Study Summary
The purpose of this study is to learn if using an Interspace between the Popliteal Artery and Capsule of the Knee (iPACK) injection technique (also called a "nerve block") that numbs the nerves going to the back part of the knee to aid in physical therapy after surgery. The iPACK technique uses a numbing solution (local anesthetics) that is injected behind the knee to reduce pain and to help straighten the knee. This block may affect movement in the leg and make the legs weak, but thing is rare. A few institutions use the iPACK block for patients having total knee replacements, with the hope of providing good pain relief combined with improved mobility after surgery.
Primary Outcome
Ability to hyperextend the knee after surgery
Interventions
- DRUG Saline
- DRUG Ropivacaine
- PROCEDURE Interspace Between the Popliteal Artery and Capsule of the Knee (iPACK) Block
