Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are two of the most prevalent procedures performed on the aging population. The invasive nature of these procedures is associated with a substantial amount of post op opiate consumption. In order to reduce opioid consumption in this patient population, a multimodal pain control pathway (MP) was created at OHSU using input from pharmacy, nursing and surgery. The aim of this study is to evaluate the effectiveness of this pain control pathway in reducing post-operative opioid consumption.
