Summary

Adductor canal blocks (ACB) have been recommended in total knee arthroplasty (TKA) to provide better control of post-operative pain, facilitate early ambulation, and reduce length of stay in the hospital. ACB is typically done before surgery by an anesthesiologist, which may increase time per case, cost, and requires the specialized skills of an anesthesiologist trained in regional anesthesia. Recent studies have suggested that surgeons can safely and reliably administer the adductor canal blocks (sACB) during surgery. However, there is currently very limited data on the clinical efficacy of such sACBs, and no studies assessing this technique in the context TKA that are discharged the same day. As such, this randomized control trial (RCT) is being done to compare sACBs to conventional anesthesiologist-performed adductor canal blocks (aACB).

Conditions

• Knee Osteoarthritis
• Knee Arthritis
• Knee Pain Chronic
• Anesthesia

Interventions

Type	Name	Description
PROCEDURE	aACB	The patient will undergo a pre-operative single-shot, ultrasound-guided ACB performed by an anaesthesiologist skilled in regional anaesthesia techniques. The ACB will be performed in a dedicated block room, immediately prior to administration of a spinal anaesthetic.
PROCEDURE	sACB	The patient will undergo an intraoperative single-shot ACB performed by the treating surgeon following placement of the TKA components.
