Navigated instrumentation and ligament tensioning device enhances initial gap acquisition during total knee arthroplasty procedure: A cadaveric study.
J Exp Orthop
January 2025
Department of Orthopaedic Surgery and Trauma University Center of Montpellier, University of Montpellier Montpellier France.
Purpose: Gap-balanced total knee arthroplasty (TKA) technique relies on initial ligament evaluation, particularly in patient-specific implantation using computer-assisted technologies. This cadaveric study aimed to compare the reproducibility and reliability of medial and lateral gap measurements between manual stress testing and dynamic ligament balancer.
Methods: Initial gap acquisitions were assessed from eight cadaveric knees (four specimens) during the same navigated TKA procedure by five differently skilled surgeons (three seniors and two juniors).
Anatomic Distal Biceps Tendon Repair With All-Suture Cortical Buttons.

Acute, traumatic distal biceps tendon ruptures are a common injury in the middle-aged athletic male population, with direct anatomic surgical repair being the most effective technique to restore maximal strength. Multiple techniques for distal biceps tendon repair have been described, including single- or dual-incision approaches and tendon fixation with cortical buttons, interference screws, suture anchors, and transosseous sutures. In this Technical Note, we demonstrate an anatomic distal biceps tendon repair technique with a single-incision approach using 2 all-suture cortical buttons.

Ten coordination compounds, [Cu(L)Cl] (), [Cu(L)NO] (), [Cu(L)Cl] (C3), [Cu(L)NO] (), [Cu(L)Cl] (), [Cu(L)NO] (), [Cu(L)NO] (), [Cu(L)Cl] (), [Cu(L)Cl] (), and [Cu(L)NO] (), containing pyridine derivatives of -methoxyphenyl-thiosemicarbazones were synthesized and characterized. The molecular structure of four compounds was investigated using single crystal X-ray diffraction. Spectral analysis techniques such as FT-IR, H NMR, C NMR, elemental analysis, and molar conductivity were used for all the synthesized compounds.

In this work, we have studied the thermodynamic properties of the Van der Waals black hole in the framework of the relativistic Kaniadakis entropy. We have shown that the black hole properties, such as the mass and temperature, differ from those obtained by using the the Boltzmann-Gibbs approach. Moreover, the deformation κ-parameter changes the behavior of the Gibbs free energy via introduced thermodynamic instabilities, whereas the emission rate is influenced by κ only at low frequencies.

Article Synopsis
- Bloodstream infections need quick bacterial identification for effective treatment, with traditional methods being slow.
- The study compared direct identification using MALDI-TOF MS with the post-culture method, finding that while direct identification had a lower success rate (64.8%), it provided results in under an hour.
- Despite its limitations, the direct method could significantly enhance diagnosis speed, making it a potentially valuable tool in conjunction with established methods.
