Brief Summary:

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.

Arm Intervention/treatment
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.
Drug: Ropivacaine
0.5% intra-articular ropivacaïne (20cc)

Primary Outcome Measures :
  1. Narcotic consumption per 24 hours after surgery (mg/kg) [ Time Frame: 48 hours ]

Secondary Outcome Measures :
  1. VAS score at 24 hours [ Time Frame: 48 hours ]
