Brief Summary:
The purpose of this study is to evaluate the efficacy of two methods of administering an adductor canal block (ACB) following total knee arthroplasty (TKA); intraoperative surgeon performed intra-articular adductor canal block (IACB) and anesthesiologist ultrasound guided ADC in the post-anesthesia recovery unit (PACU).

Arm Intervention/treatment
Placebo Comparator: Control
Anesthesiologist preforms ultrasound guided adductor canal block post-operatively
Drug: Ropivacaine
For primary TKA, Ropivacaine is used in both arms, either performed intra-operatively by surgeon or post-operatively (ultrasound guided) by anesthesiologist.

Experimental: Intervention
Surgeon preforms inter-operative adductor canal block
Drug: Ropivacaine
For primary TKA, Ropivacaine is used in both arms, either performed intra-operatively by surgeon or post-operatively (ultrasound guided) by anesthesiologist.

Primary Outcome Measures :
  1. Change in visual analog scale pain score [ Time Frame: Up to 6 weeks post-surgery ]
    The primary end point is the patients' reported visual analogue pain score (VAS). 0-100mm scale

Secondary Outcome Measures :
  1. Change in range of motion [ Time Frame: up to 6 weeks post-surgery ]
    Range of motion

  2. Change in timed up and go [ Time Frame: up to 6 weeks post-surgery ]
    Timed up and go

  3. Change in daily opioid consumption [ Time Frame: up to 6 weeks post-surgery ]
    daily opioid consumption
