Posterior Medial Meniscus Root Tears: Clinical Implications, Surgical Management, and Post-operative Rehabilitation Considerations.
Authors: Monson Jill K. , LaPrade Robert F. 
Published: January 2025

Tears of the posterior medial meniscus root (PMMR) are common in older patients and reportedly contribute to rapid joint degeneration over time. Recognition of these tear types and the appropriate diagnosis through clinical exam and diagnostic imaging have improved significantly in recent years, as have surgical techniques to address them. Standardized post-operative rehabilitation protocols specific to PMMR repair have not been established or well understood in the scientific literature. Thus, clinicians have little guidance for managing post-operative care. Upon diagnosis of a root tear, appropriate surgical treatment, with appreciation for native anatomy and function of the meniscus root, is a critical first step for recovery. Post-operative rehabilitation protocols should account for biomechanical considerations unique to root tears, because they can destabilize the entire meniscus and compromise its native function. Rehabilitation specialists can apply known science regarding the influence of joint motion, muscle strengthening activities, gait, squatting, and progressive loading activities on the healing meniscus to guide post-operative recovery. This knowledge, complemented with existing foundational principles for sound post-operative rehabilitation, can optimize recovery for patients following PMMR repair. The purpose of this clinical commentary is to explore clinical questions related to 1) PMMR injury epidemiology, 2) diagnosis and surgical management of PMMR tears, and 3) critical considerations for safe and effective post-operative rehabilitation.

Background The United States military strives to prepare soldiers physically and mentally for war while preventing injury and attrition. Previous research has focused on physical injury risk factors but has not prospectively examined psychological risk factors. Purpose This study’s purpose was to investigate whether self-efficacy is a risk factor for musculoskeletal injury in an initial military training environment and compare it to other known risk factors. Study Design Prospective, Longitudinal Cohort Study Materials and Methods Shortly after starting cadet basic training, new cadets rated self-efficacy by an 11-point questionnaire. Other risk factor data including injury history, sex, height, weight, body mass index, age, aerobic fitness, upper body muscular endurance, core muscular endurance and previous military experience were collected by self-report questionnaire and military fitness testing. The primary dependent variable was musculoskeletal injury that originated during the seven-week course. Independent variables were compared between participants who were and were not injured using Chi-squared test, t-tests, Cox regression analysis and time to injury was evaluated using Kaplan-Meyer survival analyses. Results Seven hundred eighty-one (65.1%) new cadets were eligible and consented to participate. Injured cadets had significantly lower self-efficacy scores (p=0.003 and p=<0.001), shorter height (p=<0.001), lower weight (p=0.036), lower push-up and plank performance (p=<0.001), slower two-mile run performance (p=<0.001), and females sustained a proportionally higher number of injuries than males (p=<0.001). Cadets with low self-efficacy, shorter height, lower hand release push-up performance, lower plank performance and slower two-mile run performance were at greater risk for musculoskeletal injury. Cadets with less self-efficacy were also less likely to continue uninjured throughout cadet basic training according to a Kaplan-Meier survival analysis (log rank test<0.002). Multivariable Cox regression revealed that only aerobic fitness predicted musculoskeletal injury (HR=1.005 [1.003-1.006], p=<0.001). Conclusions Participants with less self-efficacy sustained injuries earlier and more often than those with greater self-efficacy. However, aerobic fitness alone predicted future injury after controlling for all risk factors. Resolved prior injury was not a risk factor for future injury.

