Tibial Nerve Versus Sciatic Nerve Block

An interventional study of Selective Tibial Nerve block and Sciatic Nerve Block in Post Operative Analgesia, sponsored by Trinity Health Of New England. Completed at 1 site in United States. Open to participants aged 18 Years to 85 Years. Per ClinicalTrials.gov, last updated 2015-03-18.

Sponsored by Trinity Health Of New England · Not applicable, Interventional, and Treatment

Phase: Not applicable
Study type: Interventional
Enrollment: 80
Allocation: Randomized
Ages: 18 Years to 85 Years
Sex: All

Study 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.

What researchers measure

Primary outcomes

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.
Time frame: Upon emergence from general anesthesia and up to 48 hours in the recovery room.

Secondary outcomes

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.
Time frame: 24 hours after total knee replacement surgery.

The record gives a start of Mar 2009, a primary completion of Mar 2009 and a completion of Dec 2010. It does not say whether these dates are actual or estimated.

How these figures are worked out, and which studies are left out of them.

What these dates mean

Start.: When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.: When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.: When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.: Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.

No changes since tracking began. The registry record was last updated on Mar 18, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
