Anterior cruciate ligament-Return to sport after injury scale brief version after ACL reconstruction: Persian translation, cross-cultural adaptation and validation.

Purpose: The purpose of this study is to analyze the short anterior cruciate ligament return to sport after injury (ACL-RSI) (Persian) version's cultural adaption and validity. Methods: To assess test-retest reliability, 102 participants were filled out the short ACL-RSI(Per) scale 6 months or more after ACLR surgery. Internal consistency (Cronbach's alpha), test-retest reliability (intraclass correlation coefficients), construct validity (Pearson's r) and sensitivity (floor/ceiling effect) were determined. In addition, patient completed other relevant measures such as Lysholm scores, the hospital for special surgery ACL satisfaction survey (HSS ACL-SS), the visual analogue scale (VAS) of pain and patient's satisfaction, the Tegner activity score (TAS), the single assessment numeric evaluation (SANE) and the Cincinnati Knee Rating System (CKRS). Results: The short ACL-RSI(Per) scale showed high internal consistency (Cronbach's alpha = 0.91) and test-retest reliability (ICC = 0.923). Significant correlations between short ACL-RSI(Per) and other scales supported validity. There was a statistically significant connection between the short ACL-RSI(Per) and the following outcomes: HSS ACL-SS (r = 0.698, p < 0.001), VAS pain (r = 0.356, p < 0.001), CKRS (r = 0.644, p < 0.001), TAS (r = 0414, p < 0.001), Lysholm score (r = 0.467, p < 0.001) and SANE score (r = 0.536; p < 0.001). In addition to a satisfactory ceiling impact (15%), a sizeable floor effect (16.7%) was also seen. Conclusion: The short ACL-RSI(Per) scale is a reliable and valid tool for assessing psychological readiness for return to sport after ACL reconstruction in Persian. Level of Evidence: III.

Validity and reproducibility of the ARL-RSI score to assess psychological readiness before returning to sport after lateral ankle sprain.

Purpose: Although multiple scales exist to evaluate psychological readiness before returning to sport post-lateral ankle sprain (LAS), no score has been validated specifically for LAS or chronic ankle instability. The main aim of the study is to evaluate the validity and reproducibility of the ankle ligament reconstruction-return to sport injury (ALR-RSI) scale in assessing psychological readiness after LAS and its ability to identify patients who can return to their preinjury level. Methods: A total of 64 patients (35 females and 29 males; 33.8 ± 13.2 years) who recently experienced an acute LAS were included in this study. All patients participated in a predictive validation component of the study and were assessed at 2 and 4 months following an LAS. The ALR-RSI was completed twice by 20 patients at a 7-day interval to evaluate the reliability of the score in patients suffering from LAS. Results: The ALR-RSI was significantly (p < 0.001) and positively correlated with the other scores. The correlation was strong with the Foot and Ankle Ability Measure Sports: r = 0.77; 95% confidence interval [CI]: 0.78-0.83) and moderate with the American Orthopaedic Foot and Ankle Society (r = 0.69; 95% CI: 0.60-0.78) and the Foot and Ankle Ability Measure Activities of Daily Living Scores (r = 0.63; 95% CI: 0.51-0.72). Two-month ALR-RSI scores had good ability for predicting nonreturners at 4 months (area under the curve = 0.76; 95% CI: 0.6-0.9; p = 0.005). A Youden index of 0.51 was observed at an ALR-RSI score of 46%, corresponding to a sensitivity of 67% and specificity of 83%. Test-retest reliability of the ALR-RSI was excellent, with an ICC of 0.98 (95% CI: 0.96-0.99), a standard error of measurement of 3.02% and a minimum detectable change of 8.37%. Conclusions: The results of the current study validated the ALR-RSI as an important questionnaire to assess psychological readiness to return to sport after LAS. Level of Evidence: Level II prospective cohort study.

Ankle ligament reconstruction-return to sport after injury scale and return to sports after ankle ligament reconstruction or repair-A systematic review.

