Femoral Block With or Without Ropivacaine for Analgesia After Total Knee Replacement (TKR) (TKR)

This study has been completed.

Hopital de l'Enfant-Jesus Identifier:
First received: May 28, 2009
Last updated: February 25, 2011
Last verified: May 2009

Total knee replacement is a painful procedure. Many solutions have been proposed to diminish the post-operative doses of narcotics, including nerve blocks.

The purpose of the study is to compare if the adjunction of intra-articular ropivacaine to a femoral block is more effective on narcotics consumption than the block alone after TKR.

Condition Intervention Phase
Total Knee Replacement Drug: Ropivacaine Phase 1 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized Trial Comparing the Efficacy on Post-operative Analgesia of Intra-articular Ropivacaine Added to a Femoral Block After Total Knee Replacement
