Résumé
Anterior cruciate ligament (ACL) injury is a common sports injury of the knee joint, which can lead to knee instability, dyskinesia and secondary traumatic osteoarthritis, which seriously affects the quality of life of patients. As it is difficult to self-heal after ACL injury, arthroscopic ACL reconstruction is commonly used as a clinical treatment to restore knee stability and motion function. However, more and more studies have found that bone tunnel enlargement is common after ACL reconstruction. A variety of biological (such as immunological rejection, local inflammation) and mechanical (such as offset bone tunnel positioning, improper graft fixation, and aggressive rehabilitation) factors are considered to be important causes of bone tunnel enlargement. It is still controversial whether the enlargement of bone tunnels affects clinical outcomes, but most researchers believe that the enlargement of bone tunnels is detrimental to the creation of bone tunnels and the fixation of grafts in revision surgery. Therefore, minimizing postoperative bone tunnel enlargement has positive clinical implications. The existing methods mainly include the selection of autografts, the use of independent bone tunnel positioning technology, modified bone tunnel drilling method, the use of remnant preservation technique and all-inside technique, the development of progressive individualized rehabilitation programs, and biological methods such as platelet-rich plasma and autogenous periosteum wrapping graft to enhance graft tendon-bone healing. This article reviews the causes and countermeasures of bone tunnel enlargement after ACL reconstruction to provide theoretical basis and help reduce or avoid bone tunnel enlargement after ACL reconstruction.

The anterior cruciate ligament (ACL) is one of the most crucial components to maintain knee joint stability and also the most vulnerable structure during knee-related sports activities. ACL injuries often cause knee instability, difficulty in returning to sports, and secondary degenerative knee disease. Although using autograft to reconstruct the ACL is currently a popular choice in clinical settings, it has drawbacks such as limited autograft source, donor site morbidity and delayed return to sports. Ligament advanced reinforcement system (LARS) artificial ligament possesses unique advantages such as wide availability, no donor-site morbidity, and early recovery, avoiding the problems associated with autograft reconstruction of ACL, and it has drawn increasing attention in recent years. In this paper, the authors reviewed the characteristics of LARS artificial ligament and its application in ACL reconstruction, so as to provide reference for clinical treatment of ACL injuries.

Objective:To explore the role of navigation-assisted valgus stress method in avoiding excessive correction of lower limb mechanical axis after high tibial osteotomy (HTO).Methods:A retrospective study was carried out on osteoarthritis (OA) patients who were treated with HTO for medial compartment pain of knee from January 2020 to March 2022 in the Department of Joint Surgery, Shanghai Changhai Hospital, the First Affiliated Hospital of Naval Medical University. According to the different ways of confirming alignment during operation, they were divided into computer navigation assisted valgus stress HTO group (referred to as navigation group) and traditional rod fluoroscopy HTO group (referred to as traditional group). There were 28 patients in the navigation group, 10 males and 18 females, with age of 54.4±9.1 years (range, 41-73 years) and body mass index of 26.1±3.3 kg/m 2 (range, 19.8-35.2 kg/m 2); There were 30 patients in the traditional group, 13 males and 17 females, aged 56.9±8.5 years (range, 40-70 years), with a body mass index of 25.7±4.0 kg/m 2 (range, 19.2-32.9 kg/m 2). Measuring the mechanical femoral tibial angle (mFTA), joint line convergence angle (JLCA), medial proximal tibial angle (MPTA), Lysholm score and Hospital for Special Surgery (HSS) score before operation and at the last follow-up of the two groups, and conduct statistical analysis. Results:Both groups were followed up. The follow-up time of navigation group and traditional group was 21.3±8.7 months and 22.5±7.6 months, respectively, with no significant difference ( t=0.53, P=0.596). There were significant differences between the two groups in the amount of mechanical axis correction (ΔmFTA) and the amount of bone correction (ΔMPTA) ( t=2.09, P=0.041; t=2.58, P=0.012), while there was no significant difference in ΔJLCA ( t=0.32, P=0.753). In the navigation group, there were 9 cases (32%) of undercorrection, 17 cases (61%) with acceptable alignment, and 2 cases (7%) with over correction, while in the traditional group, there were 5 cases (17%) with under correction, 13 cases (43%) with acceptable alignment, and 12 cases (40%) with over correction. There was significant difference in the distribution rate of alignment between the two groups ( P=0.012), and the rate of overcorrection in the navigation group was significantly lower than that in the control group (7% vs. 40%, P=0.005). The intra group correlation coefficient between the navigation correction mechanical axis and ΔmFTA was 0.787. There was no significant difference in Lysholm score and HSS score between the two groups before and after surgery (all P>0.05), and they were significantly improved after operation (all P<0.05). Conclusion:Navigation-assisted valgus stress method HTO is reliable, which can accurately achieve the target alignment, reduce the incidence of over correction, and obtain good clinical results.
