A Comparison of Proximal Versus Distal Continuous Adductor Canal Blocks After Total Knee Arthroplasty

This study is designed to evaluate pain control of continuous adductor canal blocks placed
proximally versus distally within the canal. The investigators hypothesize that there will
be similar pain control between both groups.

This study is a non-inferiority trial designed to determine whether placement of a
continuous block within the adductor canal has a substantial impact on pain following total
knee arthroplasty. Our primary outcome to determine this difference will be opioid
consumption within the first day following surgery. Secondary outcomes will include: pain
scores, quadriceps strength, and distance ambulated during physical therapy.
