Effect of making skin incision with electrocautery on positive Cutibacterium acnes culture rates in shoulder arthroplasty: a prospective randomized clinical trial.

Background: Cutibacterium acnes remains the most commonly detected organism in shoulder arthroplasty. C acnes infection is thought to occur during shoulder arthroplasty through contamination of the surgical field with C acnes from the incised dermis. The purpose of this study was to examine whether using electrocautery for making skin incisions would decrease C acnes culture rates at the incised dermis compared to using scalpels during shoulder arthroplasty.

Local Infiltration Analgesia Versus Interscalene Block for Pain Management Following Shoulder Arthroplasty: A Prospective Randomized Clinical Trial.

Background: While providing effective analgesia following shoulder arthroplasty, an interscalene block has known complications. Local infiltration analgesia (LIA) using ropivacaine has been successfully employed in other joint arthroplasties, but its efficacy in shoulder arthroplasty has not been studied extensively. The purpose of this study was to compare pain and opioid consumption between LIA and an interscalene block following shoulder arthroplasty.
