The purpose of this study was to evaluate the clinical effect of electrocautery on the reduction of pain in patellar non-resurfacing bilateral total knee arthroplasty.
A total of 50 patients were enrolled into this study; all patients had undergone bilateral patellar non-resurfacing total knee arthoplasty at our hospital, between January 2007 to December 2008. The minimum follow-up period was 1 year. The electrocautery of the patellar rim was performed randomly on one side only. The clinical results were evaluated between the electrocautery group and the non-electrocautery group based on measures of anterior knee pain, range of motion, American Knee Society clinical rating score, Feller knee score, Western Ontario and McMaster Universities score, and radiographic analysis.
There were statistically significant differences between preoperative and postoperative status for all parameters. There were no statistically significant differences noted between the electrocautery group and the non electrocautery group for all parameters.
Electrocautery of patellar rim is thought to be less effective in reducing anterior knee pain.
本研究旨在评估电灼术在双侧髌骨未置换全膝关节置换术中减轻疼痛的临床效果。
本研究共纳入50例患者；所有患者于2007年1月至2008年12月在我院接受了双侧髌骨未置换全膝关节置换术。最短随访期为1年。仅对一侧髌骨边缘进行随机电灼。基于膝前疼痛测量、活动范围、美国膝关节协会临床评分、费勒膝关节评分、西安大略和麦克马斯特大学评分以及影像学分析，对电灼组和非电灼组的临床结果进行评估。
所有参数术前和术后状态之间存在统计学显著差异。电灼组和非电灼组之间所有参数均未发现统计学显著差异。
髌骨边缘电灼术在减轻膝前疼痛方面效果较差。
