  • Title: Partial meniscectomy using the neodymium:YAG laser. An in vitro study.
    Author: Bickerstaff DR, Wyman A, Laing RW, Smith TW.
    Journal: Arthroscopy; 1991; 7(1):63-7. PubMed ID: 2009122.
    Abstract:
    We have evaluated, in an in-vitro study, the thermal effects of the neodymium:YAG (Nd:YAG) contact laser on meniscal tissue. There was no significant difference with regard to time taken to divide the meniscus or depth of necrosis between the two power settings used (25 and 30 W). A significantly greater (p less than 0.005) amount of energy, however, was expended at the higher power setting. The heat from the laser probe dissipated rapidly into the surrounding water without causing significant lateral thermal tissue damage. The Nd:YAG contact laser has features such as the ability to be transmitted through aqueous solutions, fiberoptic delivery, precise thermal tissue effects, and tactile feedback that would be beneficial in arthroscopic surgery. Although experimental, we suggest further clinical evaluation of its potential.