Purpose: To systematically review existing literature regarding the ankle ligament reconstruction-return to sport after injury (ALR-RSI) scale and to assess its correlation with Return to sport and functional outcomes as well as feasibility, reliability and consistency. Methods: A systematic review of the literature based on the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) was conducted using PubMed, Embase and Cochrane Library. Studies that evaluated psychological readiness to return to sport after ankle ligament reconstruction or repair for the treatment of chronic lateral ankle instability using the ALR-RSI scale were included. The results from each study were pooled, and weighted means and overall rates were calculated. Results: In total, 157 patients (53.2% male, mean age: 34.2 years) from three articles were included. Overall, 85.0% of patients reported successful return to sport, but only 48.9% of patients returned to the preoperative sporting level. All studies reported a significant difference in psychological scores between patients who returned to sport and those who did not. Pooled mean patient-reported outcome measures, reported as the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot (AOFAS, three studies) Score and Karlsson-Peterson Score (three studies), were 82.7 (range: 29-100) and 81.7 (range: 25-100), respectively. The ALR-RSI scale demonstrated strong correlations with the AOFAS Score and Karlsson-Peterson Score. Conclusion: Patients who returned to sport after ankle ligament reconstruction or repair exhibited higher psychological readiness compared to those who did not. The ALR-RSI scale showed strong correlations with ankle function. Evaluation of psychological readiness using the ALR-RSI scale may provide an additional tool in the assessment of patients who underwent ankle ligament reconstruction or repair. Level of Evidence: Level III, systematic review.

Reliability and Validity of Temporal Parameters during the Side Hop Test in Patients after Anterior Cruciate Ligament Reconstruction.

Background: The side hop test (SHT) measures the number of jumps performed over 30 s. Although this measure has demonstrated its value in clinical practice, the temporal parameters of the SHT allow for a deeper analysis of the execution strategy. The aim of this study is to assess the reliability and construct validity of contact time parameters during the SHT recorded by a video analysis system in anterior cruciate ligament reconstructed (ACLR) patients. Methods: We investigated the reliability (intra-rater, standard error of measurement (SEM), and minimum detectable change (MDC)), discriminant validity (operated (OP) versus non-operated (NOP) side), and convergent validity (relationship with strength and psychological readiness) of SHT contact time parameters, number of valid hops and limb symmetry index (LSI) in 38 ACLR patients. Contact time parameters are presented as mean, standard deviation (SD), and coefficient of variation (CV) of contact time. Results: Intra-tester reliability was good to excellent for all contact time parameters. For discriminant validity, the mean and SD contact times of the OP leg were significantly longer than those of the NOP leg, although the difference was smaller than the SEM and MDC values. The number of valid jumps and CV contact time parameters were not significantly different. Isokinetic quadriceps strength (60°/s) was strongly correlated with mean contact time for both legs. However, psychological readiness was not correlated with any of the contact time parameters. Conclusions: Temporal parameters of the SHT measured on video analysis are valid and reliable parameters to assess the performance strategy of the SHT. The results should be interpreted with caution regarding the SEM and MDC values. Further studies are needed to measure criterion validity, inter-rater reliability, and responsiveness.

Association of Patient-Surgeon and Patient-Physical Therapist Relationships With Return to Sports After ACL Reconstruction: The Untested Dimension in Outcome Assessments.

Background: The Quality of Patient-Surgeon Relationship (QPASREL) is an 11-item questionnaire developed and validated to assess the relationship between practitioners and patients on recovery and return to work after surgery. Purpose: To evaluate the association of patient-surgeon relationship (PSR) and patient-physical therapist relationship (PPR), as measured by QPASREL, with a patient's return to sports (RTS) after anterior cruciate ligament reconstruction (ACLR). Study Design: Case-control study; Level of evidence, 3. Methods: This study targeted patients who underwent primary ACLR at a specialized sports surgery referral center between January and May 2021. Patients who had revision surgery, multiligamentous knee injury, and sedentary status were excluded from the study. Patients were grouped based on ability to RTS at the preinjury level 1 year postoperatively (RTS group and no-RTS group). The primary outcome was rate of RTS at 1 year postoperatively, and the primary dependent variables were the quality of PSR and PPR as measured by QPASREL scores at 6-month intervals. Secondary outcomes were the correlation and discriminative capacity of the QPASREL compared with the Anterior Cruciate Ligament-Return to Sport After Injury (ACL-RSI) scores (collected at 6-month intervals). Results: The study included 243 patients. Patients in the RTS group exhibited a higher mean PPR QPASREL score (36.6 ± 5.1) compared with no-RTS patients (34.8 ± 5.2; P = .01) as well as a higher mean PSR score (35.7 ± 5.1) compared with no-RTS patients (33.8 ± 5.9; P = .01). Multivariate analysis showed that every 5-point increase in the QPASREL scores for PPR and PSR resulted in a 39% (odds ratio [OR] = 1.39; P = 0.014) and 35% (OR = 1.35, P = 0.021) increased odds of RTS, respectively. A weak yet positive correlation was found between QPASREL and ACL-RSI. The predictive capacity of the QPASREL (area under the curve [AUC] = 0.60 for PPR and 0.61 for PSR), although significant, was less powerful compared with that of the ACL-RSI (AUC = 0.73). Conclusion: The quality of the PPR and PSR, as measured by QPASREL scores, demonstrated a significant association with RTS rates at 1 year after ACLR. A weak yet positive correlation was found between QPASREL and ACL-RSI.

