Summary

This is a prospective, randomized control trial to compare SPANK block combined with adductor canal block to adductor canal block alone in treatment of post-operative pain after total knee arthroplasty. The primary outcome is pain control, which will be measured throughout the post-operative course using morphine equivalents of opioid analgesics used during the first 24 hours after surgery. Secondary outcomes include pain scores recorded at 4, 8, 12, 16, 20, and 24 hours post-operatively, cumulative pain score, incidence of post-operative nausea and vomiting, and extent of motor blockade. The study will aid in answering the question of whether SPANK block is an effective adjunct in preventing pain and decreasing opioid requirement after TKA.

Conditions

• Osteo Arthritis Knee
• Pain, Postoperative
• Pain, Acute

Interventions

Type	Name	Description
PROCEDURE	SPANK Block (Sensory Posterior Articular Nerves of the Knee)	Injection of local anesthetic into the tissues on the posterior aspect of the knee to provide sensory blockade of the articular nerves of the knee.
PROCEDURE	Adductor Canal Block	Injection of local anesthetic into the inner thigh under ultrasound guidance to provide sensory blockade to the anterior aspect of the knee
DRUG	Ropivacaine Hcl 0.5% Inj Vil 30Ml	Amide local anesthetic, this concentration is commonly used to achieve surgical level anesthesia. The drug itself is not being studied and the same concentration will be used in all participants.
DEVICE	Pajunk sonoplex stim needle	Echogenic needle used for ultrasound guided nerve blockade.
