Randomized Controlled Trial Multicenter Study
Local Infiltration Analgesia With Liposomal Bupivacaine Improves Early Outcomes After Total Knee Arthroplasty: 24-Hour Data From the PILLAR Study.
Enhanced postoperative care pathways have shifted total knee arthroplasty (TKA) to outpatient and short-stay settings, placing greater emphasis on predischarge outcomes. In this study, we report prespecified secondary and tertiary end points of the PILLAR study within 24 hours after TKA in patients receiving local infiltration analgesia (LIA) with or without liposomal bupivacaine (LB). ⋯ LIA with LB 266 mg plus bupivacaine HCl significantly reduced opioid requirements and pain intensity and significantly improved discharge readiness and satisfaction 0-24 hours after TKA compared with bupivacaine HCl alone. These findings support the use of LIA with LB for TKA when early discharge is the goal.

Anterior knee pain (AKP) remains a complex issue affecting patient satisfaction after total knee arthroplasty. Several radiographic parameters have been shown to be causative factors with various designs. The aim of this study is to evaluate the known radiographic parameters of AKP and clinical outcomes (ie, AKP) in the setting of a modern prosthesis with an anatomic patella button. ⋯ We found that a patellar resection angle correlated with the incidence of AKP and painless noise at 2-year follow-up. We failed to find any correlation with patellofemoral overstuffing, patellar displacement, or patellar tilt with clinical outcomes. We recommend the use of 3 Merchant views to fully evaluate the patellofemoral joint.

In the United States, opioids are commonly prescribed to treat knee pain after total knee arthroplasty (TKA). While surgery leads to decreased pain in most patients, a sizable minority continue to experience severe pain and consume opioids chronically after TKA. We sought to determine the population-level effect of TKA on opioid consumption by detailing the pattern of opioid prescriptions before and after surgery. ⋯ Retrospective cohort study.

Rheumatoid arthritis patients are at increased risk for periprosthetic joint infection after arthroplasty. The reason is multifactorial. Nasal colonization with Staphylococcus aureus is a modifiable risk factor; carriage rates in RA patients are unknown. The goal of this study is to determine the S aureus nasal carriage rates of RA patients on biologics, RA patients on traditional disease-modifying anti-rheumatic drugs (DMARDs), and osteoarthritis. ⋯ S aureus colonization risk was increased for RA on biologics compared to RA not on biologics and OA. Nasal S aureus carriage increases the risk of surgical site infection; this modifiable risk factor should be addressed prior to total joint arthroplasty for this higher risk patient group.

Spin is a specific type of reporting bias that misrepresents data and results within randomized controlled trials (RCTs). Because spin may provide a surgeon with an inaccurate representation of trial results, thus misconstruing the surgeons' interpretation thereof and possibly negatively affecting patient care, it is important that spin is identified within publications. The primary goal of our study was to determine the prevalence of spin found within the abstracts of lower extremity joint trials. ⋯ Our study found that a significant number of lower extremity joint RCTs contain one or more form of spin in either their abstract results, conclusions, or both. In addition, our investigation revealed that a sizable portion of these lower extremity orthopedic joint RCTs are not registered or do not report their registration, and funding sources are also underreported.
