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.