The Production, Assessment, and Utility of 3D-Printed Video Laryngoscopes in Eastern India: A Low-Cost Alternative to Conventional Video Laryngoscopes.

Introduction Recognizing the limitations of traditional direct laryngoscopes, particularly in difficult airway situations, video laryngoscopy has emerged as a potentially safer and more effective alternative. This study evaluated the utility of two 3D-printed video laryngoscopes: a standard geometry video laryngoscope (SGVL), resembling the traditional Macintosh blade, and a hyper-angulated video laryngoscope (HAVL) with a more curved design. Their performance was compared to a standard Macintosh direct laryngoscope across various intubation parameters. By leveraging the cost-effectiveness of 3D printing with polylactic acid, the study aimed to assess the potential of this technology to improve airway management across diverse clinical settings and varying levels of physician expertise. Methods This prospective randomized crossover study compared the effectiveness of 3D-printed video laryngoscopes (VL) and a standard direct laryngoscope in intubation. After obtaining IRB approval, physicians from various specialties across multiple centers participated. Participants received training on SGVL, HAVL, and DL intubation using an instructional video and hands-on practice. The training was standardized for all participants. The primary outcome measures were time to successful intubation, number of attempts, and time to visualize vocal cords. Participants were randomized to use all three laryngoscopes on a manikin, with a maximum of two attempts per scope. A 30-minute break separated each laryngoscope evaluation. Successful intubation was defined as the single insertion of each laryngoscope and bougie, followed by endotracheal tube placement and confirmation of lung inflation. Results Ninety-eight doctors, mostly from the EM team (73.5%) and ICU team (23.4%). Teams consist of consultants, residents, and medical officers of the concerned departments. Forty-eight of the participants (49%) were novice operators (<25 intubations). Successful first-attempt intubation in those with <1 year of experience with intubation (n=33) was highest for SGVL (97%) compared to DL (82%) and HAVL (67%). Participants who learned intubation through self-directed learning exhibited a higher acceptance of VL and achieved 100% success on their first attempt. Among those who followed modules or workshops, 97% had successful first-attempt intubation with VL. The average time taken to visualize the vocal cords was lower in SGVL compared to DL (5.6 vs. 7.5 seconds) (p<0.001). The HAVL also had a lower average time compared to the DL (7.1 vs. 7.5 secs) (p<0.001). However, the time taken to intubate using DL (24.2 ±8.7 sec) was similar to SGVL (28.1 ±13 sec). Lastly, the intubation time using HAVL was the longest (49.6 ±35.5 sec). The time to intubate with DL and SGVL had Spearman's rho of 0.64 (p<0.001), and DL and HAVL had 0.59 (p<0.001). Conclusions The ease of use and its cost-effective nature make 3D-printed VLs beneficial in situations where traditional VLs may not be available, especially in simulation and training.

Utilizing multicompartmental restriction spectrum magnetic resonance imaging for liver fibrosis characterization in a mouse model.

BACKGROUND: Currently, an advanced imaging method may be necessary for magnetic resonance imaging (MRI) to diagnosis and quantify liver fibrosis (LF). PURPOSE: To evaluate the feasibility of the multicompartmental restriction spectrum imaging (RSI) model to characterize LF in a mouse model. METHODS: Thirty mice with carbon tetrachloride (CCl4)-induced LF and eight control mice were investigated using multi-b-value (ranging from 0 to 2000 s/mm2) diffusion-weighted imaging (DWI) on a 3T scanner. DWI data were processed using RSI model (2-5 compartments) with the Bayesian Information Criterion (BIC) determining the optimal model. Conventional ADC value and signal fraction of each compartment in the optimal RSI model were compared across groups. Receiver operating characteristics (ROC) curve analysis was performed to determine the diagnosis performances of different parameters, while Spearman correlation analysis was employed to investigate the correlation between different tissue compartments and the stage of LF. RESULTS: According to BIC results, a 4-compartment RSI model (RSI4) with optimal ADCs of 0.471 × 10-3, 1.653 × 10-3, 9.487 × 10-3, and > 30 × 10-3, was the optimal model to characterize LF. Significant differences in signal contribution fraction of the C1 and C3 compartments were observed between LF and control groups (P = 0.018 and 0.003, respectively). ROC analysis showed that RSI4-C3 was the most effective single diffusion parameter for characterizing LF (AUC = 0.876, P = 0.003). Furthermore, the combination of ADC values and RSI4-C3 value increased the diagnosis performance significantly (AUC = 0.894, P = 0.002). CONCLUSION: The 4-compartment RSI model has the potential to distinguish LF from the control group based on diffusion parameters. RSI4-C3 showed the highest diagnostic performance among all the parameters. The combination of ADC and RSI4-C3 values further improved the discrimination performance.

