Anterior Shoulder Stabilization Using Single Needle-Assisted Outside-In Remplissage Technique and Bankart Repair.

Arthroscopic repair of Bankart injury is the first choice for the treatment of anterior shoulder instability. How to avoid recurring shoulder joint dislocation is a challenge, especially when combined with Hill-Sachs lesions. The arthroscopy technology allows for broader vision and less surgical trauma but is limited by a smaller operating space. At present, extensive descriptions about the surgical procedure of arthroscopic Bankart repair have been published. In this Technical Note, we describe the use of remplissage filling with Hill-Sachs lesion combined with Bankart repair to further improve the surgical accuracy and clinical efficacy. In particular, the application of single needle-assisted outside-in remplissage technique and Bankart repair is introduced in detail.

Which horticultural activities are more effective for children's recovery from stress and mental fatigue? A quasi-experimental study.

Introduction: Studies have established the benefits of horticultural therapy and activities for human health and well-being. Nonetheless, limited research has been conducted on the potential restorative advantages and distinctions between different types of horticultural activities in terms of stress reduction. Methods: This study employed a quantitative research method to investigate the stress recovery benefits of five horticultural activities (flower arrangement, sowing and transplanting seeds, kokedama crafting, pressed flower card making, and decorative bottle painting with dried flowers) and one reference activity (short composition writing) for children. The experiment was conducted in a children's activity center's multi-purpose classroom with 48 elementary students aged 9-12 years. The subjects first took a stress test to induce stress and then engaged in horticultural activities for 20 min. Physiological stress was assessed using electrocardiograms and electroencephalograms as feedback indicators. Psychological and emotional changes were determined using the Positive and Negative Affect Schedule for Children and Self-Assessment Manikin scales. Results: The results demonstrated that horticultural activities greatly reduced physiological fatigue, and their recovery benefits were significantly greater than those of the reference activity. The recovery effects from different horticultural activities were similar across physiological indicators, although flower arrangement and sowing and transplanting seeds exhibited relatively robust recovery benefits. The heart rate and α-EEG-based generalized estimating equation revealed that horticultural activities offered significantly better relative recovery at each time phase of operation than the reference activity, with girls showing a 3.68% higher relative recovery value than boys. Flower arrangement and kokedama crafting offered better physiological recovery for students with prior horticultural experience, and these two activities received the highest scores in terms of positive effects and the "pleasure" dimension. Students believed that participating in horticultural activities resulted in a noteworthy increase in personal confidence and a greater sense of achievement. Conclusion: The study suggests that horticultural activities that involve real and vibrant plants or natural materials and are more attractive have more stress-relieving benefits. We conclude that horticultural activities are beneficial leisure activities that aid in stress relief for children and that it is important to consider the attributes of activities when developing horticultural programs for elementary students.

Physeal-Sparing, All-Inside Anterior Cruciate Ligament Reconstruction Using Quadrupled Semitendinosus Autograft and Suture Tape Augmentation for Skeletally Immature Patients.

The anterior cruciate ligament (ACL) is the primary soft-tissue structure for anterior stabilization of the knee and is one of the most frequently injured structures. The incidence of ACL injuries in children and adolescents ranges from 92 to 151 per 100,000 person-years. The choice of surgical treatment for this population group is controversial, with a widespread concern that adult reconstruction techniques may damage the epiphyseal plate, compromise growth, or cause deformity. In this article, we describe a physeal-sparing, all-inside ACL reconstruction technique for skeletally immature patients. This technique is supported by retrograde drilling of the femoral tunnel and retrograde drilling of the tibial tunnel, both of which are able to avoid the epiphyseal growth line. Fixation of the quadrupled semitendinosus autograft and suture tape augmentation are achieved by soft-tissue buttons on the femur and tibia. The surgical details of this reproducible reconstruction technique are elaborated.

Appropriate thromboprophylaxis strategy for COVID-19 patients on dosage, antiplatelet therapy, outpatient and post-discharge prophylaxis: a meta-analysis of randomized controlled trials.

