4 key points on complication risk for outpatient total joint replacements

A new study published in the Journal of Bone and Joint Surgery examined outpatient total knee replacement risk for complication.


The study authors gathered data from the PearlDriver Patient Record Database Humana subset to examine total knee arthroplasty patients who underwent inpatient and outpatient procedures from 2007 to 2015. The study included 4,391 outpatient total knee arthroplasties and 128,951 inpatient total knee arthroplasties.


Study authors found:


1. The volume of outpatient total knee arthroplasties increased over time.


2. Outpatient total knee replacements were more likely to include tibial and/or femoral component revision within one year of their primary procedure for a variety of reasons, including:


• Noninfectious causes
• Prosthesis explanation
• Irrigation and debridement
• Stiffens that required additional manipulation under anesthesia


3. The outpatient procedures were often associated with complications postoperatively, including deep vein thrombosis or acute renal failure, according to the report.


4. Study authors concluded, "With the potential to maximize arthroplasty costs among healthy patients, outpatient TKA is an increasingly popular option. Nationwide data from a private insurance database demonstrated a higher risk of perioperative surgical and medical complications including component failure, surgical site infection, knee stiffness and deep vein thrombosis."
