1. Jumping patella is associated with inferior clinical outcomes after MPFL reconstruction for recurrent patellar dislocation: a retrospective cohort study.
1. 跳跃髌骨与复发性髌骨脱位MPFL重建术后较差的临床结果相关：一项回顾性队列研究PMID:日期:2026-09-04To date, two studies have established the correlation between jumping sign and multiple bony abnormalities. However, no studies have yet reported the association between the jumping sign and clinical outcomes. (1) To determine the bony risk factors of jumping patella and (2) to compare clinical outcomes between jumping and gliding patellae following medial patellofemoral ligament (MPFL) reconstruction. Between 2018 and 2022, 85 patients with recurrent patellar dislocation (RPD) who underwent MPFL reconstruction were retrospectively reviewed. Patients were stratified into two groups based on the presence or absence of the preoperative patellar jumping sign. Standard hip-knee-ankle computed tomography (CT) scans were obtained for all patients, through which lower limb torsional deformities and bony morphology were evaluated. Bony risk factors for preoperative jumping patella were identified using logistic regression analysis. Clinical outcomes were compared between groups at final follow-up. Subgroup analyses were conducted to examine outcome differences between surgical procedures within each patellar tracking group. This study included a total of 85 patients, with 36 cases in the jumping group. Multivariate regression analysis identified knee torsion (odds ratio [OR] = 7.16, 95% confidence interval [CI] = 1.64-31.33, P = 0.009) and supratrochlear bump (OR = 30.5, 95% CI = 6.95-133.77, P < 0.001) as significant factors associated with jumping patella. At the final follow-up, the jumping group demonstrated significantly lower Lysholm (75.7 versus 86.1, P = 0.002) and Kujala (80.8 versus 89.9, P = 0.003) scores compared with the gliding group. The jumping group showed significantly greater patellar medial laxity index (38% versus 22%, P = 0.001), and higher rates of residual maltracking (55.6% versus 16.3%, P < 0.001), jumping patella (27.8% versus 2%, P < 0.001), MPFL graft laxity (22.2% versus 4.1%, P = 0.01), and patellar redislocation (13.9% versus 2%, P = 0.035), compared with the gliding group. The subgroup analysis revealed that in cases of MPFL reconstruction combined with tibial tubercle transfer, the jumping patella had a much higher incidence of residual patellar maltracking (54.5% versus 15.6%, P = 0.005) and positive jumping sign (27.3% versus 0%, P = 0.002), compared with the gliding group, while no significant differences were found between the two groups in patient-reported outcome measures (PROMs), MPFL graft laxity, and patellar redislocation (all P > 0.05). Compared with the gliding patella, the jumping patella undergoing isolated MPFL reconstruction exhibited worse clinical outcomes. Although the combined procedure improved knee function and reduced redislocation rates to some extent, it could not significantly correct the persistent maltracking or jumping sign postoperatively.

2. Long-term outcomes of single-radius total knee arthroplasty in an Asian population: a comparison of cruciate-retaining and posterior-stabilized designs.
2. 亚洲人群单半径全膝关节置换术的长期疗效：后交叉韧带保留型与后稳定型设计的比较PMID:日期:2026-09-04Single-radius total knee arthroplasty (TKA) has demonstrated favorable clinical outcomes and survivorship; however, long-term comparative data between cruciate-retaining (CR) and posterior-stabilized (PS) designs within a single-radius system remain limited, particularly in Asian populations. This study aimed to evaluate the long-term clinical and radiologic outcomes and survivorship of single-radius TKA and to compare CR and PS designs in an Asian population. This retrospective study included 222 knees (152 patients) that underwent primary TKA using a single-radius prosthesis between 2006 and 2015, with a minimum follow-up of 10 years. There were 112 CR knees and 110 PS knees. Clinical outcomes were assessed using the Knee Society Score, Western Ontario and McMaster Universities Osteoarthritis Index, and Forgotten Joint Score. Radiologic outcomes were also evaluated. Kaplan-Meier survivorship analysis was performed using revision for all causes and aseptic revision as endpoints. Inverse probability of treatment weighting (IPTW) was applied to adjust for baseline differences between groups. At a mean follow-up of 13.2 ± 2.8 years, significant improvements were observed in all clinical outcomes compared with preoperative values (all p < 0.001). At the final follow-up, clinical outcomes did not differ significantly between the CR and PS groups, and IPTW-adjusted analyses also showed no statistically significant between-group differences. Revision surgery was performed in 6 of 222 knees (2.7%), with no difference between groups (p = 0.44). In the overall cohort, the 15-year Kaplan-Meier survivorship free from revision for all causes was 96.2% (95% CI 93.2-99.4). The estimated 15-year aseptic revision-free survivorship was 98.9% (95% CI 96.9-100) in the CR group and 95.6% (95% CI 91.4-100) in the PS group. Survivorship did not differ significantly between the CR and PS groups for either all-cause or aseptic revision (log-rank p = 0.99 and p = 0.99, respectively). However, only six revision events occurred, limiting the statistical power to exclude a clinically meaningful between-group difference. Single-radius TKA demonstrated favorable long-term clinical outcomes and high survivorship in an Asian population. No significant between-group differences were identified in clinical outcomes or survivorship between the CR and PS groups.

