Preoperative planning for total knee arthroplasty (TKA) is essential for streamlining operating room efficiency and reducing costs. Digital templating and patient-specific instrumentation have shown some value in TKA but require additional costs and resources. The purpose of this study was to validate a previously published algorithm that uses only demographic variables to accurately predict TKA tibial and femoral component sizes. ⋯ This prospective series of patients validates a simple algorithm to predict component sizing for TKA with high accuracy based on demographic variables alone. Surgeons can use this algorithm to simplify the preoperative planning process by reducing unnecessary trays, trials, and implant storage, particularly in the community or outpatient setting where resources are limited. Further assessment of components with less than 2.5-mm differences between femoral sizes is required in the future to make this algorithm more applicable worldwide.

Perioperative periprosthetic femur fractures (PPFx) after total hip arthroplasty (THA) remain a leading cause of early stem failure and revision and are associated with high rates of morbidity and mortality. American Joint Replacement Registry (AJRR) data have been analyzed to determine the relationship of femoral stem fixation to PPFx revision. ⋯ Mirroring other studies and national registries, there was an association between cementless fixation and PPFx in AJRR. Nevertheless, AJRR data demonstrate a trend of increasing utilization of cementless femoral fixation for THA and hemiarthroplasty, with cementless fixation accounting for 93% of THA stems with early periprosthetic fracture. Additional analysis is needed to better understand this phenomenon, especially in the elderly.

Comparative Study Observational Study
Revision Versus Primary Hospital Consumer Assessment of Healthcare Providers and Systems Scores in Total Joint Arthroplasty.
The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) score is a nationally standardized measure of a patient's inpatient experience. This study aims to assess whether HCAHPS scores differ between patients undergoing primary total joint arthroplasty (TJA) and patients undergoing revision TJA. ⋯ Patients undergoing primary THA report higher HCAHPS scores than those undergoing revision THA, while revision TKA demonstrated a general trend toward higher scores when compared to primary TKA patients. This publicly reported quality measurement metric which factors into physician reimbursement may be biased by the patient's health status, the complexity of the surgical procedure, and length of stay in hospital rather than a true reflection of the quality of their hospital experience.

Postoperative glucose levels after total joint arthroplasty are important to monitor as hyperglycemia has been linked to complications such as periprosthetic joint infection. The purposes of this study were to identify how postoperative glucose values vary during the perioperative period and determine the optimal time to check glucose levels to best evaluate for hyperglycemia. ⋯ Most patients who underwent total joint arthroplasty are hyperglycemic postoperatively, and 9 PM on the night of surgery may be the most sensitive time for detecting hyperglycemia in both diabetic and nondiabetic patients, in contrast to traditional POD 1 levels.