Comparison of Magnesium Pre-treatment With Two Different Doses of Rocuronium in Rapid Sequence Intubation: A Randomized Controlled Trial.

Introduction Magnesium is recognized for its ability to reduce the onset time of rocuronium while simultaneously extending its duration of action. This study aims to assess the efficacy of magnesium pre-treatment in decreasing the onset time with two different doses of rocuronium in patients undergoing rapid sequence intubation. Materials and methods This randomized prospective double-blind clinical study involved 50 patients classified as American Society Of Anesthesiologists (ASA) I/II, with no preoperative indications of difficult intubation, undergoing elective surgery under general anesthesia. The patients were divided into two groups: group A received 60 mg/kg of magnesium 15 minutes before intubation with 1.2 mg/kg of rocuronium, and group B received 60 mg/kg of magnesium before 0.6 mg/kg of rocuronium. Intubating conditions were assessed and graded at loss of last twitch after administration in both groups, considering ease of intubation, vocal cord position, and response to the insertion of the tracheal tube. Simultaneously, hemodynamic variations were recorded just before intubation, at one minute and five minutes post-intubation. Results Intubating conditions with 0.6 mg/kg of rocuronium were comparable or equally good compared to 1.2 mg/kg of rocuronium with magnesium pre-treatment. Conclusions Magnesium pre-treatment enhances the neuromuscular blocking effect of rocuronium, reducing its onset time without clinically significant prolongation of the duration of the block.

Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) subcategories are affected by subjective running ability and medial single-leg hop distance in postreconstruction patients at 6 months.

Purpose: This study aimed to investigate the intricate relationship between physical function factors and each subcategory score of the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale among patients following ACL reconstruction. Methods: Participants comprised 59 patients who had undergone primary ACL reconstruction using hamstring tendon. The ACL-RSI was completed 6 months after reconstruction and five physical functions were measured in patients on the same day. Simple linear regression was performed multiple times to investigate the relationship between ACL-RSI subcategory scores as a dependent variable and each independent variable (knee strength, leg anterior reach distance, single-leg hop [SLH] distances, side bridge endurance, and subjective running ability). Multiple regression analysis was performed using a stepwise method, with factors showing a risk rate <0.05 in simple linear regression analyses as independent variables and the ACL-RSI in each subcategory score as the dependent variable. Results: Multiple regression analysis showed that subjective running ability affected all subcategories (p ≤ 0.001), and that the limb symmetry index of medial SLH distance affected both the Emotions (p = 0.047) and Confidence (p = 0.009) subcategories. Higher subjective running ability and greater limb symmetry in the medial SLH were thus positively associated with each dimension of psychological readiness. Conclusions: This study highlights the differential impact of physical function factors on specific subcategories of the ACL-RSI scale, providing clinicians with insights for designing targeted rehabilitation strategies. This original paper suggests the importance of analysing factors related to subcategory scores in addition to total ACL-RSI score, and could contribute to the understanding of determinants for a successful return to sport following ACL reconstruction. Level of Evidence: Level IV.

The Ankle Ligament Reconstruction-Return to Sport after Injury (ALR-RSI) is a valid and reliable measure to assess psychological readiness before returning to sport following peroneal tendon pathology surgery.

PURPOSE: The objective of this study was to validate a scale that could help surgeons evaluate patients' psychological readiness to return to sport (RTS) after peroneal tendon pathology surgery. METHODS: The Ankle Ligament Reconstruction-Return to Sport after Injury (ALR-RSI) scale, which had previously been validated in ankle ligament reconstruction patients, was adapted to evaluate the psychological preparedness for RTS in athletic patients who underwent peroneal tendinopathy surgery. The Foot and Ankle Outcome Score (FAOS) and Foot Ankle Ability Measurement (FAAM) scores were employed as patient-related outcome measurement (PROM) instruments. RESULTS: This study included 57 patients. There was a strong correlation between ALR-RSI and both FAOS and FAAM (r = -0.68 and 0.74, respectively). ALR-RSI was considerably higher in patients who returned to sports than in those who did not. The mean score was 72.9 ± 19.0 in patients who returned to the same preinjury level, 48.5 ± 24.0 in those who returned to a lower level and 53.6 ± 31.1 in patients who changed their athletic activity (p < 0.0001). Furthermore, ALR-RSI showed at least a similar discrimination ability when compared to FAOS and FAAM. The test-retest intraclass correlation coefficient was 0.95. The Cronbach's α statistic used to measure the internal consistency was high (0.95). A Youden index of 0.65 was observed for a cut-off score of 68 points. CONCLUSION: ALR-RSI is a valid instrument for assessing psychological readiness to RTS in an athletic population following peroneal tendon surgery. When compared to the most commonly used PROMs, it was strongly correlated and demonstrated at least similar discrimination capacity. This could assist surgeons in identifying athletes who will have poor postoperative results and advising them on their capability to RTS. LEVEL OF EVIDENCE: Level III.

