Cartilex by LASERIX

A second life for horses affected by arthrosis

What is Cartilex?

Cartilex: a unique method

Repair and heal precocious osteoarthrosis

Cartilage damages

Superficial wounds are normally treated by debridement of the damaged surface by means of mechanical shavers or by laser. Mechanical shavers are simple but they take away too much of the healthy cartilage.

Without treatment, the articulation continues to degenerate until complete destruction of the cartilage. It is then necessary to improve the present technics of chondroplasty in order to diminish the amount of healthy cartilage eliminated when the damaged or sick tissues are withdrawn in the clinical case of early osteoartrothis, and to smooth the damaged surface.

The laser has been well used in human medicine as it is the only instrument able of smoothing the hyaline cartilage without leaving a surface in form of a toothbrush, having bad mechanical properties and presenting the risk of widening the debrided area. However, the lasers used till now have a big risk of important thermial damages and demands a high skill to the surgeon. The laser beam should be used tangentially to the cartilage surface according to a precise angle.

Resurfacing the articular cartilage with the Cartilex method

In order to solve the problem of superficial cartilage wounds, Laserix has developed a patented method, that consists, first of all to apply a liquid dye that fixes at the surface of the cartilage. This dye is not toxic and has already been used in human medicine for numerous years. It absorbs the light from the laser, enabling to use much less power: even in the absence of the dye, the laser light diffuses without any danger through the articular cartilage.

The surgeon will resurface the articular cartilage with the Cartilex arthroscopic laser. He will withdraw a thin layer of damaged cartilage, leaving a smooth surface. The articulation can then start to function properly.

The optical tips is used like a rubber eraser. (1cm² lissé en 1 minute)

It has been observed that the laser light stimulates the chondrocytes: the thickness of the cartilage increases and the structure of the cartilage is restored.