Published: January 2025

Background and Purpose Anterior cruciate ligament (ACL) tears often occur due to non-contact mechanisms in landing within females. Impact loading and aberrant landings may be addressed with augmented feedback training. The purpose of this study was to identify which female athletes most readily respond to a single session of augmented feedback to attenuate vGRF, by considering baseline peak vGFR and change in vGRF during training. Design Repeated Measures Methods One hundred, forty-seven female athletes landed from 50 cm onto two force platforms with and without augmented feedback of vertical ground reaction force (vGRF), vGRF symmetry, and lower extremity position. Each performed six baseline trials and two sets of six training trials with cues. Following training, athletes completed six post-feedback trials (with no feedback) and six dual-task (transfer) trials where they randomly caught a basketball during landing. Peak vGRF was measured. Mean responses were reported for the sets of six trials. Participants were grouped based on their responses to training. Linear regression was used to indicate how well initial performance and response predicted the final response. Results Four groups were identified, with 107 participants showing high baseline ground reaction forces and response to training. Only 23 participants (16.4%) did not respond to training. Baseline vGRF predicted post-feedback vGRF and transfer task vGRF (R2=0.508 and R2=0.400) across all participants. When change in vGRF was assessed following two blocks of augmented feedback training, prediction of responders improved with post-feedback vGRF and transfer vGRF (R2=0.911 and R2=0.761). Conclusions The combination of both baseline ground reaction force and response to initial training is more accurate than baseline measures alone in identifying those who respond to training. Assessing initial response to training may be necessary to more accurately identify individuals most likely to benefit from augmented feedback training and who may require further evaluation and training.

Accuracy of Two Methods in Estimating Target Muscle Force During Shoulder Submaximal Isometric Contractions
Authors: Griech Sean F. , Karagiannopoulos Christos 
Published: January 2025

Background Submaximal isometric exercises are used for pain control and neuromuscular facilitation. Typically, an ipsilateral maximal voluntary isometric contraction (MVIC) is used as a reference; however, when this is not clinically feasible, an alternative must be considered. Two options are (1) the no reference (NR) method (submaximal contraction at a self-perceived effort level without reference) and (2) the reciprocal reference (RR) method (MVIC on the contralateral side serves as a reference for a submaximal effort-level on the ipsilateral side). No research evidence exists as to which alternative method is more accurate at the shoulder. Purpose To determine the accuracy of the NR and RR methods in estimating target muscle force during shoulder ER and IR submaximal isometric contractions among healthy adults. Study Design Observational cross-sectional Methods Isometric shoulder force was measured via a hand-held dynamometer on 48 healthy participants (36 females and 12 males) mean age of 27.4 ±1.6 years. Both methods (NR and RR), direction of force (IR and ER), and starting test-side (right or left) were randomized. RR testing involved a contralateral MVIC (reference) prior to a 50% submaximal contraction. NR testing entailed a 50% submaximal contraction with no prior reference MVIC. Results Actual submaximal efforts were compared to MVIC-based estimated submaximal efforts. Significant moderate - good correlations existed for both the RR (r = 0.691) and NR (r = 0.620) methods, regardless of test-side or shoulder motion. Significant moderate - good correlations were found between both methods for both ER [RR (r = 0.717) and NR (r = 0.614)] and IR [RR (r = 0.669) and NR (r = 0.628)]. Conclusion Both methods had moderate - good accuracy levels and were not influenced by the test side or direction of force. Either method (RR or NR) can be equally useful for shoulder isometric exercise prescription when an ipsilateral reference cannot be determined. Level of Evidence 3

Published: January 2025

Background Due to its significant unilateral predominance, tennis can provoke functional and morphological asymmetries that develop over time and may result in undesired morphological alterations. Hypothesis/Purpose The goals of this study were a) to assess glenohumeral range of motion and muscular stiffness in young tennis players with and without a history of shoulder pain and b) to examine interlimb asymmetries in these variables in both groups. It was hypothesized that players with a history of shoulder pain would show a reduced glenohumeral internal rotation (IR) and total arc of motion (TAM) and increased stiffness in internal rotator muscles compared to those without shoulder pain. Study Design Cross-sectional observational study. Methods Twenty-five participants participated in the study (11 with a history of shoulder pain and 14 without pain). Participants performed stiffness measurements on muscles involved in the main tennis stroke motions alongside range of motion examinations on the dominant (D) and non-dominant (ND) extremities including IR, external shoulder rotation (ER), and TAM. A two-way mixed-design ANOVA analyzed group and limb effects, with effect sizes classified as small, medium, or large. Significant effects were further examined using Bonferroni post hoc tests. Results There were significant differences between the shoulder pain and no shoulder pain group in the D IR (-3.1º, 6.43%, p = 0.048; effect size [ES] = 0.58) and D TAM (-6.1º, 3.01%, p = 0.024; ES = 0.66). Moreover, significant differences were found between the D and ND extremities in IR in both groups (-9.2º, 14.94%, p < 0.001; ES = -1.72) and TAM in the shoulder pain group (-5.6º, 2,77%, p = 0.038; ES = 0.61). Stiffness measurements showed no significant differences between groups or extremities. Conclusions Significantly lower values of D IR and TAM and higher IR asymmetries in the shoulder pain group suggest that a deficit in these parameters could be associated with shoulder pain history in junior competitors.