Utility of spectral CT with orthopedic metal artifact reduction algorithms for 125I seeds implantation in mediastinal and hepatic tumors.

Background: Virtual monochromatic image (VMI) combined with orthopedic metal artifact reduction algorithms (VMI + O-MAR) can effectively reduce artifacts caused by metal implants of different types. Nevertheless, so far, no study has systematically evaluated the efficacy of VMI + O-MAR in reducing various types of metal artifacts induced by 125I seeds. The aim of this study was to assess the effectiveness of combining spectral computed tomography (CT) images with O-MAR in reducing metal artifacts and improving the image quality affected by artifacts in patients after 125I radioactive seeds implantation (RSI). Methods: A total of 45 patients who underwent dual-layer detector spectral CT (DLCT; IQon, Philips Healthcare) scanning of mediastinal and hepatic tumors after 125I RSI were retrospectively included. Spectral data were reconstructed into conventional image (CI), VMI, CI combined with O-MAR (CI + O-MAR), and VMI + O-MAR to evaluate the de-artifact effect and image quality improvement. Objective indicators included signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and artifact index (AI) of lesions affected by artifacts. Subjective indicators included assessment of overcorrected artifacts and new artifacts, different morphology of artifacts, and overall image quality. Results: In artifact-affected lesion areas, SNR and CNR in the CI/VMI + O-MAR groups were better than those in CI groups (all P values <0.05). The AI showed a downward trend as VMI keV increased (all P values <0.001). The AI values of the CI/VMI (50-150 keV) group were all higher than the groups of CI/VMI + O-MAR (50-150 keV) (P<0.001). Overcorrection artifacts and new artifacts were concentrated in the VMI50/70 keV groups. In the evaluation of artifact morphology, as the VMI keV increased, the number of near-field banding artifacts in hyperdense artifacts gradually decreased, whereas the number of minimal or no artifacts increased, and the total number of hyperdense artifacts were decreased. The diagnostic and image quality scores of hyperdense artifacts were higher than those of hypodense artifacts as VMI keV increased. Conclusions: High VMI level combined with O-MAR substantially improve objective and subjective image quality, lesion display ability, and diagnostic confidence of CT follow-up after 125I RSI, especially at the VMI + O-MAR 150 keV level.

A Study of the Diagnostic Value of the Sign and Symptom Questionnaires for Laryngopharyngeal Reflux Disease.

OBJECTIVE: To investigate the diagnostic value of symptom questionnaires, sign questionnaires, and the combination of 2 questionnaires for laryngopharyngeal reflux disease (LPRD). STUDY DESIGN: Prospective, single-centered. SETTING: Seventy-seven patients who were hospitalized in the Department of Otolaryngology-Head and Neck Surgery from October 2022 to April 2023 were included. METHODS: Included patients completed the RSS, RSI, RSA, and RFS questionnaires and underwent 24-hour hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH). The RSS, RSI, RSA, RFS, RSS+RSA, RSS+RFS, RSI+RSA, RSI+RFS, and RSI+RFS diagnostic value were compared using Cohen's k test and receiver operating characteristic analysis. RESULTS: Based on the 24 hours HEMII-pH results, 52 patients had LPRD, and 25 patients did not have LPRD. The Kappa values of RSS, RSI, RSA, RFS, RSS+RSA,2 RSS+RFS, RSI+RSA, and RSI+RFS with the 24 hours HEMII-pH monitoring results were 0.565, 0.442, 0.318, 0.431, 0.517, 0.631, 0.451, and 0.461, respectively. The RSS+RFS questionnaire had the highest AUC of 0.836 (95% confidence interval [CI] 0.762-0.909) and the RSA questionnaire had the lowest AUC (AUC = 0.665, 95% CI 0.560-0.790). The sensitivity of RSS was the highest (98%), the specificities of RSS+RFS and RSI+RFS were the highest (96%), and the specificity of RSS was the lowest (52%). RSS+RFS had a sensitivity of 75%, second only to RSS and RFS (76%). CONCLUSION: Among the 8 methods, the RSS combined with the RFS had the highest concordance with 24 hours HEMII-pH monitoring results and AUC values when screening for LPRD.

