关节镜下保留残端重建前交叉韧带与不保留残端重建的Meta分析

BACKGROUND: There are controversies about preserving the remnant in the anterior cruciate ligament reconstruction procedure because of its uncertain therapeutic effects. OBJECTIVE:To compare the efficacy and safety of preserving-remnant with removing-remnant for arthroscopic anterior cruciate ligament reconstruction using a meta-analysis. METHODS: A computer-based online search was conducted in PubMed, Embase, the Cochrane Library, CDSR, CBM, and CNKI databases by using the English key words of “anterior cruciate ligament AND remnant (OR stump) AND randomized controlled trial (RCT) OR quasi-RCT” and the Chinese key words of “anterior cruciate ligament reconstruction, preserving-remnant, removing-remnant” to screen the relevant articles published from 1995 to July 2015. Meta-analysis was performed using Review Manager 5.3 software. RESULTS AND CONCLUSION:A total of 13 randomized controlled trials were included. The meta-analysis results showed that there were no statistically significant differences in KT1000/2000 scores (OR=-0.28, 95%CI: -0.76-0.20, P=0.25), the good rate of synoveal coverage (OR =-0.30, 95%CI: -0.30-0.90, P=0.32), and the incidence of cyclops leions (OR=0.87, 95%CI: 0.63-2.90, P=0.44). Postoperative Lysholm scores (OR=2.45, 95%CI: 0.52-4.39, P=0.01), proprioceptive function (OR=-1.72, 95%CI: -3.32 to 0.13, P=0.03), tunnel enlargement (OR=-0.66, 95%CI: -1.08 to -0.23, P=0.002) in preserving-remnant were superior to removing-remnant for arthroscopic anterior cruciate ligament reconstruction. These results suggest that both preserving-remnant and removing-remnant for arthroscopic anterior cruciate ligament reconstruction can obtain satisfactory antero-posterior stability of the knee. Preserving-remnant exhibits superiority in post-operative scores of the knee, proprioceptive function, tunnel enlargement. Further high-quality randomized controlled trials are warranted because of some low-quality studies and the existing biases. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程     

保留残端与不保留残端重建前交叉韧带腱骨愈合情况比较

BACKGROUND: Reconstruction with remnant preservation can enhance tendon-bone healing. However, the study limits on the histological level, and there is a lack of research based on the modular biological level. OBJECTIVE: To investigate whether anterior cruciate ligament reconstruction with remnant preservation can enhance tendon-bone healing. METHODS:Seventy-two New Zealand rabbits were randomly allocated to three groups (n=24 per group), followed by cruciate ligament reconstruction without remnant (group A), with remnant preservation (femoral tensioning and augmented suture) (group B) and with remnant preservation (graft passing remnant anterior cruciate ligament sheath) (group C), respectively. RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that the tendon-bone healing in the groups B and C surpassed that in the group A, and group B was better than group C. Real-time PCR revealed that the expression level of osteoprotegrin mRNA and the osteoprotegrin/receptor activator of nuclear factor-κB ligand (RANKL) ratio were greater in the groups B and C than in the group A, and highest in the group C, while the expression levels of RANKL mRNA in the groups B and C were lower than that in the group A. In conclusion, these two kinds of anterior cruciate ligament reconstruction methods with remnant preservation can enhance tendon-bone healing, which have obtained most obvious achievements in the anterior cruciate ligament reconstruction in the graft passing anterior cruciate ligament remnant sheath that may be related to the up-regulation of osteoprotegrin mRNA and down-regulation of RANKL mRNA. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程

膝前交叉韧带损伤后垂直起跳能力评价：运动力学指标的有效性

BACKGROUND: Evaluation of vertical jumping ability is usually only limited to height measurements. The measurements of parameters that describe kinetic factors may provide a better assessment of a patient’s jumping ability. OBJECTIVE:To determine the deficit in one-legged vertical jumping ability and to clarify the relationships between the maximum jumping height and the maximum power, force and velocity during one-legged vertical jumps after anterior cruciate ligament reconstruction. METHODS: Twenty-five healthy subjects (10 males and 15 females) and 25 anterior cruciate ligament reconstructed patients (10 males and 15 females) participated in this study. The isokinetic quadriceps femoris strength and one-legged vertical jumping ability were evaluated by the height, power, force and velocity in all subjects. RESULTS AND CONCLUSION:(1) The maximum height of the one-legged vertical jumps was only significantly correlated with the maximum force in the healthy subjects (P < 0.05). (2) However, for the reconstructed and unreconstructed legs in anterior cruciate ligament reconstructed patients, the maximum jumping height was significantly correlated with the maximum power, force and velocity during one-legged vertical jumps (P < 0.05). (3) These findings suggest the importance of a knee strategy during one-legged vertical jumps for rehabilitation after anterior cruciate ligament reconstruction. Assessment of the jumping ability after anterior cruciate ligament reconstruction may be determined by the maximum power instead of the maximum jumping height. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程     

Transphyseal reconstruction of the anterior cruciate ligament using hamstring autograft in skeletally immature adolescents

Eleven skeletally immature adolescents underwent anterior cruciate ligament reconstruction using a transphyseal tibial and femoral tunnel. An autologous quadrupled hamstring tendon was used in all cases and the average follow-up was 77.7 months. Clinical results were evaluated using Lysholm knee scores and a return to pre-injury sports activities. Radiological results were evaluated using side-to-side differences of instrumented laxities and growth disturbances compared with the uninjured side on final follow-up orthoroentgenograms. The mean Lysholm score was 97.8 (range 94-100) and mean side-to-side laxity difference was 2.4 mm (range 1-4). Ten of 11 patients returned to pre-injury sports activity. No patient had a leg length discrepancy of over 1 cm or a significant abnormal angular deformity of the knee joint. Therefore, anterior cruciate ligament reconstruction using the transphyseal tunnel and hamstring autograft in skeletally immature adolescents is believed to be a reliable treatment method, which is not associated with significant leg length discrepancy or abnormal angular deformity of the knee joint.     

