Total Knee Arthroplasty Utilizing Adductor Canal Block: Effect on Quadriceps Sparing

NCT02081911 · Status: TERMINATED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 33

Last updated 2016-02-02

No results posted yet for this study

Summary

The purpose of this study is to investigate whether there is quantitative motor-sparing of the quadriceps muscles following adductor canal nerve block versus femoral nerve block. Patients will be randomly placed into one of three treatment groups: 1) Femoral nerve block, 2) Adductor canal nerve block - low volume, or 3) Adductor canal nerve block - high volume. Quadriceps function will be assessed in the operating room using a skin patch and electrical stimulation. Follow up visits with the patients will continue over the course of 2 days during patient's stay at the hospital. A total of 60 patients will be enrolled for the study.

Conditions

  • Osteoarthritis (Knee)

Interventions

PROCEDURE

High Volume Adductor Canal Block

Adductor canal block performed in the distal thigh (1/3 of the total distance between the superior border of the patella and the femoral crease, cephalad to the patella) utilizing an injectate volume of 30 mL 0.25% bupivacaine/ epinephrine

PROCEDURE

Low Volume Adductor Canal Block

Adductor canal block performed in the distal thigh (1/3 of the total distance between the superior border of the patella and the femoral crease, cephalad to the patella) utilizing an injectate volume of of 10 mL 0.75% bupivacaine/ epinephrine

PROCEDURE

Femoral Nerve Block

Femoral nerve block with 10 mL 0.75 % bupivacaine/epinephrine