Short-term fear of movement improves less after anterior cruciate ligament reconstruction with concomitant meniscus repair.

BACKGROUND: Psychological response is important in return-to-sport decisions for athletes recovering from anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to compare psychological response after ACLR with a concomitant meniscus repair compared to isolated ACLR. METHODS: Thirty-five individuals completed the Tampa Scale of Kinesiophobia (TSK) and Anterior Cruciate Ligament Return-to-Sport after Injury (ACL-RSI) scale before ACLR and 2, 4, and 6 months after ACLR. Participants were dichotomized based on presence of concomitant meniscus repair (Yes/No). Separate group X time repeated measures analyses of variance were conducted for both scales. RESULTS: Participants were 65.7% female, 19.1 ± 4.7 years old with BMI of 24.9 ± 4.4 kg/m2. Sixteen individuals had an isolated ACLR with 19 individuals having an ACLR with concomitant meniscus repair. For the TSK, there was a group × time interaction effect(p = 0.028), with improvement in TSK scores for the isolated ACLR group (ACLR:2 months = 24.8 ± 3.7; 4 months = 22.0 ± 5.7; 6 months: 19.9 ± 5.9; Meniscus Repair:2 months = 25.5 ± 4.7; 4 months = 24.1 ± 5.0; 6 months: 23.8 ± 4.7). Six months after ACLR, TSK scores were worse in the meniscus repair group(p = 0.036). For the ACL-RSI, there was no interaction(p = 0.07). CONCLUSION: Concomitant meniscus repair with ACLR results in less post-operative improvement in kinesiophobia through 6 months after ACLR compared to isolated ACLR.

Validation of the Ankle Ligament Reconstruction-Return to Sports after Injury (ALR-RSI) Score as a Tool to Assess Psychological Readiness to Return to Sport in an Active Population After Ankle Fracture Surgery: A Cross-sectional Study.

Ankle injuries account for 15% to 25% of all sports injuries resulting in significant pain and loss of function. The purpose of this cross-sectional study was to validate a scale to help surgeons quantify the psychological readiness to Return To Sport (RTS) in patients undergoing ankle fracture surgery. ALR-RSI was used to assess the psychological readiness for RTS in athletic patients who underwent ankle fracture fixation between January 2020 and January 2021. Participants filled out ALR-RSI and 2 Patient-Related Outcome Measurement (PROM) tools: Olerud-Molander Ankle Score (OMAS) and Self-Reported Foot and Ankle Score (SEFAS). A total of 93 patients were included. There was a strong correlation between ALR-RSI and both OMAS and SEFAS, with Pearson coefficients of r = 0.58 and 0.53, respectively. ALR-RSI was significantly higher in the RTS group than in those who no longer practiced their main preinjury sport. Moreover, the discriminant validity of ALR-RSI (AUC = 0.81) was better than that of the SEFAS and OMAS (AUC = 0.64 and 0.65, respectively, p = .001). The intra-class correlation coefficient ρ of 0.94 showed excellent reproducibility. At an optimal cutoff value of 76.7, ALR-RSI had a sensitivity of 81% and a specificity of 75% with a Youden index of 0.56. In conclusion, ALR-RSI was a valid and reproducible tool to evaluate the psychological readiness for RTS in an active population after an ankle fracture. This score could help surgeons identify athletes who may have unfavorable postoperative outcomes and provide support on the ability to RTS.

THE EFFECT OF TIME AND SEX ON POST-ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION PSYCHOLOGICAL PATIENT REPORTED OUTCOME MEASURE SCORES.

