BACKGROUND:The opioid epidemic is a health crisis in the United States. Within orthopedic surgery, opioid misuse and incautious prescription remains a concern. In the last several years, there has been a growing interest and public effort toward reducing opioid use in total joint arthroplasty (TJA) in response to the opioid epidemic in the United States. We aim to review opioid-limiting practices, policies, and legislations that are implemented at the state level and nationally that are relevant to TJA, as well as evaluate studies that measure the efficacy of these policies in the management of patients undergoing TJA. METHODS:Two independent reviewers conducted a systematic review of national and state level opioid-limiting policies implemented in the United States and their effects on opioid prescription, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA). RESULTS:We identified 3 national bills and 9 policies set forth by national organizations that imposed limits on opioid prescription. Opioid-reducing legislation was also identified in 24 states, with the majority specifying a 7-day limit on initial opioid prescription for acute pain management. Six research studies evaluating the impact of opioid-restricting policies on postoperative opioid prescription for TJA patients were found. Three studies assessed legislation at the state level while the others were institution-based guidelines. Overall, these studies demonstrated a significant decrease in mean morphine milligram equivalents of initial opioid prescription after implementing the policies. CONCLUSION:Recent opioid-restricting legislation is effective in decreasing postoperative opioid prescriptions following TJA.

There is limited literature reporting the oral pathogen Parvimonas micra as the causative organism of periprosthetic joint infection. Previous reports demonstrate septic arthritis in native or prosthetic joints due to P. micra in elderly or immunocompromised patients associated with tooth abscess and periodontal disease. Our case report is unique because it describes a healthy individual with recurrent gingivitis developing periprosthetic joint infection after total knee arthroplasty as the result of isolated P. micra. Her clinical symptom presented early and manifested as progressive stiffness only. Timely aspiration resulted in early diagnosis, but the patient still underwent 2-stage revision with a more constrained implant. To prevent the risk of infection by oral pathogens such as P. micra, dental history should be thoroughly investigated, and any lingering periodontal infection should be addressed before any arthroplasty operation.
