正交设计下膝关节外周神经射频消融治疗膝关节骨关节炎
Orthogonal design the knee peripheral nerve radiofrequency ablation treatment of knee osteoarthritis
摘要
Abstract
Objective Explore a new treatment by orthogonal design of no empty cases :treatment of knee osteoarthritis by nerve locator ,for knee joint peripheral nerve branch implement selective radio frequency ablation .Methods According to patients′age ,body mass index ,gender ,organs ,in the course of the disease ,preoperative VAS score ,first divided into nine groups ,each group of four people ,then randomly assigned to four groups and each group 9 cases ,a total of 36 people .With nerve locator ,design of 4 factors and 3 levels ,no empty cases of orthogonal design ,every time 9 people by radio frequency ablation treatment of knee joint pe-ripheral nerve .Repeat 4 times to reduce the sampling error ,obtain the VAS difference between postoperative 1 week and preopera-tive .Results The best combination of treat knee joint osteoarthritis by Radio frequency ablation was A3B3C(1-3)D(1-3) .Selective radio frequency ablation knee peripheral nerve branch target rf temperature is 90 ℃ ,120 seconds ,lidocaine concentration(0 .5% to 2% ) and lidocaine measurement (0 .5 to 1 .5 mL) .Conclusion Using the orthogonal design of no empty cases ,for knee joint pe-ripheral nerve branch for selective radio frequency ablation by nerve locator .Treatment of knee joint osteoarthritis in A3B3C(1-3) D (1-3) combination effect exact ,minimally invasive ,safe ,accurate location ,the treatment effect is good ,low cost ,simple and high ef-ficiency .关键词
