Fifty-one patients had arthroscopic partial meniscectomies with electrosurgery between 1982 and 1985. Two patients who had undergone prior meniscectomies with electrosurgery had biopsies of the old excision site at repeat arthroscopy, necessitated by new injuries. Three different combinations of electrocautery tips and either a standard electrocautery generator or a new electrocautery generator specifically designed for arthroscopic electrosurgery were used in different combinations. Depth of damage as defined by the Trichrome stain was measured by a micrometer. A rating summary of the quality of resection technique was also performed. Overall, the newly developed electrocautery generator and the newly developed electrocautery tips were not beneficial in reducing the depth of damage. The average depth of damage was .29 mm. Forty-seven percent of patients showed no histologic evidence of damage from the electrosurgical resection. The two individuals with repeat biopsies showed normal histology. Arthroscopic partial meniscectomy with electrosurgery causes a very thin layer of tissue damage. This appears to resolve with time. Recently developed instruments specifically designed for arthroscopic electrosurgery do not appear to decrease the depth of damage.
1982年至1985年间，51例患者接受了关节镜下半月板部分切除术并使用了电外科手术。两名曾接受过电外科半月板切除术的患者，因新伤在再次关节镜检查时对旧切除部位进行了活检。不同组合使用了三种不同的电灼尖端，以及标准电灼发生器或专门为关节镜电外科手术设计的新型电灼发生器。用三色染色法定义的损伤深度用测微计测量。还对切除技术质量进行了评级总结。总体而言，新开发的电灼发生器和新开发的电灼尖端在减少损伤深度方面并无益处。平均损伤深度为0.29毫米。47%的患者没有电外科切除造成损伤的组织学证据。两名再次活检的患者组织学表现正常。关节镜下半月板部分切除术加电外科手术会造成非常薄的一层组织损伤。这种损伤似乎会随时间消退。最近专门为关节镜电外科手术设计的器械似乎并未减少损伤深度。