Published: January 2025

Background The sport of rifle places unique physical demands on its athletes relative to other collegiate sports, including maintaining lumbar-straining positions for extended time. Anecdotal reports of low back pain (LBP) are common among collegiate rifle athletes, but the prevalence of LBP in this population has not yet been established in the literature. Purpose The purpose of this study was to survey collegiate rifle athletes to quantify the prevalence and impact of low back pain in this population and identify possible contributing factors including the COVID-19 pandemic. It was hypothesized that over 50% of athletes would report an episode of LBP due to participation in collegiate rifle events. Study Design Cross-Sectional Study Methods Athletes at least 18 years of age who were members of a collegiate rifle program during the 2019-2020 season were surveyed via an online questionnaire. The questionnaire included four sections: (a) demographics, (b) presence of LBP, (c) the impact of pain episodes on daily activities, and (d) shooting stance and training characteristics. Results Responses from 114 athletes were collected. A total of 101 (89%) respondents indicated having experienced at least one episode of LBP. Of those, 24% also missed at least one day of training or competition during the 2019-2020 season because of LBP. During the COVID-19 pandemic, 60% were unable to receive the same level of medical care while 69% experienced equal or greater pain levels. An association between sex and LBP was statistically significant (p<0.001). Conclusion There is a high prevalence of LBP in collegiate rifle athletes. It is necessary for Athletic Training staff and other medical professionals to be aware of this for prevention and treatment, as it has significant impacts including missed playing time. More research on predisposing factors such as sex and training duration or positional characteristics would benefit management of this injury. Level of Evidence 3

An Advanced Adaptive Mesh for Beam-Column Finite Elements on Transient Dynamic Analysis
Authors: Martinez Edgar David Mora , Khaji Naser 
Published: January 2025

This research examines the influence of truncation error reduction on the nonlinear dynamic analysis of complex framed structures. A modified -adaptive method, incorporating inertial and damping forces in addition to the common restitutive forces, is introduced to refine the mesh and enhance accuracy. To address convergence challenges arising from increased complexity, Ritz modal shapes are utilized to reconstruct the mass matrix, excluding detrimental modes. The proposed formulation is validated through rigorous computational models and experimental data. Six building case studies, varying in complexity, were analyzed using the modified -adaptive method. The results revealed substantial variations in frequency and displacement responses, ranging from 6% to 50% and 0.8% to 63%, respectively. These disparities underscore the significant influence of nonlinear behavior on structures with high-order shape functions. The proposed formulation is theoretically more accurate. Therefore, the findings emphasize the necessity of employing mesh refinement techniques to obtain accurate nonlinear dynamic analysis results, particularly for complex structures with pronounced nonlinear characteristics. This study contains the background of a software called MainModelingStr. Doi: 10.28991/CEJ-2024-010-12-01 Full Text: PDF

This study aims to analyze and compare perceptions of the Belt and Road Initiative (BRI) between border and non-border regions in Thailand, addressing a gap in understanding how geographic proximity influences BRI project views. Using a sample of 3,200 respondents, this study employed confirmatory factor analysis and measurement invariance techniques to examine perceptions across eight key constructs related to BRI impacts. The findings reveal significant structural differences in BRI perceptions between border and non-border regions. Non-border regions generally showed more consistently positive perceptions across all constructs, while border regions demonstrated more varied and nuanced views. Notable differences were observed in perceptions of economic benefits, logistics improvements, and social impacts. This study contributes to the field by providing a comprehensive comparative analysis of BRI perceptions across different geographical contexts within a single country, employing advanced statistical methods to ensure valid comparisons. The results suggest the need for tailored approaches to BRI implementation and communication in different regions, implementing inclusive policy-making processes, and establishing robust monitoring and evaluation systems to address the varied perceptions and potential impacts of BRI projects in Thailand.

