摘要
目的探讨生物可吸收挤压螺钉在膝关节韧带重建术中的应用和疗效。方法2002年4月～2004年8月，收治膝关节韧带损伤患者39例，其中男33例，女6例；年龄15～65岁，中位年龄25岁。单纯前交叉韧带（anterior cruciate ligament，ACL）损伤29膝，单纯后交叉韧带（posterior cruciate ligament，PCL）损伤6膝，ACL和PCL联合损伤4膝。合并内侧或外侧侧副韧带损伤3膝，合并后外侧结构损伤1膝。病程1周～8年。所有患者均行关节镜下或结合开放韧带重建术，采用自体移植物及生物可吸收螺钉固定。采用Lysholm临床评分系统对膝关节功能进行评估。结果术后34例获随访6～28个月，平均13．7个月。术后膝关节功能评分由术前43．6±13．4分，增加至术后85．4±16．3分，且差异有统计学意义（P〈0．05）。患者疼痛均消失，关节稳定，无交锁和无力等症状，均恢复关节活动度，螺钉无松动。术后1例出现感染征象，3例发生局部积液和滑膜炎，经保守治疗后好转。结论在膝关节韧带重建术中，生物可吸收挤压螺钉固定疗效可靠，能有效重建韧带，恢复膝关节稳定性。
Objective To evaluate the clinical results of bioabsorbable interference screw in knee ligament reconstruction. Methods From April 2002 to August 2004, 39 patients with knee ligament injury were treated, including 33 males and 6 females with a median age of 25 years （15 to 65 years）. The involved ligament included 29 anterior cruciate ligament of knee（ACL）, 6 posterior cruciate ligament of knee （PCL）,4 combined ACL and PCL, 3 medial collateral or lateral collateral ligaments of knee point and 1 posterolateral complex injury of knee. All of patients underwent anatomic ligament reconstructions under arthroscopy or open surgery by autografts and fixation with bioabsorbable interference screw. Results All 34 patients were followed up 6 to 28 months （mean 13. 7 months）. The patients were evaluated by Lysholm knee functional scales, the knee scores were 43.6±13.4 before operation and 85.4±16.3 after operation, showing significant difference （P〈0.05）. There was no limitation of range of motion and loosening of the screw. However, one case suffered from infection, and 3 cases suffered from effusion and synovitis after surgery and recovered after management. Conclusion Bioabsorbable interference screw fixation is a reliable method in knee ligament reconstruction and is effective to restore knee joint stability.
