Comparison of Analgesic Efficiency Between IPACK Block and Surgical Infiltration After Total Knee Arthroplasty

Comparison of Analgesic Efficiency Between IPACK Block (Interspace Between the Popliteal Artery and the Capsule of the Posterior Knee) and Surgical Infiltration After Total Knee Arthroplasty

The purpose of this retrospective study is to compare the analgesic efficiency of IPACK block (Interspace between the Popliteal Artery and the Capsule of the posterior Knee) with surgical infiltration after total knee arthroplasty. The main objective is to compare cumulative morphine consumption the first 24 hours after surgery. The secondary objectives are to compare pain scores, types and amounts of other analgesics needed during the first 24 hours after surgery.

After patient agreement, data will be collected on patient records and will be compared into 2 groups.

Data will be :

• cumulative consumption of morphine during the first 24 hours after surgery
• pain scores during the first 24 hours after surgery
• amount of analgesics during the first 24 hours after surgery
• maximal pain score during the first 24 hours after surgery

Inclusion criteria:

- All adults patients after a total knee arthroplasty since november 2015

Exclusion criteria:

- Child, non primitive surgery
