Objective: To study the short-term effectiveness of absorbable anchor in repairing of partial anterior cruciate ligament (ACL) rupture.
Methods: Between December 2013 and February 2015, 22 patients with partial ACL rupture were repaired with absorbable anchor under arthroscopy. There were 12 males and 10 females with an average age of 27.5 years (range, 20-44 years). The injury located at left knee in 8 cases and at right knee in 14 cases. The time from injury to admission ranged from 2 to 13 days (mean, 9.8 days). Sixteen partial ACL ruptures combined with meniscus injury. The effectiveness was assessed by Tegner score, Lysholm score, International Knee Documentation Committee (IKDC) score, visual analogue scale (VAS) score, and MRI, as well as knee laxity was evaluated by KT-1000.
Results: All incisions healed at stage Ⅰ without any complication. All patients were followed up 12 months. ACL rerupture did not occurred during follow-up. There was no significant difference in Tegner score, Lysholm score, and IKDC score between before injury and at 12 months after operation ( P>0.05). And the median satisfaction VAS score was 9.5 (range, 9-10). The tibial anterior translation difference was 0.5 mm (range, 0-6 mm). MRI showed that the scarring and continuity of the ligament were rated as grade 1 in all patients.
Conclusion: Arthroscopic repairing by absorbable anchor is a feasible method for partial ACL rupture, with ideal knee function, good satisfaction, and satisfactory short-term effectiveness.
目的: 探讨关节镜下可吸收锚钉修复前交叉韧带部分损伤的早期疗效。.
方法: 2013 年 12 月—2015 年 2 月，收治 22 例前交叉韧带部分损伤患者。其中男 12 例，女 10 例；年龄 20～44 岁，平均 27.5 岁。左膝 8 例、右膝 14 例；受伤至入院时间 2～13 d，平均 9.8 d。合并半月板损伤 16 例。关节镜下采用可吸收锚钉修复损伤的前交叉韧带。采用 Tegner 评分、Lysholm 评分及国际膝关节文献委员会（IKDC）评分评价患者膝关节功能，同时采用疼痛视觉模拟评分（VAS）评估患者主观满意度；采用 KT-1000 测量仪评估膝关节松弛度，并行 MRI 检查评价韧带恢复情况。.
结果: 术后患者切口均 Ⅰ 期愈合，无手术相关并发症。患者均获随访 12 个月。随访期间患者均未出现前交叉韧带二次损伤。术后 12 个月 Tegner 评分、Lysholm 评分、IKDC 评分与受伤前比较，差异均无统计学意义（ P>0.05）；患者主观满意度 VAS 评分为 9～10 分，中位数为 9.5 分；双侧胫骨前移差值为 0～6 mm，中位数为 0.5 mm。MRI 结果提示 22 例患者连续性、纤维化信号强度分级均为 1 级。.
结论: 关节镜下可吸收锚钉修复前交叉韧带部分损伤可行，术后膝关节功能基本恢复正常，患者满意度高，早期疗效较好。.
