Prolonged hospitalization is known to be associated with a loss of cognitive performance. Does playing video games (VGs) developed to improve cognitive properties delay this loss or even lead to an increase in cognitive performance? We performed a 10-day longitudinal study of patients who received total hip arthroplasty. We compared 16 patients (6 male) aged 66 ± 9 years (mean ± standard deviation) who played Dr.

Purpose: To compare cartilage repair tissue at the femoral condyle noninvasively after matrix-associated autologous chondrocyte transplantation using Hyalograft C, a hyaluronic-based scaffold, to cartilage repair tissue after transplantation using CaReS, a collagen-based scaffold, with magnetic resonance imaging using morphologic scoring and T2 mapping.
Study Design: Cohort study; Level of evidence, 3.
Objectives: To use T2 and T2* mapping in patients after matrix-associated autologous chondrocyte transplantation (MACT) of the knee, and to compare and correlate both methodologies.
Methods: 3.0-Tesla MRI was performed on 30 patients (34.
The study's objective was to investigate if transplanted chondrocyte or periosteal cell spheroids have influence on ingrowing bone marrow-derived cells in a novel cartilage repair approach in miniature pigs. Autologous rib chondrocytes or periosteal cells were cultured as spheroids and press-fitted into cavities that were milled into large, superficial chondral lesions of the patellar joint surface. Within the milled cavities, the subchondral bone plate was either penetrated or left intact (full-thickness or partial-thickness cavities).

A combined injury of both the TA and the extensor hallucis longus (EHL) tendons has not yet been reported. Within the scope of this work we will prove that tendon transfers in cases of combined tendon injuries are a reasonable course of action in order to achieve the aim of a functional reconstruction.

The aim of this study was to evaluate the influence of exogenous surfactant administration on surfactant properties in a model of single lung transplantation.
Methods: We performed heterologous, left lung transplantation (+4 degrees C ischemia; 24 hours, Euro-Collins solution) in 6 foxhounds (untreated) and in 6 animals that received calf lung surfactant extract (Alveofact) prior to explantation (only donor lung; 50 mg/kg body weight) and immediately after onset of reperfusion (both lungs, 200 mg/kg body weight).
