Arthroscopic treatment of meniscal lesions has been modified as technological advances have occurred. 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 techniques with respect to its effects on articular cartilage and the meniscus. The contact Nd-YAG laser has advantages over both scalpel and electrocautery with regard to its effects on articular cartilage. It also has significant biologic advantages over electrocautery for meniscal lesions. Although in its infancy in the clinical setting, the contact Nd-YAG laser represents the possible beginning of a new era for application of laser energy in arthroscopy.
随着技术的进步，关节镜下半月板损伤的治疗方法也得到了改进。然而，包括电灼术和二氧化碳激光在内的传统关节镜切割工具的替代方法，迄今为止取得的成功有限。蓝宝石尖端的最新发展使得钕钇铝石榴石（Nd-YAG）激光能够在生理盐水介质中以接触模式使用。本研究比较了Nd-YAG激光与电灼术和手术刀技术在对关节软骨和半月板的影响方面的生物学特性。接触式Nd-YAG激光在对关节软骨的影响方面优于手术刀和电灼术。对于半月板损伤，它在生物学上也比电灼术具有显著优势。尽管接触式Nd-YAG激光在临床应用中尚处于起步阶段，但它代表了激光能量在关节镜检查中应用新时代的可能开端。
