Tibial Nerve Versus Sciatic Nerve Block

Selective Tibial Nerve Block vs Popliteal Sciatic Nerve Block in Patients Having Total Knee Arthroplasty

The purpose of this study is to analyse the ability to selectively block the posterior tibial nerve sparing the function of the common peritoneal nerve. To assess the efficacy of blocking the posterior tibial nerve will give the same post-operative pain relief after total knee surgery compared to a sciatic nerve block.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
To assess if selectively blocking only the tibial nerve component of the sciatic nerve will prevent foot drop.	Measure frequency of foot drop in two groups and compare results.	Upon emergence from general anesthesia and up to 48 hours in the recovery room.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
To assess if levels of pain and analgesic requirements are similar between the two groups.	Administer pain scale and monitor use of analgesics to compare levels two groups.	24 hours after total knee replacement surgery.