带血管蒂髌韧带修复前交叉韧带损伤：计算机导航辅助关节镜的应用

BACKGROUND: The standard angle between the coronal level of tibial tunnel and the joint surface is 65°-70°. The larger angle is easy to cause impacts, and inversely, the medial joint surface of the tibia plateau will be worn. OBJECTIVE: To investigate the application and effects of patellar ligament with vascular pedicle for anterior cruciate ligament reconstruction under computer assisted navigation system combined with arthroscopy. METHODS: Forty patients with anterior cruciate ligament injury were selected, and randomly allotted into two groups (n=20 per group). Patients in traditional surgery group underwent reconstruction by the operator’s experiences, and patients in combination surgery group received the patellar ligament with vascular pedicle for anterior cruciate ligament reconstruction under computer assisted navigation system combinied with arthroscopy, both based on the same location standard. Subsequently, patients underwent CT continuous CT scans, and the tibial tunnel of anterior cruciate ligament was measured to compare the reconstruction effects. RESULTS AND CONCLUSION: The tibial tunnel and femoral tunnel positions in the combination surgery group were significantly higher than those in the traditional surgery group (P < 0.05). The Lysholm scores in the combination surgery group were significantly higher than those in the traditional surgery group at 3, 6 and 12 months after surgery (P < 0.05). Compared with the traditional surgery group, the number transmission times was significantly decreased in the combination surgery group (P < 0.05). Furthermore, sagittal CT and three-dimensional CT results showed that, in the combination surgery group, the posterior wall of the tibial tunnel closely adhered to the rear cortical bone of the proximal tibia with a distance of < 2 mm; a mild rupture appeared at the posterior wall excit of the 1/3 proximal tunnel in traditional surgery group. These results suggest that anterior cruciate ligament reconstuction under computer assisted navigation system combined with arthroscopy achieves satisfactory effects on location of the femoral tunnel. The use of navigation virtual probe avoids the subjective location by surgeons; therefore, it is feasible for clinical treatment. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程     

前交叉韧带断裂和重建的临床流行病学分析

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is the primary treatment method for ACL rupture. Currently, studies on ACL reconstruction involve histology and embryology, anatomical structure, biomechanics, reconstruction materials, operating technology, and rehabilitation after reconstruction. However, clinical epidemiological studies describing ACL rupture and reconstruction remain scarce. OBJECTIVE: To analyze the clinical epidemiological characteristics of ACL rupture and reconstruction to provide guidance for prevention and treatment of ACL rupture. METHODS: Data of 352 patients for age, gender, cause and mechanism of injury, treatment time, and the impact of ACL rupture on menisci and articular cartilage were gathered. Meanwhile, the events during surgery, operation methods and reconstruction materials were analyzed. RESULTS AND CONCLUSION: ACL rupture mostly occurred in young men, and happened more often to the left knee; male patients got hurt in basketball, football and accidental injuries, while female patients got hurt in the accidental injuries, badminton and skiing injuries, internal rotation with valgus stress accounted for the predominant injury mechanism. The ACL reconstruction was mostly performed within 1-3 months after ACL rupture, often accompanied by meniscal and articular cartilage damage. Lateral meniscus injury incidence was relatively stable, medial meniscus injury incidence increased significantly over the half year after ACL rupture. Most articular cartilage injury occurred to patellar cartilage. A significant increase in medial condylar cartilage damage over 1 year after ACL rupture was often observed. Anatomic single-bundle ACL reconstruction was the primary surgical approach, the resident ridge and the lateral bifurcate ridge could be used to position bone tunnel and autogenous semitendinosus and gracilis tendon were the most commonly used reconstruction materials. Our results indicate that anatomic ACL reconstruction should be performed as early as possible in restore knee joint stability and prevent secondary injury of the medial meniscus and cartilage of medial femoral condyle. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程     

关节镜下自体肌腱单双束重建后交叉韧带：前瞻性队列研究

背景：有研究认为后交叉韧带损伤在临床疗效上双束重建法并没有表现出其应有的优势,且较单束重建有一些难以克服的缺陷。双束与单束重建孰优孰劣？目前学界还没有给出一个统一的答案。 目的：应用前瞻性队列研究探讨自体肌腱单双束重建后交叉韧带的疗效和安全性。 方法：后交叉韧带损伤患者81例,按照随机数字表法分为单束重建组41例,双束重建组40例。对比两组患者韧带重建前、重建后24个月关节稳定性、Lysholm及Tegner评分,并比较两组患者住院天数、手术时间、重建后发热天数及需要穿刺的数量。 结果与结论：双束重建组患者移动度显著高于单束重建组(F=4.362,P=0.000);两组患者重建后24个月Lysholm及Tegner评分较重建前均有显著提高(P < 0.05),但重建前及重建后24个月两组之间差异无显著性意义(P > 0.05)。双束重建组患者手术用时及住院天数及重建后需要行关节腔穿刺的患者数均显著高于单束重建组(P < 0.05)。结果说明关节镜下单双束重建均是治疗后交叉韧带损伤的安全有效的方法,但是双束重建用时长、创伤大,不建议作为首选的修复方式。