BACKGROUND: There was controversy surrounding the optimal thromboprophylaxis strategy for COVID-19 patients. This included debates on the dosage of anticoagulants for thromboembolism prophylaxis, the requirement for additional antiplatelet therapy, and the necessity of prophylaxis for outpatients and post-discharge. To explore this, we performed a meta-analysis of randomized controlled trials. METHODS: PubMed, Cochrane Library, Embase, and Web of Science were last searched on 26 July 2023 for studies comparing the effect of different dose of anticoagulation, additional antiplatelet and post-discharge prophylaxis for COVID-19 patients. The results of eligible studies were analyzed in terms of thromboembolism events, major bleeding and all-cause mortality during follow-up. RESULTS: Our study included a total of 25 randomized controlled trials, involving 17,911 patients. Our results revealed that, compared to prophylactic dose, therapeutic dose showed lower thrombotic risk (RR, 0.66; 95%CI, 0.45 to 0.96) but had similar major bleeding risk for critically ill patients with COVID-19. On the other hand, intermediate dose and prophylactic dose demonstrated similar thromboembolism risk and major bleeding risk. For non-critically ill patients with COVID-19, therapeutic dose of anticoagulants was associated with lower thrombotic risk (RR, 0.50; 95%CI 0.34 to 0.72) but, at the same time, increased the risk of major bleeding (RR, 2.01; 95%CI 1.22 to 3.33). However, intermediate dose showed lower thromboembolism risk (RR, 0.38; 95%CI 0.21 to 0.69) while maintaining a similar major bleeding risk. In critically ill patients, additional antiplatelet therapy showed similar thromboembolism, major bleeding risk, and mortality when compared to no treatment. For outpatients, additional prophylactic anticoagulation showed similar thromboembolism, major bleeding risk, and mortality when compared to no treatment. For post-discharge patients, post-discharge prophylaxis reduced thromboembolism risk (RR, 0.49; 95%CI 0.31 to 0.76) but increased major bleeding risk (RR, 2.63; 95%CI, 1.13 to 6.14). CONCLUSION: For non-critically ill patients, therapeutic dose prophylactic anticoagulation significantly reduced venous thromboembolism but increases major bleeding risk. Intermediate dose effectively lowered venous thromboembolism without raising major bleeding risk. The optimal dose and need for additional antiplatelet therapy in critically ill patients, as well as the necessity of prophylactic anticoagulation in outpatient and post-discharge patients, required further investigation and confirmation through rigorous evidence studies.

Evaluation of ChatGPT in providing appropriate fracture prevention recommendations and medical science question responses: A quantitative research.

Currently, there are limited studies assessing ChatGPT ability to provide appropriate responses to medical questions. Our study aims to evaluate ChatGPT adequacy in responding to questions regarding osteoporotic fracture prevention and medical science. We created a list of 25 questions based on the guidelines and our clinical experience. Additionally, we included 11 medical science questions from the journal Science. Three patients, 3 non-medical professionals, 3 specialist doctor and 3 scientists were involved to evaluate the accuracy and appropriateness of responses by ChatGPT3.5 on October 2, 2023. To simulate a consultation, an inquirer (either a patient or non-medical professional) would send their questions to a consultant (specialist doctor or scientist) via a website. The consultant would forward the questions to ChatGPT for answers, which would then be evaluated for accuracy and appropriateness by the consultant before being sent back to the inquirer via the website for further review. The primary outcome is the appropriate, inappropriate, and unreliable rate of ChatGPT responses as evaluated separately by the inquirer and consultant groups. Compared to orthopedic clinicians, the patients' rating on the appropriateness of ChatGPT responses to the questions about osteoporotic fracture prevention was slightly higher, although the difference was not statistically significant (88% vs 80%, P = .70). For medical science questions, non-medical professionals and medical scientists rated similarly. In addition, the experts' ratings on the appropriateness of ChatGPT responses to osteoporotic fracture prevention and to medical science questions were comparable. On the other hand, the patients perceived that the appropriateness of ChatGPT responses to osteoporotic fracture prevention questions was slightly higher than that to medical science questions (88% vs 72·7%, P = .34). ChatGPT is capable of providing comparable and appropriate responses to medical science questions, as well as to fracture prevention related issues. Both the inquirers seeking advice and the consultants providing advice recognize ChatGPT expertise in these areas.

Similar outcomes between arthroscopic capsular release and manipulation under anaesthesia for frozen shoulder: A meta-analysis.

