Summary

An observational study of the effect of femoral nerve block in addition to an adductor canal block for pain following total knee arthroplasty.

Detailed description

Subjects undergoing total knee arthroplasty will receive a preoperative adductor canal block with continuous catheter. Following a standardized general anesthetic for the procedure, subjects will be asked to rate their pain using the NRS-11 pain scale in the recovery room. Once the pain is reported at a 5/10 or above, a femoral nerve block will be performed using either 2% chloroprocaine or saline placebo (randomized). Pain scores are then evaluated over the next 30 minutes by a blinded investigator to determine if the femoral block adds any additional analgesic benefit over an adductor canal block.

Conditions

• Osteo Arthritis Knee

Interventions

Type	Name	Description
PROCEDURE	Active comparator: chloroprocaine	15 ml of 2% chloroprocaine was placed under ultrasound guidance adjacent to the femoral nerve in the operative limb.
PROCEDURE	Sham comparator: saline	15 ml of normal saline was placed under ultrasound guidance adjacent to the femoral nerve in the operative limb.
