Anterior cruciate ligament (ACL) reconstruction yields favorable outcomes for restoring anteroposterior stability of the knee joint in patients with ACL tears. However, some patients still exhibit positive knee pivot shift after ACL reconstruction. Currently, combined ACL and anterolateral ligament(ALL) reconstruction has been accepted by most scholars. This surgical technique can restore the rotational stability of the knee joint in patients postoperatively and facilitate the early besumption of sports training after surgery. This article reviews the anatomical research, isometry-like point research, and reconstruction indications of the anterolateral ligament, as well as the surgical approaches, graft tunnel convergence, and reconstruction outcomes of combined anterior cruciate ligament and anterolateral ligament reconstruction.

This paper summarized the key points and methods in terms of the establishment of the guideline working group and the management of conflict of interests， trying to provide reference for the development of clinical practice guidelines for Chinese patent medicine （CPM）. The establishment of the working group is the first important step for developing CPM guidelines. Considering the characteristics of the clinical practice guidelines for CPM， this study suggests that the three key elements of ‘multidisciplinarity’， ‘clinical relevance’ and ‘geographical representativeness’ should be put focus on when forming the working group. The guideline advisory committee， clinical expert group， evidence systematic evaluation group， secretary group and the external review group should be established. All group members should clarify the conflict of interest， and the process and management method of the conflict of interest should be clearly reported.

Recommendations for Chinese patent medicine （CPM） based on key information on rational drug use are one of the important conditions for enhancing guideline enforceability as well as facilitating guideline implementation. In this study， we discussed in detail of the key information on the rational use of CPM in five aspects， which are dosage， drug discontinuation， drug-drug and drug-food interactions， safety and economy. Following the process of multi-source search， synthesis and prioritization， it is suggested to collect key information on the rational use of CPM from a multi-source search of drug instructions， policy documents， literature， and clinical experts' experiences. Then the searched information should be summarized and prioritized with the principle that taking drug instructions as the basis and other-sources information for check and supplementation. Finally， methodological recommendations for the retrieval and synthesis of key information on rational drug use in guideline recommendations has been formed.

Obiective:To explore the surgical technique of arthroscopic reconstruction of the anterior cruciate ligament (ACL) combined with anterior lateral ligament (ALL) using the hamstring tendon graft through the femoral tunnel, and evaluate the clinical efficacy before and after surgery.Methods:Retrospective analysis of clinical data of 20 patients with ACL combined with ALL rupture admitted to Qinhuangdao First Hospital of Hebei Medical University from October 2020 to July 2022. All patients received arthroscopic reconstruction of ACL combined with ALL using the hamstring tendon graft through the femoral tunnel. The Lysholm knee joint score, International Knee Documentation Committee (IKDC) score, and Lachman test were evaluated using a questionnaire survey, and objective evaluations were performed using a knee joint activity measurement instrument and a KT-2000 measurement instrument before and 1 year after surgery. Compare the Lysholm knee joint score, IKDC score, Lachman test grade, knee flexion and extension range of motion, and tibia anterior and posterior relaxation before and after surgery. The measurement data were represented by mean ± standard deviation ( ± s), and t-test was used for comparison before and after surgery. The comparison of paired grade data before and after surgery was conducted using Wilcoxon test. Results:All 20 patients underwent surgery successfully, and all patients were followed up for an average follow-up time of (12.2±1.4) months, with a surgical time of 60-90 minutes. Postoperative MRI examination of the knee joint showed good graft fixation and no common complications such as knee stiffness, infection, deep vein thrombosis, and neurovascular injury. At the last follow-up, the knee joint flexion and extension activities of 20 patients were normal, with 2 patients weakly positive for Lachman test I; the Lysholm knee joint score and IKDC score increased from preoperative (44.6±1.7) points and (54.2±2.0) points to final follow-up (87.5±1.3) points and (89.6±1.0) points, respectively. The knee joint flexion and extension range of motion increased from preoperative (35.0±1.5)°to final follow-up (134.2±2.5)°, and the knee joint stability and function score improved significantly compared to preoperative, and the difference was statistically significant ( P<0.05); bend the knee 90°, KT-2000 measures the difference in tibial relaxation decreased from preoperative (11.9±1.0) mm to final follow-up (1.9±0.3) mm. The results showed that the stability of the knee joint was significantly improved compared to before surgery, and the difference before and after surgery was statistically significant ( P<0.05). Conclusions:The surgical technique of arthroscopic reconstruction of ACL and ALL using a single bundle of hamstring tendon graft under knee arthroscopy is safe and effective, and can restore the stability of knee joint rotation in patients. The clinical subjective and objective functional scoring indicators for short-term follow-up after surgery are satisfactory.