CONTEXT: Low scores on psychological patient reported outcomes measures (PROMs), including the anterior cruciate ligament-return to sport after injury (ACL-RSI) and injury-psychological readiness to return to sport (I-PRRS), after anterior cruciate ligament (ACL) reconstruction (ACLR) have been associated with a maladaptive psychological response to injury and poor prognosis. OBJECTIVE: The purpose of this study was to assess the effect of time post-ACLR and sex on ACL-RSI and I-PRRS scores and generate normative reference curves. It was hypothesized that males would demonstrate higher ACL-RSI and I-PRRS scores than females in the first 1-year post-ACLR. DESIGN: Case series. SETTING: Outpatient sports medicine and orthopedic clinic. PATIENTS: 507 patients post-primary ACLR 12-to-30-years-old with 796 ACL-RSI or I-PRRS scores one or more times between 0- and 1-year post-ACLR (age at ACLR: 17.9 ± 3.0 y). MAIN OUTCOME MEASURES: An honest broker provided anonymous data from our institution's knee injury clinical database. Generalized additive models for location, scale, and shape and generalized least squares analyses were used to assess the effect of time post-ACLR and sex on ACL-RSI and I-PRRS scores. RESULTS: ACL-RSI and I-PRRS scores increased over time post-ACLR, and males had higher scores compared to females up until approximately five months post-ACLR with scores converging thereafter. CONCLUSIONS: Males report higher ACL-RSI and I-PRRS scores compared to females in the initial stages of rehabilitation, but scores converge between sexes at times associated with return to play following ACLR. Normative reference curves can be used to objectively appraise patients' ACL-RSI and I-PRRS scores at any time point post-ACLR. This may lead to timely identification of patients with scores or changes in scores over time post-ACLR associated with a maladaptive psychological response to injury and a poor prognosis and optimized ACLR outcomes.

Hop to It! The Relationship Between Hop Tests and The Anterior Cruciate Ligament - Return to Sport Index After Anterior Cruciate Ligament Reconstruction in NCAA Division 1 Collegiate Athletes.

Background: Outcomes after anterior cruciate ligament reconstruction (ACLR) may not be optimal, with poor physical and psychological function potentially affecting return to sport (RTS) ability. Understanding the relationship between commonly used hop tests and the Anterior Cruciate Ligament - Return to Sport Index (ACL-RSI) may improve rehabilitation strategies and optimize patient outcomes. Hypothesis/Purpose: The purpose of this study was to examine the relationship between ACL-RSI scores and limb symmetry index (LSI) for the single hop for distance (SHD), triple hop for distance (THD), crossover hop for distance (CHD), timed 6-meter hop (T6H), and single leg vertical hop (SLVH) in a cohort of National Collegiate Athletic Association (NCAA) Division 1 collegiate athletes after ACLR. The hypothesis was that SLVH LSI would be more highly correlated with ACL-RSI score than all horizontal hop tests. Study design: Cross-Sectional Study. Methods: Twenty-one National Collegiate Athletic Association (NCAA) Division 1 collegiate athletes (7 males, 14 females) at 6.62 ± 1.69 months after ACLR were included in this retrospective study. Primary outcomes were ACL-RSI score and LSI for SHD, THD, CHD, T6H, and SLVH. The relationship between ACL-RSI scores and performance on hop tests (LSIs) was evaluated using correlation analysis and step-wise linear regression (p ≤ 0.05). Results: There were significant correlations found when comparing ACL-RSI and the LSI for SHD (rs = 0.704, p < 0.001), THD (rs = 0.617, p = 0.003), CHD (rs = 0.580, p = 0.006), and SLVH (rs = 0.582, p = 0.006). The CHD explained 66% (R2 value of 0.660) of the variance in the ACL-RSI, while the other hop tests did not add to the predictive model. Conclusions: Physical function has the capacity to influence psychological status after ACLR. Clinicians should recognize that SLVH, SHD, THD, and CHD are correlated with ACL-RSI and improvements in physical function during rehabilitation may improve psychological status and optimize RTS after ACLR. Level of evidence: Level 3.

On-Site Evaluation of Constituent Content and Functionality of Perilla frutescens var. crispa Using Fluorescence Spectra.

Perilla frutescens leaves are hypothesized to possess antioxidant and amyloid-ß (Aß) aggregation inhibitory properties primarily due to their polyphenol-type compounds. While these bioactivities fluctuate daily, the traditional methods for quantifying constituent contents and functional properties are both laborious and impractical for immediate field assessments. To address this limitation, the present study introduces an expedient approach for on-site analysis, employing fluorescence spectra obtained through excitation light irradiation of perilla leaves. Standard analytical techniques were employed to evaluate various constituent contents (chlorophyl (Chl), total polyphenol content (TPC), total flavonoid content (TFC), and rosmarinic acid (RA)) and functional attributes (DPPH radical scavenging activity, ferric reducing antioxidant power (FRAP), oxygen radical absorbance capacity (ORAC), and Aß aggregation inhibitory activity). Correlations between the fluorescence spectra and these parameters were examined using normalized difference spectral index (NDSI), ratio spectral index (RSI), and difference spectral index (DSI) analyses. The resulting predictive model exhibited a high coefficient of determination, with R2 values equal to or greater than 0.57 for constituent contents and 0.49 for functional properties. This approach facilitates the convenient, simultaneous, and nondestructive monitoring of both the chemical constituents and the functional capabilities of perilla leaves, thereby simplifying the determination of optimal harvest times. The model derived from this method holds promise for real-time assessments, indicating its potential for the simultaneous evaluation of both constituents and functionalities in perilla leaves.