Résumé
Rupture of the anterior cruciate ligament (ACL) is one of the most frequent forms of knee sports injuries. Nowadays, ACL reconstruction is commonly performed to help patients restore their rotational stability. However, in patients with high risk factors, the risk of ACL reconstruction failure remains high, primarily because of continuous postoperative anterolateral rotational instability. This rotational instability after ACL reconstruction has prompted researchers to focus on the anterolateral complex of the knee, such as iliotibial tract and anterolateral ligament (ALL). Among them, ALL has remained largely unappreciated for more than a century since its discovery in 1879. Even though it is still controversial, most studies in recent years have supported the anterolateral ligament as an independent ligament and a crucial anatomical component for preserving the rotational stability of the knee joint. Although augmentation of the anterolateral complex has experienced twists and turns, the anatomic ALL reconstruction, which can be performed minimally invasively and has a low risk of complications and minimal injury, is reappearing as a key strategy to address this problem. Currently, the majority of scholars believe that the need for combined ALL reconstruction during ACL reconstruction should be taken into account when there is severe rotational instability present, such as high-grade pivot shift test preoperatively, ACL revision surgery, and high requirements for rotational stability, such as age less than 25 years and the need to participate in pivoting sports. The corresponding suggested criteria are also put forth in the authoritative consensus of both domestic and foreign sources. However, the surgical indications chosen by different experts based on their individual experiences are not all consistent. Due to conflicting reports on the actual impact of ALL reconstruction on improving rotational stability and whether it will excessively restrict knee's internal rotation function, there is still much debate among researchers regarding whether ALL reconstruction and ACL reconstruction should be combined. Currently, there are two main reconstruction techniques: ALL single bundle reconstruction and Y-construct ALL double bundle reconstruction. Y-construct ALL double bundle reconstruction has a better ability to restore the original anatomy and is recommended in the consensus, but there is still a lack of randomized controlled trials between the two techniques. Therefore, the combination of ALL reconstruction at the time of ACL reconstruction has been clinically started in recent years for patients who are susceptible to failure after ACL reconstruction, which also raises many controversies.
Résumé
Rupture of anterior cruciate ligament (ACL) is one of the most common sports injuries of the knee, which may cause limitation of motor function and degeneration of the knee, seriously affecting patients' living quality. Currently, arthroscopic ACL reconstruction (ACLR) has been identified as the gold standard for ACL rupture. In an effort to further increase surgical accuracy and decrease surgical trauma so as to promotes quick recovery, all-inside ACLR has gained increasing attention in recent years. All-inside ACLR is as effective as traditional reconstruction, but it has benefits such as the preservation of tendons, preservation of bone mass, reduction of postoperative pain, prevention of synovial fluid leakage, expansion of the tendon-bone healing area, avoidance of complications related to extrusion screws, and suitability for children and adolescents. However, applying of numerous novel techniques for all-inside ACLR increases the learning curve, operating time, and cost. Besides, improper bone tunnel fabrication and graft fixation may lead to the widening of the bone tunnel, affecting the surgical effect. Therefore, in order to provide a theoretical foundation for further promoting the clinical application of this technique, this article reviews the development, evolution, and clinical outcomes of this technique as well as its advantages and disadvantages.
Résumé
It is difficult to maintain the initial posterior stability of the knee after posterior cruciate ligament reconstruction. Residual posterior knee laxity after operation is a problem of PCL reconstruction. It not only results in abnormal kinematics of the knee, but also leads to secondary meniscus injury and cartilage degeneration of the affected knee, and eventually leads to knee osteoarthritis, which may especially happen with persistent and severe posterior laxity. The main reasons of residual posterior knee laxity after PCL reconstruction are: improper treatment of the posterolateral corner injury, poor positioning of the femoral tunnel, small tibial slope, and unreasonable postoperative rehabilitation. There are some concepts and technologies, such as using artificial ligaments, tibial tunnel fixation with suspensory device or suspensory device combined with interference screws, enlargement of graft diameter, all-inside reconstruction combined suture augmentation, slow and gradual postoperative rehabilitation, which can eliminate or reduce the postoperative residual laxity, in order to improve clinical outcomes after PCL reconstruction. For the patients with flat tibial slopes, double-bundle PCL reconstruction and concurrent slope-increasing tibial osteotomy is suggested. It can reduce the risk of posterior laxity and improve the stability of the knee after operation.
