ABSTRACT

PURPOSE: To analyze a series of cases with and without medial meniscal posterior root tears (MMPRTs) to determine whether varus alignment and increased sagittal medial tibial slope (MTS) are risk factors for MMPRTs.

METHODS: The study evaluated 2 groups of patients: The tear group included patients with arthroscopically confirmed MMPRTs, and the no-tear group consisted of control patients matched to the tear group who underwent similar imaging but did not have meniscal root tears. Age, sex, side of injury, and body mass index were recorded for all cases. Preoperative joint space height and Kellgren-Lawrence grade were measured on radiographs. Group matching was performed based on demographic factors (age, sex, and body mass index), joint space height, and Kellgren-Lawrence grade. Mechanical axis measurements were determined from full-limb-length radiographs. MTS was analyzed on preoperative magnetic resonance imaging. Two observers performed the measurements on 2 separate occasions, and intraobserver reliability and interobserver reliability were analyzed using the intraclass correlation coefficient (ICC). Multivariate regression analysis was performed to identify potential risk factors associated with MMPRTs.

RESULTS: Of the 142 matched patients included, 76 had root tears (tear group) and 66 did not (no-tear group). Both mechanical axis (183.2° ± 3.2° vs 181.2° ± 2.3°) and MTS (4° ± 1.9° vs 2.4° ± 2.5°) measurements were significantly greater in the tear group (P < .01 for each). However, despite the statistical significance, the small degrees of difference between the groups raises questions about the clinical significance. The intraobserver ICCs were 0.98 and 0.99 for mechanical axis and 0.87 and 0.98 for MTS. The interobserver ICCs showed excellent reliability for mechanical axis (0.95) and good reliability for MTS (0.77). The lower intraobserver and interobserver reliabilities for MTS measurements also suggest a higher likelihood of error. The multivariate logistic regression model indicated that the risk of sustaining an MMPRT increased with varus alignment (odds ratio, 1.268; 95% confidence interval, 1.104-1.478; P = .001) and increased MTS (odds ratio, 1.364; 95% confidence interval, 1.137-1.677; P = .002).

CONCLUSIONS: In this study, MMPRTs were associated with varus alignment and steeper MTS. However, the clinical significance of these associations may be limited owing to the small differences between the groups.

LEVEL OF EVIDENCE: Level III, retrospective case-control study.

ABSTRACT

PURPOSE: To determine the safest screw length that will avoid penetrating the femoral physis for surgical fixation of juvenile osteochondritis dissecans lesions and to compare the safe screw lengths for different regions in the condyles.

METHODS: After institutional review board approval, we retrospectively reviewed T1-weighted magnetic resonance images of pediatric patients. Longitudinal axis reference lines were made on the femur. Lines were then placed at 45° anterior and posterior to this axis to simulate screw start points. From these points, we measured the shortest distance from the articular surface to the physis, noting the shortest distances. These measurements simulated screw lengths in the anterior, posterior, and central regions on both the medial and lateral condyle. Statistical analysis was performed to determine the 95% confidence interval for all measurements. Analysis of variance was performed to compare different regions.

RESULTS: A total of 97 knee magnetic resonance images from patients aged 6 to 17 years were reviewed. The safe screw lengths among all samples were 14.1 mm, 20.9 mm, 18.2 mm, 14.4 mm, 17.5 mm, and 14.1 mm for the anteromedial, central medial, posteromedial, anterolateral, central lateral, and posterolateral regions, respectively. There was a difference in simulated screw lengths among all 6 groups (P < .001). There was a moderate correlation between increasing age of the patient and increasing screw length (r = .397, P < .001).

CONCLUSIONS: While a screw length of 14 mm appears to be safe in all ages and regions of the distal femur, safe screw length varies based on age and location of the lesion. The posteromedial region has a safe length of 18 mm.

CLINICAL RELEVANCE: Surgeons must respect the physis when repairing knee osteochondritis dissecans lesions in pediatric patients. Fluoroscopic confirmation should be used to confirm safe screw lengths, and surgeons should use caution when using screws longer than 14 mm (or 18 mm posteromedially), particularly in younger patients.

ABSTRACT

PURPOSE: To compare the clinical outcomes of rotator cuff repair using a double-row modified Mason-Allen stitch (DR-MA) with those repaired with a double-row suture bridge (DR-SB).

