Background: The two-stage surgical protocols used for the treatment of periprosthetic joint infection following total knee arthroplasty are associated with marked patient morbidity. As such, alternatives, such as durable "1.5-stage" spacer constructs, have gained popularity.

J Am Acad Orthop Surg
April 2025
Article Synopsis
- This study investigates the rotational alignment of the distal femur during distal femoral replacement surgery, an area where standard references are often lacking.
- It involved analysis of CT scans from adults, measuring angles related to various anatomical landmarks at different distances from the joint line, revealing distinct patterns of rotation.
- The findings suggest that while the Whiteside line is a reliable reference for positioning the femoral implant, attention must be paid to other anatomical features to avoid improper internal rotation at higher resection levels.
Article Synopsis
- This study investigates the rates of venous thromboembolism (VTE) among patients undergoing surgery for cancer-related bone fractures while receiving different anticoagulants: enoxaparin, apixaban, rivaroxaban, or aspirin (ASA).
- Analysis was conducted using patient data from the Premier Healthcare Database between 2015 and 2021, comparing VTE occurrences among the different medication cohorts, with enoxaparin as the control.
- Results indicated that enoxaparin was associated with lower VTE rates compared to apixaban but higher than those treated with ASA, suggesting that ASA may be a safer option for certain patients with minimal risk factors for VTE post-surgery.
Introduction: As the volume of technology-assisted total hip arthroplasty (THA) increases, there is a need to characterise the outcomes of robotic-assisted (RA) and computer-navigated (CN) THA. The goal of this study was to assess outcomes and opioid consumption following CN-THA and RA-THA compared to conventionally-instrumented (CON) THA.
Methods: The Premier Database was queried for all patients who underwent primary, elective THA from 2015-2020.
Complete Blood Count Ratios Predict Adverse Events After Total Joint Arthroplasty.
J Am Acad Orthop Surg
December 2024
Article Synopsis
- The study evaluates the relationship between complete blood count-based ratios (CBRs) like NLR, MLR, PLR, and SII with postoperative complications, hospital length of stay (LOS), and mortality in patients undergoing total joint arthroplasty.
- Using a large database, the research identified specific threshold values for these CBRs that are linked to increased risk of complications and prolonged LOS after surgery.
- The findings highlight the significance of CBRs in predicting surgical outcomes, which can potentially guide preoperative assessments and improve patient management.
Medicare Advantage healthcare plans may present undue impediments that result in disparities in patient outcomes. This study aims to compare the outcomes of patients who underwent STS resection based on enrollment in either traditional Medicare (TM) or Medicare Advantage (MA) plans. The Premier Healthcare Database was utilized to identify all patients ≥65 years old who underwent surgery for resection of a lower-extremity STS from 2015 to 2021.

This study aims to describe modern utilization trends in CN-TKA, RA-TKA, and traditionally-instrumented (TD) TKA and to assess for differences in postoperative complications and opioid consumption by procedure type.
Methods: A national database was queried to identify primary, elective TKA patients from 2015 to 2020.