Responsiveness of the Indonesian Versions of the Anterior Cruciate Ligament-Return to Sport After Injury Score, the International Knee Documentation Committee Subjective Knee Form, and the Lysholm Score in Patients With ACL Injury.

Background: The Indonesian versions of the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI), International Knee Documentation Committee subjective knee form (IKDC), and the Lysholm scores are considered valid and reliable for Indonesian-speaking patients with anterior cruciate ligament (ACL) injury. Purpose/Hypothesis: The purpose of this study was to determine the responsiveness of the ACL-RSI, IKDC, and Lysholm scores in an Indonesian-speaking population with ACL injury. It was hypothesized that they would have good responsiveness. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Between March 1, 2021, and February 28, 2022, patients with an ACL injury at a single hospital in Indonesia were asked to complete the ACL-RSI, IKDC, and Lysholm scores before either reconstruction surgery or nonoperative treatment. At 6 months after treatment, the patients completed all 3 scores a second time, plus a global rating of change question. The distribution-based and the anchor-based methods were used to study responsiveness. For each scale, the standardized response mean, minimal clinically important difference (MCID), and minimal detectable change (MDC; at the group [MDCgr] and individual [MDCind] levels) for each scale were determined. Results: Of 80 eligible patients, 75 (93.8%) completed the study. The standardized response means for the ACL-RSI, IKDC, and Lysholm scores were 1.59, 1.72, and 1.51, respectively, indicating good responsiveness. The MCIDs for the ACL-RSI, IKDC, and Lysholm scores were 6.8, 7.8, and 4.8, respectively; all MCIDs were larger than that of the MDCgr (1.1, 0.7, and 0.6, respectively). At the individual level, the MCID for the IKDC was larger than the MDCind (7.8 vs 5.8). However, the MCIDs for ACL-RSI and Lysholm scores were smaller than those of the MDCind (6.8 vs 10.9 and 4.8 vs 5.1, respectively). Conclusion: The Indonesian ACL-RSI, IKDC, and Lysholm scores indicated good responsiveness and can be used in the follow-up of patients after ACL injury, especially at the group level. In individual patients, IKDC was found to be more efficient than the ACL-RSI or Lysholm scores for detecting clinically important changes over time after ACL treatment.

Association of Psychological Readiness to Return to Sports With Subjective Level of Return at 12 Months After ACL Reconstruction.

Background: Return-to-sports (RTS) rates after anterior cruciate ligament (ACL) reconstruction (ACLR) differ according to the level at which patients return. It is unclear whether the level of RTS is affected by psychological readiness to return. Purpose: To examine the association between psychological readiness to RTS and subjective RTS level 12 months after ACLR. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 47 patients who underwent unilateral primary ACLR surgery were enrolled. Assessments at 6 and 12 months postoperatively consisted of knee strength testing (isokinetic quadriceps and hamstring strength), the International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC-SKF), and the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale to measure psychological readiness to RTS. Patients were assigned to 1 of 3 subgroups based on their subjective assessment of RTS level at 12 months postoperatively: RTS at or above preinjury level (RTS≥Pre; n = 19), RTS below preinjury level (RTS

Video Documentation as a Measure of Written Documentation Accuracy in Emergency Medical Service Field Intubations.

Introduction: Quality improvement (QI) is a major focus of all departments and fields of health care, including emergency medical services. The chaotic and rapidly evolving atmosphere in which paramedics must practice can lead to inconsistency between what is documented and the actual events. This leads to difficulty when trying to evaluate the practitioners and when implementing a QI program. In this study, we evaluated the prevalence of discrepancy between the video and written record for Rapid Sequence Intubation (RSI) performed in the field as a demonstration of the utility of video documentation in QI. Methods: We used a systematic retrospective chart review to compare written with video documentation in 100 consecutive prehospital RSI encounters in a single EMS agency. Results: Of the patient care records (PCRs), only 6% matched the video record for all quality measures tracked. The largest reason for the discrepancy was in the time required to intubate (58%) whether LEMON was evaluated (42%), total number of intubation attempts (36%), first attempt success (24%), BVM used (18%), and whether an airway introducer device was used (12%). Conclusion: Written documentation is inaccurate compared to video documentation when used as a quality improvement process for EMS prehospital RSI encounters.
