Instability following total knee arthroplasty is a leading cause of failure and is often treated with component revision. The goal of this study was to determine if isolated tibial polyethylene insert exchange (ITPIE) to a higher-level constraint would afford similar outcomes to component revision in the properly selected patient. We retrospectively evaluated 176 consecutive patients between 2016–2017 who were revised for symptomatic instability at a single institution. Demographic information and level of constraint preoperatively and postoperatively were documented. Radiographic parameters were also recorded for patients undergoing ITPIE. Outcome measures included all cause re-revision rates as well as patient reported outcome measures (PROMs) obtained preoperatively and at minimum 1-yr follow up. Descriptive analysis including sample t-test and chi square test were performed with statistical significance set at p <0.05.Introduction

Despite evidence-based recommendations opioids and benzodiazepines are commonly prescribed to treat osteoarthritis. This study aims to quantify the prevalence of opioid and benzodiazepine prescriptions given for the primary diagnosis of osteoarthritis across a large healthcare system. Additionally, we aim to characterize risk factors for drug misuse, abuse, and diversion. We conducted a descriptive analysis of adult patient encounters with a primary diagnosis of osteoarthritis during a one-year time period from Jan –Dec 2016 at a large, healthcare system. Demographic data, prescription data, patient-specific prescription drug use risk criteria were collected. Descriptive analysis was conducted to characterize the population of arthritis patients who received prescription opioids. The rate of controlled substance prescribing was calculated for the population as a whole and among subgroups (age, facility type, and patient risk profile).Introduction
