Arthroscopic treatment of meniscal lesion has been modified as technology advances have occured. However alternatives to conventional arthroscopic cutting tools, including electrocautery and CO2 lasers, have thus far met with limited success. The recent development of a sapphire tip has enabled the use of the neodymium --yttrium aluminum garnet (Nd-YAG)laser in a contact mode in a saline medium. This study compares the biology of the Nd-YAG laser to that of electrocautery and scalpel and electrocautery with regard to its effects on articulart carilage. It also has significant biologic advantages over electrocautery for meniscal lesions. Although in its infancy in the clinical setting the contact Nd-YAG laster represents the possible beginning of a new era for application of laser energy in arthroscopy.
