PRIMARY outcome

Timeframe: Post Operative Day 1

Population: Data was unavailable for 1 participant in both groups.

Quadriceps strength on POD 1 of preoperative femoral nerve block plus postoperative continuous adductor canal nerve catheter compared to preoperative femoral nerve block plus postoperative saphenous nerve block using Straight Leg Raise Tests, 0-5/5 scale, and knee extension, 0-5/5 scale. On both scales (straight leg raise test and knee extension) 0 indicates the minimum value (low muscle contraction/no movement) and 5 indicates the maximum (normal muscle contraction /pt holds position against pressure).

Timeframe: Post Operative Week 6

Population: Data was unavailable for 1 participant in each group.

Quadriceps strength on POD week 6- pts receiving (1) long-acting single bolus adductor canal nerve block comparied to (2) continuous adductor canal nerve catheter using Straight Leg Raise Tests, 0-5/5 scale, and knee extension, 0-5/5 scale. On both scales (straight leg raise test and knee extension) 0 indicates the minimum value (low muscle contraction/no movement) and 5 indicates the maximum (normal muscle contraction /pt holds position against pressure).

n=34 participants at risk
Ultrasound guided femoral nerve block with 20cc of 2% mepivacaine \<20 minutes prior to in room time. Intraoperative patients will undergo initiation of general anesthesia under the care of the attending anesthesiologist assigned to the patient. Induction will include a propofol bolus and placement of laryngeal mask airway. Intraoperative opioid should be limited to no more than 150mcg of fentanyl. Upon completion of wound closure, appropriate dressing placement, emergence from anesthesia and removal of LMA, patients to be taken to PACU. Once adequately awake and alert this group will receive ultrasound guided adductor canal continuous nerve catheter using normal saline bolus followed by 1/8% bupivacaine infusion through catheter at 8cc/h. Mepivacaine: 20cc of 2% mepivacaine \<20 minutes prior to in room time. adductor canal continuous nerve catheter: Placement of ultrasound guided adductor canal continuous nerve catheter Normal Saline as bolus followed by bupivacaine: normal
