【摘要】 目的 探讨关节镜下不可吸收线“8”字缝合技术治疗前交叉韧带胫骨止点撕脱性骨折(knee anterior cruciate ligament avulsion fracture,KACLAF)的疗效。方法 选取我院2021年9月至2022年9月收治的67例KACLAF患者，其中男40例，女27例；平均年龄为(34.56±11.55)岁。通过膝关节活动度(range of motion,ROM)、双侧胫骨前移距离差值、等速力量测试和跳跃测试评估患者膝关节稳定性和活动度；膝关节损伤和骨关节炎结果评分(knee injury and osteoarthritis outcome score,KOOS)、国际膝关节文献委员会(International Knee Documentation Committee,IKDC)评分、Tegner活动量表(Tegner activity scale,TAS)和Lysholm膝关节评分量表(Lysholm knee scoring scale,LKSS)评估患者膝关节功能；疼痛视觉模拟评分(visual analog scale,VAS)和前交叉韧带生活质量(ACL quality of life,ACL-QOL)评估患者膝关节疼痛和术后生活质量。结果 与术前比较，术后3个月、6个月、9个月和12个月患者ROM均升高，双侧胫骨前移距离差值减小(P均<0.05)，等速力量测试(股四头肌60°/s、股四头肌180°/s、股四头肌300°/s、腘绳肌60°/s、腘绳肌180°/s和腘绳肌300°/s)和跳跃测试(单跳、三跳和侧跳)结果均逐渐递增(P均<0.05)；患者KOOS、IKDC、TAS和LKSS较术前均升高(P均<0.05)；患者ACL-QOL较术前均升高，VAS评分较术前均降低(P均<0.05)。结论 关节镜下不可吸收缝合线“8”字缝合技术能有效改善KACLAF术后膝关节功能、活动和稳定性，具有较高临床推广价值。更多还原

【Abstract】 Objective To investigate the efficacy of arthroscopic non-absorbable thread “8” suture technique in the treatment of knee anterior cruciate ligament avulsion fracture( KACLAF). Methods Sixty-seven patients with KACLAF admitted to our hospital between September 2021 and September 2022 were selected, including 40 males and 27 females. The mean age was( 34.56 ± 11.55) years. Knee stability and mobility were assessed by knee range of motion( ROM), bilateral anterior tibial translation distance difference, isometric strength test and jumping test. Knee functions were evaluated by Knee injury and osteoarthritis outcome score( KOOS), the International Knee Documentation Committee( IKDC) score, Tegner Activity Scale( TAS), and the Lysholm knee scoring scale( LKSS). Visual analog scale( VAS) for pain and the ACL quality of life( ACL-QOL) were used to assess knee pain and postoperative quality of life. Results Compared with the preoperative data, ROM was elevated at 3, 6, 9 and 12 months postoperatively; the differences in bilateral anterior tibial shift distance decreased( P < 0.05); isometric strength tests( quadriceps 60°/s, quadriceps 180°/s, quadriceps 300°/s, hamstrings 60°/s, hamstrings 180°/s, and hamstrings 300°/s) and jump tests( single, triple and lateral jumps) results were progressively increasing( P < 0.05);KOOS, IKDC, TAS and LKSS were higher than that preoperatively( P < 0.05); ACL-QOL was higher than that preoperatively; VAS was lower than that preoperatively( P < 0.05). Conclusions The arthroscopic non-absorbable suture “8” suture technique can effectively improve the movement and stability of the knee joint and knee function after KACLAF.更多还原
