Obturator Nerve Block With Femoral and Sciatic Block

Is an Obturator Nerve Block Required for Every Patient Having Total Knee Arthroplasty With Femoral and Sciatic Nerve Block?

The purpose of this study is to evaluate how many patients require the addition of the obturator nerve block in the recovery room after the total knee surgery. Also to study the efficacy of blocking the obturator nerve in controlling their knee pain.
