改良髌下膝关节腔穿刺术在膝骨关节炎中的应用

MODIFIED INFRAPATELLAR KNEE-CAVITY PUNCTURE IN THE TREATMENT OF KNEE OSTEOARTHRITIS

为观察改良髌下膝关节腔穿刺术在膝骨关节炎(OA)中的应用价值。选择膝OA患者256例,随机分为3组,采用不同的膝关节腔穿刺术行关节腔内注射玻璃酸钠治疗。A组89例,采用改良髌下膝关节腔穿刺术;B组82例,采用常规髌上膝关节腔穿刺术;C组85例,采用常规髌下膝关节腔穿刺术。观察各组穿刺过程中疼痛程度、是否1次穿刺成功、注射药物后出现局部疼痛及肿胀情况、是否完成1个疗程治疗,及治疗前后主要症状、体征及B超所示关节腔积液的改善情况。结果A组穿刺过程中疼痛程度及1次穿刺成功者比例、注射药物后出现局部疼痛和肿胀比例、未完成1个疗程治疗比例、关节腔积液和关节活动度的改善等和临床疗效评价均明显优于B组和C组(P<0.005)。表明改良髌下膝关节腔穿刺术是治疗膝骨关节炎的最佳方法。

In order to observe the application value of modified infrapatellar knee-cavity puncture(KCP) in the treatment of knee osteoarthritis(KOA),256 cases of KOA were randomly divided into Groups A (n=89 cases),B(n=82 cases) and C(n=85 cases) and treated by different KCP and sodium hyaluronate injection: Groups A by the modified infrapatellar KCP,Group B by the conventional suprapatellar KCP and Groups C by the conventional infrapatellar KCP;the observed objects included: the pains during the puncture,successful rates of one puncture,local pains and swellings after the injection,one treatment course finished or not and improvement of the main symptoms,signs and hydrarthrosis.The results showed that Groups A had an obvious advantage over Group A and Group C in the observed objects and clinical therapeutic effect (P < 0.005),suggesting that the modified infrapatellar KCP is the best method for treating KOA.
