Risk of Opioid-Related Adverse Events After Primary and Revision Total Knee Arthroplasty.

Postoperative analgesia after primary total knee arthroplasty (TKA) and revision knee arthroplasty (RKA) can be reliant on the use of opioids and may lead to opioid-related adverse events (ORAEs). This study evaluated the risk of ORAEs following TKA and RKA using the 5% Medicare claims (2010-2013) database. There were 41,702 TKA and 3817 RKA patients who met the inclusion criteria.

Quantifying the Risk of Analgesic-Related Adverse Events After Knee Arthroscopy.

Opioids are frequently used as part of multimodal pain management protocols for knee arthroscopy; however, their use may be associated with opioid-related adverse events. The purpose of this study was to evaluate the risk of potential analgesic-related complications after knee arthroscopy using a nationally representative database. Using 2010\endash 2012 Medicare claims data, patients undergoing knee arthroscopy procedures (including ligament repair, meniscectomy, and chondroplasty) were identified.