3. Long-term changes in playing time, competitive level, and market value after ACL reconstruction in elite Spanish professional football players.
PMID:日期:2026-09-04The purpose of this study was to evaluate the epidemiology and longitudinal postinjury changes in playing time, competitive level, and market value in professional male football players from Spain's First Division following anterior cruciate ligament reconstruction. This retrospective cohort study included 132 anterior cruciate ligament injuries in 115 professional football players identified between the 2010-2011 and 2023-2024 seasons using public databases (Transfermarkt and BeSoccer), with cross-validation against official medical reports or news sources. Return to play, league level, minutes played, and market value were tracked up to 5 years postinjury. Statistical analyses included chi-squared tests, repeated-measures analysis of variance (ANOVA), mixed-effects models with Dunnett-adjusted comparisons, Wilcoxon signed-rank testing, and exploratory multivariate regression analyses. The mean age at injury was 26.7 years. The return to play rate was 97.7%, with a mean return to play time of approximately 9.1 months. The first competitive appearance occurred at a median of 13.5 days after the first matchday squad inclusion. However, 35.2% of players dropped at least one competitive league level by the first postinjury season, increasing to 61.3% by the fifth season. Minutes played decreased by 46% in the first postinjury season (p < 0.001), with only partial recovery thereafter. Minutes per match played remained approximately 21 min below preinjury values during both the first and second postoperative seasons (both p < 0.001). Market value declined significantly across follow-up, reaching up to a 47.7% reduction by year 5, particularly among players aged 30 years or older. Longitudinal reductions in playing time, competitive level, and market value were observed following ACL injury in professional football players, despite high return to play (RTP) rates. Reduced minutes per match played further indicated persistent limitations in competitive utilization during the first two postoperative seasons.

4. VELYS robotic-assisted solution achieves more accurate bone cutting and neutral ground mechanical axis compared with an accelerometer-based portable navigation system in ground kinematically aligned total knee arthroplasty.
4. 与传统基于加速度计的便携式导航系统相比，VELYS机器人辅助解决方案在运动学对线全膝关节置换术中实现了更精确的骨切割和中性地面机械轴PMID:日期:2026-08-28This study aimed to compare the accuracy of bone cutting, achievement of target alignment, and early clinical outcomes between ground kinematically aligned total knee arthroplasty (KA-TKA) performed using the VELYS robotic-assisted solution (VRAS) and that performed using an accelerometer-based portable navigation system (APNS) in patients with varus osteoarthritis. This cohort study prospectively enrolled 35 consecutive patients who underwent ground KA-TKA using the VRAS and compared them with 35 consecutive patients treated with the same surgical procedure using the APNS. The primary end point was the accuracy of bone cutting and achievement of target alignment. Clinical outcomes were evaluated at 1 year postoperatively. The VRAS group demonstrated significantly smaller mean absolute errors from target values, particularly in femoral bone cutting and achievement of a neutral ground mechanical axis, compared with the APNS group (0.7 ± 0.8° versus 1.5 ± 1.1°, 1.6 ± 1.8% versus 3.0 ± 2.4%, p < 0.05, respectively). There were no significant differences in range of motion and 2011 Knee Society Score between groups. Ground KA-TKA performed using the VRAS achieved higher accuracy in bone cutting and more reliable achievement of a neutral ground mechanical axis, compared with the APNS.

5. Knee valgus proprioception, muscle activity, patient-reported outcomes and dynamic balance control after anterior cruciate ligament reconstruction: a cross-sectional case-control study.
5. 前交叉韧带重建后的膝外翻本体感觉、肌肉活动、患者报告结局和动态平衡控制：一项横断面病例对照研究PMID:日期:2026-08-20Proprioceptive deficits following anterior cruciate ligament reconstruction (ACLR) are commonly assessed using sagittal-plane, nonweight-bearing tasks that may not reflect the demands of functional activities. This study evaluated the test-retest reliability and discriminative validity of a weight-bearing knee valgus discrimination task (Knee-VEDA) and compared proprioceptive acuity, muscle activity, dynamic balance, and patient-reported outcomes between individuals with ACLR and healthy controls. Sixty-three participants (32 ACLR, 31 controls) performed the Knee-VEDA with concurrent surface electromyography (sEMG) of seven lower-limb muscles. Test-retest reliability was assessed. Dynamic balance and patient-reported outcomes were evaluated using the Y-Balance Test, International Knee Documentation Committee (IKDC) form, and Knee injury and Osteoarthritis Outcome Score (KOOS). The Knee-VEDA demonstrated acceptable-to-good test-retest reliability (ACLR ICC = 0.84; controls ICC = 0.64) and acceptable discriminative validity (AUC = 0.835, p < 0.001). The ACLR group exhibited significantly poorer proprioception in the operated limb compared with their intact limb and controls (p < 0.001). sEMG analysis revealed not statistically significant between-group differences in lower-limb muscle activity. ACLR participants also demonstrated inferior Y-Balance performance compared with controls ( = 0.02). In the ACLR group, better Knee-VEDA scores correlated with better Y-Balance ( = 0.50, p < 0.001), and better KOOS symptoms scores ( = 0.55, = 0.001). The Knee-VEDA may be a useful tool for assessing weight-bearing knee proprioception after ACLR, showing acceptable test-retest reliability and discriminative validity. After ACL reconstruction, operated-limb proprioceptive acuity was found to be reduced during the valgus task. Further validation is needed before clinical application.

