Spontaneous Minced Cartilage Procedure for Unexpectedly Large Femoral Condyle Surface Defect

Spontaneous Minced Cartilage Procedure for Unexpectedly Large Femoral Condyle Surface Defect

Articular cartilage defects at the knee joint are being identified and treated with increasing frequency. Chondrocytes may have strongest potential to generate high-quality repair tissue within the defective region, in particular when large diameter defects are present. Autologous chondrocyte implantation is not available in every country. We present a case where we spontaneously covered an acu...

The Healing Effect of Bioglue in Articular Cartilage Defect of Femoral Condyle in Experimental Rabbit Model

BACKGROUND The full-thickness articular cartilage defects of knee have a poor healing capacity that may progress to osteoarthritis and need a knee replacement. This study determines the healing effect of bioglue in fullthickness articular cartilage defect of femoral condyle in rabbit. METHODS Forty-eight male rabbits were randomly divided into four equal groups. In group A, 4 mm articular car...

Osteochondral Allograft Transplantation for Treatment of Medial Femoral Condyle Defect

Chondral lesions of the knee can affect the young, active population, thereby causing severe morbidity and a large economic burden. Although numerous approaches have been described in the literature, restoration of hyaline cartilage has yet to be shown. Specifically, larger, full-thickness cartilage defects remain a challenge. This Technical Note details our technique for biologic unicompartmen...

Unexpectedly large surface gravities for acoustic horizons?

Acoustic black holes are fluid-dynamic analogues of general relativistic black holes, wherein the behaviour of sound waves in a moving fluid acts as an analogue for scalar fields propagating in a gravitational background. Acoustic horizons, which are intimately related to regions where the speed of the fluid flow exceeds the local speed of sound, possess many of the properties more normally ass...
