The purpose of this study was to evaluate the effect of preoperative opioid use on opioid prescriptions, refills, and clinical outcomes after total knee arthroplasty (TKA). ⋯ Preoperative opioid users were discharged with less opioids, required more refills, were more likely to remain on opioids, and required more manipulations under anesthesia than opioid-naive patients. These risks extended to preoperative tramadol users.

The state of Maryland was granted a waiver by the Center for Medicare and Medicaid Services to implement a Global Budget Revenue (GBR) reimbursement model. This study aims to compare (1) costs of inpatient hospital stays; (2) postacute care costs; (3) lengths of stay (LOS); and (4) discharge disposition who underwent primary total hip arthroplasty at a single Maryland-based orthopedic institution before and after the implementation of GBR. ⋯ There was a significant decrease in inpatient costs ($26,575 vs $23,712), an increase in mean home health costs ($627 vs 1608), and a decrease in mean durable medical equipment costs ($604 vs $82) and LOS (2.92 days vs 2.33 days). There was an increase in discharge to home rates (72.3% vs 78.9%) and a decrease in discharge to acute rehabilitation (4.3% vs 1.8%) CONCLUSION: Under the GBR model, our institution experienced significant cost savings during the inpatient and postacute care episodes. Thus, GBR may serve as a viable solution to reducing costs to Medicare for high-volume arthroplasty institutions with a large Medicare population. Multicentered studies are needed to verify our results.

The aim of this study is to investigate differences in implant requirement, outcomes, and re-revision when total knee arthroplasty (TKA) was performed following unicompartmental knee arthroplasties (UKAs) with metal-backed (MB) compared to all-polyethylene (AP) tibial components. ⋯ MB UKA implants increase the chances of a complex revision requiring tibial stems and cruciate substitution but reduce the chances of early revision compared to AP UKA which often fail early with pain.

Opioids are a mainstay in perioperative pain management among patients undergoing total knee arthroplasty (TKA). However, patterns in opioid use before and after TKA have not been well-studied. The objectives of this study are to characterize prescribing trends preoperatively and postoperatively and identify risk factors for chronic postoperative opioid use. ⋯ The greatest risk factors for chronic postoperative opioid use were preoperative use, younger age, female gender, greater length of stay, and worse health status. Although the use of opioids continues to grow significantly preoperatively and postoperatively, chronic opioid use post-TKA has remained clinically unchanged.

Unicompartmental knee arthroplasty (UKA) is touted as a more conservative, bone- and tissue-sparing procedure than total knee arthroplasty (TKA). Similarly, revision of UKA to TKA is generally a simpler procedure than revision of TKA to TKA and can be accomplished with primary TKA components in most cases. The purpose of this study was to review a consecutive series of patients undergoing revision of failed UKA to TKA to determine if etiology is similar to that reported in recent literature and evaluate if the results align more with primary TKA vs revision of TKA to TKA. ⋯ Compared to published individual institution and national registry data, re-revision rates of failed UKA are equivalent to revision rates of primary TKA and substantially better than re-revision rates of revision TKA. These data should be used to counsel patients undergoing revision UKA to TKA.