To compared the arthroscopic capsular release (ACR) with manipulation under anaesthesia (MUA) for the surgical treatment of frozen shoulder (FS) based on postoperative outcomes and complications. PubMed, Cochrane Library, Embase, and Web of Science were searched on October 2, 2023 to retrieve eligible studies that compared ACR with MUA in terms of clinical outcomes (pain visual analogue scale, external rotation, forward flexion and adverse events) for patients with FS. Mean differences (MD) were calculated for continuous outcomes and odds ratios (OR) were calculated for dichotomous outcomes. Six papers, including 5 clinical studies (a total of 690 shoulders), were included in the final meta-analysis. The forward flexion was found to be larger in the ACR group at 3 months (MD, 2.73; 95%CI, 0.42-5.04; I2 = 44%; P = 0.02) and 6 months (MD, 2.36; 95%CI, 1.29-3.44; I2 = 0%; P < 0.0001). Except for this, ACR was comparable with MUA in terms of pain visual analogue scale at 3, 6 and 12 months (p = 0.25, p = 0.11, p = 0.28, respectively), external rotation at 3, 6 and 12 months (p = 0.15, p = 0.52, p = 0.23, respectively), and forward flexion at 12 months (p = 0.08). There were no differences in complication rates between the two groups (OR, 0.82; 95%CI, 0.47-1.44; I2 = 0%; P = 0.50). In comparison with MUA, ACR demonstrated better outcomes for forward flexion at 3 and 6 months, while there were no significant differences between ACR and MUA in terms of pain visual analogue scale, external rotation and adverse events.

Long-term effects of exercise therapy versus arthroscopic partial meniscectomy for degenerative meniscal tear: A meta-analysis of randomized controlled trials.

BACKGROUND: Degenerative meniscal tear (DMT) is common in the elderly population. However, there has been controversy over the treatment of DMT regarding whether to adopt arthroscopic partial meniscectomy (APM) or exercise therapy (ET). In order to compare the long-term outcomes between the two treatment methods, we conducted a meta-analysis of randomized controlled trials (RCTs) with long-term follow-up. METHODS: PubMed, Cochrane Library, Embase, and Web of Science were last searched on 16 April 2023 for studies on DMT that compared the clinical outcomes between APM and ET. The subjective outcomes of the comparison include the Knee Injury and Osteoarthritis Outcome Score (KOOS), which consists of five sub-scales: pain, symptoms, activities of daily living (ADL), sport and recreation (Sport/recreation), and quality of life (QOL). The objective outcome includes knee osteoarthritis progression. RESULTS: We identified 6 potentially eligible trials, including 1078 participants, from the literature search. ET showed a lower risk of knee osteoarthritis progression than APM (RR, 1·27; 95%CI 1·05 to 1·53). There were no statistically significant differences in the KOOS-pain, KOOS-symptoms, KOOS-ADL, KOOS-Sport/recreation, and KOOS-QOL between the two treatment methods. CONCLUSION: For the treatment of DMT, ET showed a lower risk of knee osteoarthritis progression than APM. ET and APM had comparable effects on subjective outcomes including pain management and knee function. Therefore, it is not recommended to use APM but rather recommended to use ET for treating APM.

Interposition Grafting Using Fascia Lata Autograft for Failed Rotator Cuff Repairs.

Massive rotator cuff tears are a huge challenge for orthopaedic surgeons, as the patients may be in need of multiple operations, even including reverse total shoulder arthroplasty. The various repair methods for the rotator cuff, such as partial rotator cuff repair, patch-augmented rotator cuff repair, bridging rotator cuff reconstruction with graft interposition, tendon transfer, and superior capsular reconstruction, have always been the focus of research. During surgical intervention for failed rotator cuff repairs, complexity of tears, poor tissue quality, retained hardware, and adhesions are the problems routinely encountered. In this Technical Note, we describe the technique of interposition grafting using fascia lata autograft to reconstruct the rotator cuff after failed primary repair.

Preferences in anterior cruciate ligament reconstruction: A survey among orthopedic surgeons in China.

