Improving the cementation of the tibial component in knee arthroplasty : a study of four techniques in the cadaver.

Aims: The main objective of this study is to analyze the penetration of bone cement in four different full cementation techniques of the tibial tray.

Methods: In order to determine the best tibial tray cementation technique, we applied cement to 40 cryopreserved donor tibiae by four different techniques: 1) double-layer cementation of the tibial component and tibial bone with bone restrictor; 2) metallic cementation of the tibial component without bone restrictor; 3) bone cementation of the tibia with bone restrictor; and 4) superficial bone cementation of the tibia and metallic keel cementation of the tibial component without bone restrictor. We performed CT exams of all 40 subjects, and measured cement layer thickness at both levels of the resected surface of the epiphysis and the endomedular metaphyseal level.

Feasibility and diagnostic performance of including point-of-care ultrasound (POCUS) in preparticipation screening of young competitive athletes.

Optimal pre-participative screening in young athletes is still controversial. We sought to evaluate the strategy of including point-of-care ultrasound to electrocardiogram. In total, 1188 young competitive athletes were screened in different sports institutions.

Autologous Patellar Tendon Reconstruction after Total Knee Arthroplasty Infection with Skin Loss: Anatomical Study and Case Report.

Disruption of patellar tendon after total knee arthroplasty (TKA) is a devastating complication. If associated with infection or soft tissue defect, knee arthrodesis is usually indicated. The purpose of this study is to analyze, by means of an anatomical study, the feasibility of our novel technique for reconstruction of extensor apparatus after TKA infections with skin defects, combining gracilis (G) and semitendinosus (ST) tendon autografts and chimeric medial gastrocnemius-sural artery perforator (SAP) flap.

Anatomical evidence for a ponto-septal pathway via the nucleus incertus in the rat.

Hippocampal theta activity is involved in sensory-motor integration and constitutes a functional basis for mnemonic functions. The medial septum-diagonal band of Broca (MS/DBv) is a key structure as pacemaker of the oscillation. In addition, some brainstem reticular structures are crucial for the activation of MS/DBv.
