Wound Irrigation Comparative Effectiveness Study

Cutibacterium Acnes Removal by Wound Irrigation With Normal Saline Versus Irrisept During Total Shoulder Arthroplasty

The primary objective of this study is to compare the presence of C acnes in bacteriologic cultures taken from participant samples of subcutaneous and deep tissue prior to deep surgical irrigation using either Normal Saline Irrigation (Group 1) or Irrisept Irrigation (Group 2). Secondary objectives are evaluation of patient reported outcome measures and range of motion in relation to C acnes presence among subjects in the two groups.