METHODS: A retrospective case-control matching study was conducted to compare the results of patients who received complete supraspinatus tendon repair using a DR-MA configuration and a DR-SB pattern between 2009 and 2020. Exact matching was performed for patients with intact rotator cuff repair at postoperative magnetic resonance imaging. The matching criteria included sex, workers’ compensation, smoking status, hyperlipidemia, size and retraction of tear, and acromioplasty. Clinical outcomes, including visual analog scale (VAS), American Shoulder and Elbow Surgeon (ASES) score, and active shoulder forward flexion (FF), were documented at the 2-year follow-up. The percentage of patients who achieved minimum clinically important difference (MCID) was reported.

RESULTS: A total of 64 patients, including 28 men and 36 women, were matched, and the 2-year follow-up rate was 100%. All patients received postoperative magnetic resonance imaging at 19 ± 11 months. Significant improvement in all clinical outcomes was observed, regardless of the repair pattern (P < .001). The 2-year VAS was better in the DR-MA group compared to the DR-SB group (1.5 ± 2.0 and 2.9 ± 2.6, respectively; P = .009). At the 2-year follow-up, 91%, 90%, and 63% of patients in the DR-MA group achieved MCID in VAS, ASES, and FF, respectively. There was no difference in the proportion of patients achieving MCID between the 2 treatment arms. However, a more substantial improvement in VAS (P = .008), ASES (P = .014), and FF (P = .039) between preoperation and the 2-year follow-up was noted in the DR-MA group.

CONCLUSIONS: No clinical differences in pain or function were found between DR-MA and DR-SB despite small and statistically significant differences in favor of DR-MA.

ABSTRACT

PURPOSE: To analyze the etiology, diagnosis, and incidence of head and neck (HN) injuries among ocean surfers.

METHODS: The National Electronic Injury Surveillance System database was queried for surfing HN injuries presenting to United States emergency departments (EDs) between January 2003 and December 2022. Date of presentation, age, sex, race, injured body part, injury diagnosis, and disposition, as well as a brief injury narrative, were included in the data. National estimates (NEs) were calculated using the associated statistical weight of the reporting hospital.

RESULTS: A total of 1,359 surfing-related HN injuries (NE, 90,872) were included in this study. The average age at presentation was 29.2 ± 13.8 years (range, 3 to 81 years). The most commonly specified mechanisms of injury were impact with board (NE, 48,360 [53%]) and impact with ocean floor (NE, 8,690 [10%]). Concussions represented 5% of surfing HN injuries and occurred at a higher rate (8%) in the age group younger than 20 years. There were statistically significant decreases in overall HN injuries (P < .01) (coefficient, -270; 95% confidence interval [CI], -355 to -206), lacerations (P < .01) (coefficient, -208; 95% CI, -258 to -158), and impact-with-board injuries (P < .01) (coefficient, -177; 95% CI, -327 to -117) presenting to United States EDs from 2003 to 2022.

CONCLUSIONS: Although surfing HN injury ED presentations decreased from 2003 to 2022, the rate of surfing-related concussions presenting to EDs remained steady. Concussions therefore remain a significant concern in surfing, especially among surfers under 20 years of age.

CLINICAL RELEVANCE: As the sport of surfing has increased in popularity, it is important to understand the range of surfing injuries seen in EDs. HN injuries, especially concussions, should be thoroughly investigated to better understand the risks of ocean surfing, to advise athletes, and to develop effective injury prevention strategies.

ABSTRACT

PURPOSE: To examine a method to visualize a 3-dimensional (3D) rendered distal femur using 3D curvature analysis and to compare models of patellofemoral instability (PFI) with controls to study the reliability of the entry point to trochlear groove angle (EPTG) metric.

METHODS: The 3D models of patients with recurrent patellar instability, defined by at least 2 reported patellar dislocation events, and age- and sex-matched controls were created from computed tomography scans. Curvature was calculated to highlight the proximal trochlear ridges and the trochlear groove by overlaying them on the 3D models. Anteroposterior views with and without curvature visualization were created and used for qualitative comparison and to measure the EPTG. The EPTG was measured by 2 raters with and without the aid of the curvature maps. Significant differences between patients with PFI and controls were compared with a Mann-Whitney U test. Inter-rater reliability was calculated using interclass correlation coefficients, classified according to literature and compared using a permutation test. Significance was assumed at .05.

RESULTS: Qualitive analysis between 30 PFI patient knees (age: 23.9 ± 8.4 years, female/male: 24/6) and 30 control knees (age: 21.8 ± 5.6 years, female/male: 22/8) showed that in general, patients with PFI have a lateralized medial ridge and trochlear groove, with the trochlear groove being shorter and shallower. Qualitatively, differences between patients with PFI and controls were significant for measurements both with and without the aid of the curvature maps. Inter-rater reliability was significantly (P = .0349) better when using the curvature visualization.

