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.
钇铝石榴石（Nd:YAG）接触式激光对半月板组织的热效应。在所使用的两种功率设置（25瓦和30瓦）之间，在切开半月板所需时间或坏死深度方面没有显著差异。然而，在较高功率设置下消耗的能量明显更多（p小于0.005）。激光探头产生的热量迅速消散到周围的水中，而不会造成明显的侧向热组织损伤。Nd:YAG接触式激光具有诸如能够透过水溶液传输、光纤传输、精确的热组织效应以及触觉反馈等特性，这些特性在关节镜手术中会很有益处。尽管是实验性的，但我们建议对其潜力进行进一步的临床评估。
