Post Operative Analgesia
Conditions
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To assess if selectively blocking only the tibial nerve component of the sciatic nerve will prevent foot drop. | Upon emergence from general anesthesia and up to 48 hours in the recovery room. | Measure frequency of foot drop in two groups and compare results. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To assess if levels of pain and analgesic requirements are similar between the two groups. | 24 hours after total knee replacement surgery. | Administer pain scale and monitor use of analgesics to compare levels two groups. |
