摘要目的：比较前交叉韧带（ ACL）部分断裂后采用射频修整术与加强性单束重建手术的疗效差异。方法回顾性收集54例ACL部分断裂患者的临床资料。根据治疗方法不同被分成两组：关节镜下射频修整组16例和加强性单束重建术组38例。所有患者随访2年。评价指标包括：IKDC评分、Ly?sholm评分、Tegner评分、膝关节活动度（ ROM）和Kneelax关节动度测量仪测量结果，比较两组的差异。结果射频修整术组患者Kneelax测量结果术前为（4．4±0．9） mm，术后为（5．0±1．5） mm，差异无统计学意义（t＝1．372，P＝0．183）；加强性单束重建术组患者术前为（4．7±0．8） mm，术后为（1．7±1．0） mm，术后患膝稳定性显著性提高（ t＝14．444，P＝0．000）；两组患者术后结果加强性单束重建术组显著性强于射频修整术组（t＝9．228，P＝0．000）。射频修整术组患者ROM术前为（105．4±22．5）°，术后为（123．5±11．4）°，差异有统计学意义（t＝59．189，P＝0．000）；Lysholm评分术前为65（51，90）分，术后为86（59，100）分，差异有统计学意义（Z＝3．852，P＝0．000）；Tegner评分术前为3（1，5）分，术后为6（1，9）分，差异有统计学意义（Z＝4．637，P＝0．000）。加强性单束重建术组患者患者ROM术前结果为（99．4±21．9）°，术后为（125．3±10．9）°，差异有统计学意义（t＝6．527，P＝0．000）；Lysholm评分术前为65（51，89）分，术后为85（59，100）分，差异有统计学意义（Z＝4．427，P＝0．000）；Tegner评分术前为3（1，5）分，术后为6（1，9）分，差异有统计学意义（Z＝3．961，P＝0．000）。结论 ACL部分断裂后采用加强性单束重建手术治疗比采用射频修整更有利于患膝稳定性的恢复。

abstractsObjective To compare the outcomes between radiofrequency modification and augmentation reconstruction in the treatment for partial anterior cruciate ligament( ACL) tears. Methods Fifty?four patients with partial ACL tears were divided into radiofrequency modification group( n=16) and augmentation reconstruc?tion group( n=38) according to different treatment methods. Minimum follow?up was 2 years. Patients were eval?uated just after the injury and at the latest follow?up with several parameters, including the international knee documentation committee( IKDC) score,Lysholm knee score,Tegner activity rating,range of motion ( ROM) and the kneelax arthrometer. Results The kneelax was (4. 4±0. 9) mm of preoperative, (5. 0±1. 5) mm of post?operative in radiofrequency modification group,the difference was no signifiacnt( t=1. 372,P=0. 183);in aug?mentation reconstruction group was (4. 7±0. 8) mm and (1. 7±1. 0) mm respectively,the knee stability was in?crease significantly postoperative;knee stability was significantly improved in the augmentation reconstruction group compared with the radiofrequency modification group( t=9. 228,P=0. 000) . In radiofrequency modifica?tion group,ROM,Lysholm score and Tegner score were improved significantly between the results pre?and post?operatively((105. 4±22. 5)° vs. (123. 5±11. 4)°,t=59. 189,P=0. 000;65(51,90)) points vs. 86(59,100) points,Z=3. 852,P=0. 000;3(1,5) points vs. 6(1,9) points,Z=4. 637,P=0. 000). In augmentation recon? struction group, ROM,Lysholm score and Tegner score were improved significantly between the results pre?and post?operatively((99. 4±21. 9)° vs. (125. 3±10. 9)°,t=6. 527,P=0. 000;(65(51,89) points vs. (85 (59, 100) points,Z=4. 427,P=0. 000;3(1,5) points vs. 6(1,9) points,Z=3. 961,P=0. 000). Conclusion Augmentation reconstruction technique is more beneficial to the knee stability than radiofrequency modification in the treatment for the partial ACL tears.