CONCLUSIONS: Curvature-based visualization aids overlain on a 3D model have the power to increase the information gained from 3D imaging and corresponding 3D models, amplifying their potential value in clinical decision-making. Such visualizations facilitate both the identification of qualitative differences between patient and control morphology and improve the reliability of the EPTG trochlear dysplasia metric.

ABSTRACT

PURPOSE: To investigate the changes in minimum joint space width (mJSW) caused by superficial medial collateral ligament (sMCL) transection during open-wedge high tibial osteotomy (OWHTO).

METHODS: This study included consecutive patients with a diagnosis of medial unicompartmental knee osteoarthritis who were scheduled for OWHTO between September 2020 and August 2022. Intraoperative fluoroscopic evaluations of mJSW were performed under neutral, valgus stress, and varus stress positions in knee extension and 20° of flexion before sMCL transection, after transection, and after plate fixation. Changes in mJSW and increases in valgus stress were calculated and compared using analysis of variance. Linear regression analysis was performed to investigate the related factors for increased mJSW after transection.

RESULTS: We included 44 knees in 43 patients in the final statistical analysis. The maximum mJSW occurred during valgus stress after sMCL transection at 20° of flexion and returned to baseline after plate fixation. Under the valgus stress condition, mean mJSW before transection was 5.1 ± 0.9 mm in extension and 5.5 ± 1.1 mm at 20° of flexion. It increased significantly after transection to 7.8 ± 1.4 mm (P < .001) and 9.2 ± 2.1 mm (P < .001), respectively. Regression analysis showed that increased mJSW after transection in extension positively correlated with the knee extension angle (P = .032). Overall, mJSW increased with sMCL transection regardless of the preoperative condition.

CONCLUSIONS: Transection of the sMCL in OWHTO effectively enlarged the mJSW to 9.2 mm, which was 3.8 mm greater than that before transection, facilitating medial meniscal procedures. After plate fixation, the mJSW returned to pre-transection levels.

LEVEL OF EVIDENCE: Level Ⅳ, therapeutic case series.

ABSTRACT

PURPOSE: Computer-assisted technology offers better component alignment and surgical precision than conventional TKA. However, whether robotic-assisted total knee arthroplasty (RA-TKA) shows clear benefits over navigation-assisted total knee arthroplasty (NA-TKA) is still contentious. Therefore, we aimed to perform a meta-analysis exploring the accuracy and safety of RA-TKA compared to NA-TKA in patients with knee osteoarthritis.

METHODS: We systematically searched PubMed, Scopus, Web of Science, and Cochrane Library for studies comparing RA-TKA with NA-TKA. We assessed radiological alignment outliers, polyethylene (PE) insert thickness, surgical time, and safety outcomes. Statistical analyses were performed using RevMan Web. Odds ratios (ORs) and mean differences (MDs) with 95 % confidence intervals (CIs) were pooled for dichotomous and continuous endpoints, respectively. A random-effects model was used due to anticipated heterogeneity and measured with the I² test.

RESULTS: We included 19,209 patients from sixteen studies, of whom 3764 (19.6 %) were assigned to the RA-TKA. We found no statistically significant difference between RA-TKA and NA-TKA in terms of hip-knee-ankle angle outliers (OR 0.91; 95 % CI 0.56 to 1.48; p = 0.71; I² = 25 %), femoral coronal angle outliers (OR 0.46; 95 % CI 0.16 to 1.38; p = 0.17; I² = 60 %), tibial coronal angle outliers (OR 0.51; 95 % CI 0.13 to 2.08; p = 0.09; I² = 58 %), periprosthetic joint infection (OR 0.76; 95 % CI 0.27 to 2.15; p = 0.61; I² = 0 %), and length of stay MD -0.17 days; 95 % CI -1.08 to 0.74; p = 0.72; I² = 98 %). RA-TKA used 1.03 mm thinner PE inserts compared with NA-TKA (MD -1.03 mm; 95 % CI -1.60 to -0.46; p = 0.71; I² = 98 %), whereas surgical time was 9.87 min shorter with NA-TKA (MD 9.87 min; 95 % CI 0.62 to 19.11; p = 0.04; I² = 99 %).

CONCLUSIONS: RA-TKA and NA-TKA had comparable radiological alignment. While RA-TKA allows for thinner polyethylene inserts, it requires longer surgical time than NA-TKA. These findings suggest that both techniques are adequate, with specific differences that may influence surgical decision-making.

