Accurate sizing is critical for the overall success of a total knee arthroplasty (TKA). This study's primary purpose was to investigate the ability to predict the tibial and femoral component size in a single implant system from patient demographics and anthropometric data. A secondary goal was to compare the predicted tibial and femoral component sizes from our statistical model with a previously validated electronic application used to predict the implant size. ⋯ Our novel templating model may improve operative efficiency for a single TKA system. Our findings have a high concordance with a widely available electronic application used to predict implant sizes for a variety of TKA systems.

The impact of femoral nerve blocks (FNBs) during primary total knee arthroplasty (TKA) on clinical outcomes and pain management remains unclear. The present research investigates the impact that continuous and single-shot FNBs during TKA have on postoperative opioid claims and short-term clinical outcomes. ⋯ FNBs during TKA place patients at a significantly higher risk of falls, readmissions, and systemic complications in the short term. The risk of readmission and systemic complications was higher for continuous FNBs. More patients without FNBs filed opioid claims postoperatively than patients who received FNBs.
