[Experimental results of cartilage abrasion with an excimer laser. Histologic and electron microscopy studies].
Experiments carried out with cadaver cartilage from the tibiaplateau were performed using an excimer-laser to demonstrate its use for cartilage removal. Laser applications resulted in a cartilage ablation depending on energy density and the number of applied pulses. Observations made using scanning electron-microscopy showed the influence of the pulse rate on the surface structure. Transmission-electron-microscopical investigation showed the existence of a superficially altered layer with a depth of approx. 6 microns. On the basis of the results obtained, the conclusion can be reached that application of excimer-lasers for cartilage removal in a view of future endoscopic surgery could become a valuable alternative to the existing methods in the therapy of osteoarthritis.
