关节镜下微骨折术治疗膝关节软骨损伤的临床疗效观察

Clinical efficacy of arthroscopic microfracture surgery on knee cartilage injury

目的：探讨关节镜下微骨折术在膝关节软骨损伤治疗中的临床疗效。方法将76例研究对象随机分为治疗组（TG，n=38）与对照组（CG，n=38），TG行关节镜下微骨折术，CG行关节清理术，术后随访6～18个月，比较两种不同治疗方法的临床疗效。结果 TG患者HSS评分（86.36±4.17）分，CG患者HSS评分（63.71±6.20）分；两组比较差异有统计学意义（t=35.785， P=0.000）。TG中HSS评分＞85分、60～85分、＜60分分别为15例、19例及4例；而CG分别为7例、13例和18例；两组比较差异有统计学意义（χ^2=6.258，P=0.013）。TG显效14例，有效20例，无效4例，总有效率为89.47%，与CG总有效率为50.00%相比，差异有统计学意义（χ^2=8.130，P=0.000）。TG中仅3例出现轻微疼痛，CG中10例出现关节肿胀；两组比较，TG明显低于CG（χ^2=4.547，P=0.033）。结论关节镜下微骨折术具有、术后并发症少等优点，对于膝关节软骨缺损患者关节功能的改善有积极的促进作用。

ObjectiveThis study aims to investigate the clinical efficacy of arthroscopic microfracture surgery on the knee cartilage injury.Methods76 patients were randomly divided into treatment group （TG,n=38） and control group （CG,n=38）. TG were performed arthroscopic microfracture surgery, and CG was performed joint debridement. All the patients were had a 6-18 months follow-up. ResultsThe HSS score was significant higher of 86.36±4.17 in TG than that of 63.71±6.20 （t=35.785, P=0.001）. The number of patients whose HSS score〉85, 60-85, 〈60 were 15, 19 and 4 in TG respectively, and were 7, 13 and 18 in CG respectively; there was significant difference between two groups （χ^2=6.258, P=0.013）. 14 cases were in a significant effect, 20 cases were in effective, 4 cases were in invalid, and the total effective rate was 89.47%, which was statistically significant better than CG （50.00%）（χ^2=8.130, P=0.000）. Only 3 cases had slight pain in TG, which were significantly lower than that of 10 cases in CG （χ^2=4.547,P=0.033）.ConclusionArthroscopic microfracture surgery has the advantages of reliable curative effect, simple operation, less postoperative complications. It can improve the function of knee joint function of patients with articular cartilage defects.
