摘要
目的：观察关节镜下微骨折技术（Microfracture）修复膝关节软骨全层缺损的疗效。方法：回顾性分析2002年1月～2005年7月北京大学运动医学研究所收治的43例膝关节软骨全层缺损患者的情况，平均随访15．9±8．8个月（6～47个月）。采用Tegner、Meyers、Lysholm评分作为疗效判定标准。结果：微骨折技术修复膝关节软骨全层缺损总有效率为87．0％，其中，疗效优27个膝关节（58．7％），疗效良13个膝关节（28．3％），疗效差3个膝关节（6．5％）。平均Tegner评分从1．5±1．3提高到4．8±1．5（P〈0．01）；平均Meyers评分从9．9±1．9提高到16．4±2．0（P〈0．01）；平均Lysholm评分从41．8±12．5提高到82．7±12．6（P〈0．01）。手术前后疗效比较有统计学差异（P〈0．01）。微骨折术疗效与患者的性别、半月板损伤的相关性不明显（P〉0．05），但与患者的年龄、外伤、软骨缺损面积存在相关性（P〈0．05）。结论：关节镜下微骨折技术修复膝关节软骨全层缺损操作简单、安全，微创，疗效可靠，是较为实用的关节软骨修复技术。
Objective To study the clinical effect of repaired full- thickness articular chondral defects of the knee by arthroscopic microfracture technique. Methods From January 2002 to July 2005, forty - three patients who suffered from full - thickness articular cartilage defects and treated with arthroscopic microfracture technique were studied retrospectively. Patients were followed up for an average of 15.9 ± 8.8 months （range： 6 - 47months）. Tegner Activity level scale, Meyers score, Lysholm score were used for the evaluation before and after operation. Results Total effective rate of clinical outcome was 87.0%, including 27 cases with excellent result （58.7%） and 13 cases with good result （28.3%）. Meanwhile,there were 3 cases showed bad result （6.5%）. Mean Tegner Activity level scale improved from 1.5 ±1.3 to 4.8± 1.5 （ P 〈 0.01）. Mean Meyers score improved from 9.9±1.9 to 16.4±2.0 （P 〈 0.01） and mean Lysholm score improved from 41.8±12.5 to 82.7±12.6 （P 〈 0.01）. No significant correlation was noted between Lysholm improvement and gender or menisci tear（ P 〉 0.05）. However, there existed a negative correlation between Lysholm improvement and age, trauma, defect area （ P 〈 0.05 ）. Conclusion Arthroscopic microfracture technique was simple, safety, micro - invasive and effective, appeared to be a practical surgical technique for the treatment of articular chondral lesions of the knee.