ABSTRACT

Background: Malaria is a deadly vector-borne parasitic disease spread by the bite of an infective female Anopheles mosquito. In routine malaria diagnosis, microscopic examination is generally regarded as the gold standard. Our study sought to evaluate the diagnostic precision of two commercially accessible quantitative PCR (qPCR) kits, in contrast to light microscopy and nested multiplex PCR (NM-PCR). Methods: This cross-sectional study in southwest Saudi Arabia included 92 febrile patients meeting the inclusion criteria. Detection of Plasmodium species used light microscopy, NM-PCR, and qPCR kits (RealStar and Viasure). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and receiver operating characteristic (ROC) curves were calculated. Statistical analysis was performed using SPSS v25, with significance set at p ≤ 0.05. Results: Light microscopy detected 92.4% of cases, NM-PCR detected 73.9%, and RealStar and Viasure detected 92.4% and 95.7%, respectively. Viasure showed the highest sensitivity (97.6%) and NPV (50%), while NM-PCR had superior specificity (71.4%). For species identification, Plasmodium falciparum detection was highest with RealStar (85%). Mixed infections were better identified by Viasure (34.6%). RealStar excelled in Plasmodium vivax detection (area under the curve [AUC] = 90%). qPCR detected low parasitemia levels missed by microscopy. Conclusions: The qPCR kits, particularly Viasure, demonstrated superior sensitivity for detecting Plasmodium species and identifying mixed infections compared to light microscopy and NM-PCR. While light microscopy showed higher specificity and PPV, qPCR effectively detected low parasitemia levels missed by microscopy, highlighting its value in improving malaria diagnostics.

ABSTRACT

Cystic echinococcosis (CE) is a neglected parasitic infection with a particular impact in humans and livestock. The current investigation was undertaken to design and evaluate a DNA vaccine encoding Echinococcus granulosus Eg95-1 to EG95-6, P29, and GST against hydatid cyst infection in BALB/c mice. Initially, B-cell, cytotoxic T-lymphocyte, and helper T-lymphocyte epitopes were forecasted using B-cell epitope prediction server (BCPREDS) and Immune Epitope Database (IEDB) server, respectively, and a vaccine construct incorporating multiple epitopes was rationally designed and comprehensively analyzed through in silico modeling and simulation studies. Next, Escherichia coli TOP10 was transformed by the recombinant pcDNA 3.1 plasmid and mass production, followed by plasmid extraction, was done. The BALB/c mouse immunization was done with 50 and 100 μg concentrations of plasmid combined with IL-12 adjuvant or alone. Mouse sera and splenic lymphocytes were used for the measurement of specific humoral and cellular responses. The candidate vaccine model weighed 37.49 kDa with 338 residues antigenic, while nonallergenic, soluble, stable, highly thermotolerant, and hydrophilic in nature. Expression in HEK-293 cells was successfully achieved, as evidenced by the detection of a 37 kDa protein band in the western blot analysis. Vaccine doses, especially the 100 μg concentration, alone or in combination with an adjuvant, induced a T-helper 1 (Th1)-type immune response. This was evidenced by higher levels of IgG2a antibody and interferon gamma (IFN-γ) along with lower levels of interleukin 4 (IL-4). Although the groups that received the 50-μg dose of vaccine alone or with adjuvant showed a lower immune response, overall, the vaccinated groups showed statistically significant differences compared to the control groups (phosphate-buffered saline (PBS) and pcDNA). The promising results of this vaccine candidate can be further examined using challenges with various parasite genotypes.

ABSTRACT

BACKGROUND AND AIMS: The study’s goal was to assess the global prevalence of HIV/AIDS infection in transgender people and to provide light on regional variances.

METHODS: A systematic search was conducted across multiple databases, including PubMed (Medline), Scopus, Web of Science, Embase, Ovid, and PsycINFO, from inception until September 2023. Studies were selected based on predefined inclusion and exclusion criteria, and quality was assessed using the Newcastle-Ottawa Scale (NOS). Heterogeneity was evaluated using Cochran’s Q and I-squared statistics. A meta-analysis was performed using the random-effects model in Stata 17.0 (StataCorp, Texas, USA). A total of 3125 articles were identified, of which 37 studies met the inclusion criteria and were included in the systematic review and meta-analysis.

RESULTS: The global prevalence of HIV/AIDS among transgender populations was 24% (CI: 12%-39%). Regional analysis revealed higher rates of HIV/AIDS among male-to-female (MTF) transgender individuals in Asia (30%, CI: 5%-54%) and Africa (35%, CI: 13%-57%) compared to other regions. In contrast, female-to-male (FTM) transgender individuals in Asia had a higher prevalence (23%, CI: 9%-31%) than those in the Americas (11%, CI: 3%-23%).

CONCLUSION: Given the high prevalence of HIV/AIDS in the TG community worldwide and the significant variance within communities, it is critical to execute a comprehensive set of interventions to successfully prevent HIV/AIDS in transgender people.