The purpose of this study was to reveal the current trends and preferences of Chinese orthopedic surgeons regarding anterior cruciate ligament (ACL) reconstruction through a nationwide web-based survey conducted in China. The survey questionnaire was distributed via WeChat to the chairmen of provincial orthopedic and sports medicine organizing committees in China, who then shared it in their respective WeChat workgroups. The questionnaire consisted of 52 multiple-choice questions covering 8 sections. Data collection was implemented by Questionnaire Star. A total of 812 valid questionnaires were returned: 94.21% of the respondents preferred single-bundle reconstruction of ACL, while 61.70% preferred autogenous semitendinosus plus gracilis reconstruction; 76.35% of the respondents preferred establishing the femoral tunnel first, while 47.29% preferred establishing the femoral tunnel through a medial auxiliary approach; and 85.10% of the respondents recommended patients to undergo surgery within 3 months after ligament injury. Besides, the vast majority of respondents chose to retain the ligamentous remnant bundle (92.98%) and recommended routine use of knee braces postoperatively (94.09%). It is recommended to perform arthroscopic single-bundle ACL reconstruction with the remnant preserving technique using a hamstring autograft within 3 months of ACL rupture, with support of postoperative functional braces.

How to predict the dimensions of anterior cruciate ligament in children based on MRI?

There are many studies examining the dimensions of the anterior cruciate ligament (ACL) in children. The correlations between the ACL size in children and other parameters are not well understood. To detect the correlations between the ACL size in children and other parameters including age, gender, bone and soft tissue parameters through measurements on MRI images, and to establish prediction models for the ACL size. A total of 99 patients who underwent MRI scan were included (39 girls, 60 boys; mean age, 13.01 ±â€…3.94; range of age, 4 to 18). The following measurements were taken on MRI images by 2 observers: ACL length, ACL width, posterior cruciate ligament (PCL) length, the distance from the most anterior aspect of the tibial epiphysis to the anterior aspect of the ACL tibial insertion (AATI), the distance from the most anterior aspect of the tibial epiphysis to the posterior aspect of the ACL tibial insertion (APTI), and the tibial anteroposterior diameter (AP). Correlations between these measurements and the patients' gender and age were investigated, and univariate and multiple linear regression models were established accordingly. Before 13 years old, the ACL length was significantly correlated with the tibial anteroposterior diameter and age (R2 = 0.872, P < .001), and there were no statistically significant gender differences. After 13 years old, the ACL length was significantly correlated with the PCL length and APTI in males (R2 = 0.443, P < .001), and with the PCL length in females (R2 = 0.443, P < .001). In children under 13 years old, there was no significant gender difference in ACL length, and the tibial anteroposterior diameter and age were found to be important indicators in assessing the ACL size. After 13 years old, a significant gender difference in ACL length was observed, and the ACL length was found to be weakly correlated with age and bone parameters. In order to accurately evaluate the ACL size in children aged 13 years and above, it is necessary to refer to the dimensions of the ACL on the collateral side.

Reliability of the Tibial Spine Versus ACL Stump in Assisting Tibial Tunnel Positioning During ACL Reconstruction: Analysis Based on 3-Dimensional Computed Tomography Modeling.

Background: Several techniques have been used by surgeons for anatomic tibial tunnel placement in anterior cruciate ligament (ACL) reconstruction, including the ACL stump positioning (ASP) technique and the tibial spine positioning (TSP) technique. Purpose/Hypothesis: The purpose of this study was to evaluate whether bony landmarks (medial and lateral tibial spine [MLTS]) can be a reliable reference for improving the accuracy of tibial tunnel placement in anatomic single-bundle ACL reconstruction compared with the ACL stump. It was hypothesized that the MLTS would not be a reliable bony landmark for tibial tunnel placement. Study Design: Cohort study; Level of evidence, 3. Methods: The 3-dimensional computed tomography images of 111 patients who underwent ACL reconstruction between 2020 and 2021 were included in this study. For tibial tunnel placement, the ASP technique was used in 49 patients, and the TSP technique was used in 62 patients. The 3-dimensional computed tomography images were reconstructed to enable measurements of the locations of the MLTS and tunnel center based on a grid method. Statistical analysis was conducted to compare the MLTS location and tibial tunnel position as well as the accuracy (mean distance of each actual location from the anatomic center) and precision (standard deviation of the accuracy, indicating the reproducibility of the tunnel position) of the tunnel position between the ASP and TSP groups. Results: Significant differences were observed between the ASP and TSP groups in terms of the tibial tunnel position on the mediolateral axis (46.7% ± 2.0% vs 45.9% ± 2.2%, respectively; P = .034), while no significant differences were found in terms of the accuracy (4.1% vs 4.6%, respectively; P = .259) or precision (2.1% vs 2.1%, respectively; P = .259) of tibial tunnel positioning between the 2 groups. Conclusion: In anatomic single-bundle ACL reconstruction, the use of the MLTS for tibial tunnel placement achieved comparable accuracy and precision compared with the use of ACL remnants, supporting its role as a reliable bony landmark in tibial tunnel positioning.