Published: January 2025

Global food production and water distribution are at risk due to increasing temperatures and changing precipitation trends. The main objective of the study was to analyze the climate trend and future projections in seven stations in southern Iraq. The period (1981–2020) was designated as a base period. The periods (2021-2040) and (2041-2060) were defined as the future two periods. The Mann-Kendall trend test was employed to assess trends utilizing XLSTAT. The study employed the most recent version of the LARS-WG 8 model to forecast climate change by using three GCMs (ACCES-ESM1-5, HadGEM3-GC31-LL, and MRI-ESM2-0). These simulations are based on two scenarios (SSP-245 and SSP-585). The statistical indicators provided support for the outcomes of model calibration and validation, demonstrating its competence and reliability. The results of this analysis indicate that there is a non-significant increase in precipitation and a considerable increase in both maximum and minimum temperatures during the period (1981-2060). The downscaled result reveals an increase in monsoon precipitation in the range of 2.233-2.831 mm under SSP-245 and SSP-585, respectively, compared with the base periods 1981-2020 during the Near Future and 1.988-2.543 mm during the mid-future. Also, annual maximum/minimum temperature increases in the range of (1.156-1.549 °C) and (1.486-1.770 °C) during the Near Future. (2.095-2.892 °C) and (1.486-1.770 °C) during the mid-future, respectively, for SSP-245 and SSP-585. These outcomes can enhance understanding to develop strategies for mitigating and adapting to these impacts. Doi: 10.28991/CEJ-2024-010-12-014 Full Text: PDF

Road performance can also decline due to natural disasters such as earthquakes, often in Indonesia. Given the high risk of natural disasters in Indonesia, it is important to consider their impact. Therefore, it is necessary to prepare for road rehabilitation and reconstruction quickly and accurately. This research aims to identify potential factors causing road damage by developing an approach to obtain predictions of road damage levels due to natural disasters by utilizing the availability of historical data, developing a decision support system to rehabilitate and reconstruct roads after disasters, and developing a road damage model due to earthquakes using data mining. The data was used to assess the condition of the national road pavement in Central Sulawesi and identified the disaster events as earthquakes that originated from the USGS. Data processing uses a data mining (DM) approach, which includes three models. The results found that the SVM modeling with the DM approach had a high accuracy rate of 0.91 ± 0.01, RMSE 0.70 ± 0.02, and MAD 0.42 ± 0.01. SVM achieves the highest accuracy after 20 runs. The best hyperparameters to accomplish a fit SVM model are ϵ = 0.07 ± 0.01 and γ = 0.05 ± 0.00. Meanwhile, for ANN, the hyperparameters are H = 3 ± 1. The earthquake’s magnitude (27%) and depth (24%) contribute to road damage. Doi: 10.28991/CEJ-2024-010-12-015 Full Text: PDF

Authors: Iftikhar Amir , Khan Zawar H. , Aaron Gulliver T. , Khattak Khurram S. , Ahmed Irfan 
Published: January 2025

Accurate traffic characterization is essential for congestion mitigation. In this paper, a traffic model is proposed that incorporates distance headway in the well-known Lighthill, Whitham, and Richards (LWR) model. Velocity is influenced by the headway distance between vehicles. When this distance is small, the velocity is low, and when it is large, the velocity is high. The proposed and LWR models are implemented in MATLAB, and the performance is evaluated for different values of distance headway. The results show that traffic with the proposed model evolves with smaller changes that are more accurate and realistic than with the LWR model. Doi: 10.28991/CEJ-2024-010-12-016 Full Text: PDF
