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

Experimental: Ropivacaine + femoral block
After the surgery is proceeded and after the closure of the joint capsule, 20 cc of ropivacaine 0.5% is inserted intra-articular through a catheter.