The role of vitamin D in the prevention and treatment of SARS-CoV-2 infection: A meta-analysis of randomized controlled trials.

BACKGROUND: Vitamin D (VitD) has been shown to be important for the immune response of the respiratory system, but the preventive and therapeutic effects of vitamin D supplementation on SARS-CoV-2 infection are controversial. This study aimed to determine the role of vitamin D supplementation in the prevention and treatment of SARS-CoV-2 infection through a meta-analysis of randomized controlled trials. METHODS: The databases of PubMed, Cochrane Library, Embase, Web of Science and Google Scholar were searched systematically from inception to April 17,2023 to identify trials involving a randomized comparison of vitamin D supplementation versus non-vitamin D supplementation for SARS-CoV-2 infection prevention or treatment. RESULTS: We retrieved 25 eligible trials, including 8128 participants. Four trials compared the preventive effects of vitamin D supplementation on SARS-CoV-2 infection, and the results (RR 0.31; 95%CI 0.07 to 1.32) were inconclusive. Regarding the treatment of SARS-CoV-2 infection with vitamin D supplementation, it was found that vitamin D supplementation could significantly reduce the rates of ICU admission (RR 0.63; 95%CI 0.44 to 0.89) and mechanical ventilation (RR 0.58; 95%CI 0.39 to 0.84), but had no statistically significant effect on mortality. However, in subgroup analyses based on the patients' specific conditions, vitamin D supplementation significantly reduced the mortality in patients with vitamin D deficiency (RR 0.76; 95%CI 0.58 to 0.98). CONCLUSION: Vitamin D supplementation may have some beneficial impact on the severity of illness caused by SARS-CoV-2, particularly in VitD deficient patients, but further studies are still needed.

Surgical considerations for glenoid bone loss in anterior glenohumeral instability: a narrative review.

PURPOSE: Treatment algorithms may consider many factors like glenoid and humeral bone loss, or scores such as the instability severity index score (ISIS). As most studies only evaluate a part of these factors, there is still no evidence-based consensus estalished. Our study aims to summarize the surgical options for treatment of glenoid bone loss (GBL) in anterior shoulder instability. METHODS: Based on the current available literature, surgical options including Bankart repair and glenoid bone augmentation should be considered while taking into consideration the degree of bone loss which has been divided into < 10%, 10-20% and > 20%. RESULTS: There are many new techniques evolving including arthroscopic anatomic glenoid reconstruction with bone blocks. CONCLUSION: Future long-term outcome studies and randomized controlled trials comparing established techniques will be needed for new evidence-based treatment algorithms.

The role of aspirin versus low-molecular-weight heparin for venous thromboembolism prophylaxis after total knee arthroplasty: a meta-analysis of randomized controlled trials.

BACKGROUND: There is a debate over the use of aspirin after total knee arthroplasty (TKA) for venous thromboembolism (VTE) prophylaxis. To evaluate the clinical effectiveness and safety of aspirin after TKA, the authors performed a meta-analysis of randomized controlled trials that compared aspirin with low-molecular-weight heparin (LMWH). METHODS: PubMed, Cochrane Library, Embase, and Web of Science were last searched on 31 January 2023 for studies comparing the effect of VTE prophylaxis between aspirin and LMWH. The results of eligible studies were analyzed in terms of VTE, deep venous thrombosis, pulmonary embolism, and bleeding complications rates. RESULTS: Six randomized controlled trials including 6772 patients met the inclusion criteria. LMWH showed a statistically significant reduction in the overall VTE rate (RR 1.46, 95% CI: 1.16-1.84). No significant differences in deep venous thrombosis, pulmonary embolism, and bleeding complications rates were found between aspirin and LMWH. CONCLUSION: Compared with LMWH, aspirin presents a higher risk of VTE after TKA. In terms of safety, aspirin and LMWH show comparable outcomes. The results do not support the role of aspirin role as an anticoagulant for preventing VTE after TKA.