Résumé
The reconstruction of the posterior cruciate ligament (PCL) through the tibial tunnel is the most commonly used reconstruction technique after ligament injury.However, when the graft passes through the tibial tunnel back to the medial condyle of the femur, a sharp angle is formed at the proximal end of the tibia, called the "killer turn". The existence of the "killer turn" can lead to graft wear and expansion of adjacent tibial tunnel after PCL reconstruction, affecting the stability of the posterior knee joint after operation and even leading to the failure of operation. There are several techniques, such as modifified tibial tunnel technique which the proximal exit of tibial tunnel is located in the inferior and lateral aspect of the PCL tibial anatomic insertion site, increasing the angle between the tibial tunnel and the tibial plateau, creating a tibial tunnel from the anterior lateral side of the tibia, remnant preserving as soft tissue cushion, and inlay and onlay techniques for reconstructing PCL without using tibial tunnel reconstruction, can reduce the "killer turn" effect. The above 6 techniques, theoretically, can effectively reduce or eliminate the "killer turn" effect and improve the posterior stability of the knee joint after PCL reconstruction, so as to improve the clinical efficacy of PCL reconstruction. But, the number of cases using these techniques is relatively small, and their effectiveness, reliability, and advantages and disadvantages for patients still need more clinical practice to further explore and verify.

Meta-analysis showed that the graft diameter [ MD=0.42, 95% CI (0.11, 0.73), P=0.007] and International Knee Documentation Committee (IKDC) subjective score [ MD=1.11, 95% CI (0.36, 1.86), P=0.004] of the all-inside group was larger than full-tibial tunnel group, and the tibial tunnel widening of the all-inside group was less than full-tibial tunnel group [ MD=-1.70, 95% CI (-2.38, -1.01), P<0.001]. There were no significant differences in IKDC objective score [ OR=1.09, 95% CI (0.67, 1.78), P=0.730], Lysholm score [ MD=0.99, 95% CI (-0.08, 2.05), P=0.070], Tegner activity score [ MD=-0.01, 95% CI (-0.48, 0.45), P=0.950], bilateral knee anterior laxity difference [ MD=0.32, 95% CI (-0.22, 0.86), P=0.250], negative rate of pivot shift test [ OR=0.80, 95% CI (0.33, 1.91), P=0.610], graft re-rupture rate [ OR=0.76, 95% CI (0.34, 1.74), P=0.524] and return to sport rate [ OR=1.56, 95% CI (0.85, 2.86), P=0.150]. Conclusion:All-inside ACL reconstruction provides satisfactory efficacy. Compared with full-tibial tunnel technique, it has the advantages of larger graft diameter and less tibial tunnel widening, with no difference in joint function within 2 years postoperatively.

Résumé
Abstract@#Transport of filter paper-dried blood spot samples is a critical procedure during the screening of neonatal inherited metabolic diseases, which is of great significance for the screening accuracy. In order to ensure the timing and safety of sample transport, the cold chain positioning system was initiated by Zhejiang Provincial Center for Quality Control of Neonatal Disease Screening since March 2015. Based on the framework of neonatal disease screening information management system, the function of the logistics transport management system was included in this positioning system, with aims to achieve the monitoring and tracking of sample transport processes through real-time positioning of the sample transport box via China Unicom 4G logistics card and global positioning system/BeiDou Navigation Satellite System. The samples are maintained in a transport environment at 2 to 8 °C via the temperature-controlled box made of 5 °C phase-changed cold-stored materials and general packet radio service (GPRS) temperature recorders. The mean pretest turnover duration reduced from 8.44 days to 5.03 days following introduction of the cold chain positioning system, and the percentage of timely sample delivery increased from 31.69% to 77.90%, while the withdrawal rate of unqualified samples reduced from 0.12% to 0.08%. The cold chain positioning system meets the requirements of transport of filter paper-dried blood spot samples, which has a high potential in screening of neonatal inherited metabolic diseases.
