【摘要】 目的:寻找MRI显示的膝关节软骨损伤程度和关节镜手术后疗效的相关性,为临床提供膝关节镜手术适应征的指导。方法:2005年8月至2008年4月用膝关节镜手术治疗膝骨性关节炎87例,男44例,女43例;年龄16～67岁,平均46.3岁。对患者膝关节软骨按ICRSMR分级标准进行分级,并进行Lysholm评分。结果:87例87膝均进行了术后随访,时间12～30个月,平均23个月。关节软骨损伤:4级30例,3级23例,2级20例,1级12例,0级2例,平均(2.770±1.138)级。术后Lysholm评分59～100分,平均(95.170±7.556)分。两者相关系数r=-0.152,P=0.159>0.05,统计学分析无相关性,但有负相关趋势。结论:术前膝关节软骨的MRI(1.5T)分级不能作为关节镜手术指征判断的金标准,只是术前膝关节软骨的MRI(1.5T)分级高的患者术后疗效相对较差。更多还原

【Abstract】 Objective:To analyze the indication of arthroscope by examining the correlations between cartilage injury degree confirmed by MRI and postoperative effect. Methods:From Aug.2005 to April 2008,87 cases with knee osteoarthritis were treated by arthroscopes including 44 males and 43 females,aged from 16 to 67 years (means 46.3 years). Arthrodial cartilage of knee was graded by ICRS MR,and the therapeutic effect was evaluated by Lysholm scoring. Results:All 87 knees of 87 cases were followed-up for from 12 to 30 months (averaged 23 months). The cartilage injury degree of knees was graded as follows:grade 4 in 30 cases,grade 3 in 23 cases,grade 2 in 20 cases,grade 1 in 12 cases,grade 0 in 2 cases,means grade (2.770±1.138). Postoperative Lysholm score was from 59 to 100,means (95.170±7.556). Coefficient correlation (r) =-0.152, P=0.159>0.05. Although the results had no correlations between cartilage injury degree and Lysholm score,negative correlation tendency existed. Conclusion:The patients with higher grade of knee cartilage injury degree confirmed by MRI (1.5T) have worse effect after operation,the grade is not a gold standard as a operation indication in arthroscopic procedure.更多还原
