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

A Randomized Trial Comparing the Efficacy on Post-operative Analgesia of Intra-articular Ropivacaine Added to a Femoral Block After Total Knee Replacement

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.

Inclusion Criteria:

• Primary total knee replacement
• Age > 18 years old
• Accept the study

Exclusion Criteria:

• Revision surgery
• Use of anticoagulants drugs
• Neurologic disorder
