关节镜清理配合腔内注射玻璃酸钠治疗膝关节骨性关节炎临床疗效观察

目的：探讨关节镜清理配合腔内注射玻璃酸钠治疗膝关节骨性关节炎的临床疗效。方法：关节镜下对117例（158膝）膝关节骨性关节炎患者行滑膜增生刨削，半月板修整或成形，剥离关节软骨及游离体取出术，骨缺损的关节面射频消融等。关节腔内注入玻璃酸钠2．5mL，加压包扎。以后每周注射1次，连续3-5周，术后行股四头肌锻炼及踝泵练习，48h拔出引流后行抬腿练习，1周拆线。结果：术后按Lysholm膝关节评分标准评定，出院时（86．9±11．2）优良率为89．8％，1年随访（78．2±12．8）优良率为80．5％。结论：关节镜清理配合腔内注射玻璃酸钠是治疗膝关节骨性关节炎的可靠方法。

Arthroscopic Treatments of Knee Osteoarthritis with Injection of Sodium Hyaluronate

Objective：To explore the arthroscopic treatments of knee osteoarthritis with injection of so-dium hyaluronate .Method： 117 cases （ 158 knees ） of knee osteoarthritis underwent synovial hyperplasia cleaning , shaped meniscus , removal of free articular cartilage and radiofrequency ablation of losing bone , then injected sodium hyaluronate 2.5mL, once a week for 3-5 weeks.Patients were guided by quadriceps ex-ercises and ankle pumps practice .Drainage were taken out after 48 hours and stitched one week later .Re-sult：Patients were evaluated by Lysholm knee score ,excellent rate was 89.8%（86.9±11.2） at discharge, excellent rate was 80.5%（78.2±12.8） at 1-year follow-up.Conclusion：Arthroscopy with injection of sodi-um hyaluronate is a reliable method for the treatment of osteoarthritis of the knee .
