【摘要】 [目的]回顾性分析、比较全膝关节置换术中髌骨置换与否对膝前痛发生的影响,为临床治疗提供参考。[方法]对1994年10月~2004年10月行人工全膝关节置换术病人125例(148膝)按髌骨置换(84膝)和未置换(64膝)分为2组,并对其随访资料进行分析,膝关节评分采用HSS评分系统,髌骨评分采用Feller评分标准。结果使用SPSS统计软件进行统计学分析。[结果]置换组HSS评分由术前的(39.6±39.8)分进步为末次随访时的(90.9±8.2)分,髌骨评分由(14.4±6.4)分进步到(25.2±4.8)分,膝前痛分数也由(4.6±3.9)分进步为(10.6±4.1)分;未置换组HSS评分由术前的(38.8±9.8)分进步为(90.2±8.9)分,髌骨评分由(14.2±6.2)分进步到(25.1±4.8)分,膝前痛分数也由(4.8±3.8)分进步为(10.3±4.1)分。2组患者末次随访时膝前痛均较术前明显减轻,差异有显著性意义;置换组与未置换组比较,膝前痛减轻的差别无显著性意义。[结论]无论髌骨置换与否,患者的合理选择和正确的手术操作是避免术后膝前痛的关键所在。更多还原

【Abstract】 [Objective]To compare retrospectively the clinical outcome in total knee arthroplasty with and without patellar resurfacing.[Method]From October 1994 to October 2004,125 patients(148 knees)with osteoarthritis were enrolled in the clinical trial of total knee arthroplasty,patients received resurfacing(84 knees)or retention patellar(64 knees).Evaluation was done from preoperatively to final followed-up postoperatively.The patients were scored using American HSS Score for knee and the Feller Score for patalla.The data were analyzed using SPSS software.[Result]In resurfacing patella group,the preoperative and final follow-up HSS scores of patients were(39.6±9.8)and(90.9±8.2)points respectively,scores of patailar were(14.4±6.4)and(25.2±4.8),scores of anterior knee pain were(4.6±3.9)and(10.6±4.1).In nonresurfacing patella group,the preoperative and final follow-up HSS scores of patients were(38.8±9.8)and(90.2±8.9)points respectively,scores of patallar were(14.2±6.2)and(25.1±4.8),scores of anterior knee pain were(4.8±3.8)and(10.3±4.1).There were significant differences in both groups preoperatively and postoperatively in anterior knee pain score,but no significant difference between the two groups in anterior knee pain score.[Conclusion]Whether the patellar replaced or not,the most importance for avoiding anterior knee pain postoperatively is the reasonable selection of patient and correct operation.更多还原
