Background: Suppressive antibiotic therapy (SAT) after total joint arthroplasty (TJA) debridement, antibiotics, and implant retention (DAIR) maximizes reoperation-free survival. We evaluated SAT after DAIR of acutely infected primary TJA regarding: 1) adverse drug reaction (ADR)/intolerance; 2) reoperation for infection; and 3) antibiotic resistance.
Methods: Patients who underwent total knee arthroplasty (TKA) or total hip arthroplasty (THA) DAIR for acute periprosthetic joint infection at two academic medical centers from 2015 to 2020 were identified (n = 115).
Background: Total hip arthroplasty (THA) is a safe and effective procedure; however, complications such as dislocation, fracture, and infection still occur. It is still unclear whether the dislocation rate via the posterior approach (PA) is better, equal, or worse than the direct anterior approach. Our aim was to report the primary THA dislocation rate via the PA using enabling technology in a large consecutive series of patients.

- - The study utilized a deep learning algorithm to automate the analysis of knee alignment parameters within the Coronal Plane Alignment of the Knee (CPAK) classification, focusing on a large dataset of patients with arthritis.
- - Validation showed that the algorithm's CPAK angle measurements and classifications were consistent with those of a trained orthopedic surgeon, indicating high accuracy and efficiency.
- - Findings indicated differences in knee phenotypes based on sex and baseline Kellgren-Lawrence scores, suggesting that these factors should be considered in knee arthroplasty planning.
Background: The purpose of this study was to evaluate postoperative outcomes at minimum 5-year follow-up in patients following unicompartmental knee arthroplasty (UKA) compared to a matched cohort of total knee arthroplasty (TKA) patients.
Methods: Patients who had primarily medial compartment osteoarthritis (OA) who met criteria for medial UKA underwent TKA or medial UKA between 2014 and 2015 at a single institution, matched for age, sex, and body mass index. There were 127 UKAs in 120 patients and 118 TKAs in 116 patients included with minimum 5-year follow-up (range, 6 to 8).
Aims: Although CT is considered the benchmark to measure femoral version, 3D biplanar radiography (hipEOS) has recently emerged as a possible alternative with reduced exposure to ionizing radiation and shorter examination time. The aim of our study was to evaluate femoral stem version in postoperative total hip arthroplasty (THA) patients and compare the accuracy of hipEOS to CT. We hypothesize that there will be no significant difference in calculated femoral stem version measurements between the two imaging methods.

- The study aimed to improve the measurement of tibial coronal alignment in total knee arthroplasty by accurately identifying the ankle joint center using artificial intelligence and different anatomical landmarks.
- Researchers analyzed full-limb radiographs from 250 patients, training a deep learning model to calculate knee alignment angles and comparing these results against a defined radiological ankle center.
- Findings showed that using the radiological ankle center was highly accurate compared to traditional radiologist measurements, with certain landmark adjustments potentially providing similar alignment accuracy.