6. Auditory-cued terminal knee extension enhances vastus medialis motor unit function in the early phase following ACL reconstruction: a randomized controlled trial.
6. 听觉提示终端伸膝训练促进前交叉韧带重建术后早期股内侧肌运动单位功能：一项随机对照试验PMID:日期:2026-08-14[中文摘要] 前交叉韧带重建（ACLR）术后，股内侧肌（VM）常表现出功能性缺陷，主要归因于神经肌肉改变。本研究旨在探讨终末伸膝（TKE）运动同步听觉提示对ACLR术后2周个体股内侧肌运动单位行为的即时影响。研究招募了38例初次ACLR术后2周的个体，随机分为实验组和对照组。实验组进行三组同步听觉提示的TKE运动；对照组进行相同运动但不给予听觉提示。干预前后，使用Trigno-Galileo肌电系统在伸膝过程中评估股内侧肌肌电活动、运动单位动作电位（MUAP）和运动单位放电率（MUFR）。根据数据分布情况，酌情采用参数或非参数方法分析组内和组间差异。统计显著性设定为p < 0.05。最终分析纳入20名参与者（实验组10名，对照组10名）的数据。与非提示组相比，听觉提示组MUAP峰值[12.59（IQR 17.89）µV，p = 0.043]和平均值[11.31（IQR 3.04）µV，p = 0.029]的增幅显著更大[非提示组分别为6.26（IQR 11.02）µV和2.24（IQR 9.94）µV]。此外，仅听觉提示组在干预后显示平均肌电活动[干预前：14.23（IQR 11.37）µV；干预后：17.60（IQR 20.94）µV；p = 0.007]、平均MUAP[干预前：43.07（IQR 34.30）µV；干预后：50.33（IQR 36.12）µV；p = 0.005]、MUAP峰值[干预前：55.54（IQR 50.35）µV；干预后：61.69（IQR 52.92）µV；p = 0.005]和MUFR峰值（干预前：10.50 ± 4.29 pps；干预后：12.66 ± 3.36 pps；p = 0.016）显著增加。单次同步听觉提示的TKE运动可显著增加ACLR术后2周个体股内侧肌的MUAP。这些发现可能反映了急性神经驱动增强和股内侧肌运动单位募集改善。听觉提示TKE可能代表一种在术后早期增强神经肌肉控制的潜在策略。然而，这些效应仅反映即时反应，这些适应在长期训练中的持续性仍有待确定。NCT06662955（2024年10月25日，ClinicalTrials.gov）。
[英文摘要] Following anterior cruciate ligament reconstruction (ACLR), the vastus medialis (VM) commonly exhibits functional deficits largely attributed to neuromuscular alterations. This study aimed to investigate the immediate effects of terminal knee extension (TKE) exercise synchronized with auditory cues on VM motor unit behavior in individuals 2 weeks postACLR. The study recruited 38 individuals who underwent primary ACLR 2 weeks postsurgery and they were randomly assigned to experimental or control groups. The experimental group performed three sets of TKE exercises synchronized with auditory cues; the control group performed identical exercises without auditory cues. Before and after the intervention, VM muscle activity, motor unit action potential (MUAP), and motor unit firing rate (MUFR) were assessed during knee extension using a Trigno-Galileo electromyography system. Within and between-group differences were analyzed using parametric or nonparametric methods, as appropriate, on the basis of data distribution. Statistical significance was set at p < 0.05. Data from 20 participants (10 experimental, 10 control) were included in the final analysis. The auditory-cued group demonstrated significantly greater increases in peak [12.59 (IQR 17.89) µV, p = 0.043] and average [11.31 (IQR 3.04) µV, p = 0.029] MUAP compared with the noncued group [6.26 (IQR 11.02) µV and 2.24 (IQR 9.94) µV, respectively]. Moreover, only the auditory-cued group showed significant postintervention increases in average electromyography (EMG) activity [pre: 14.23 (IQR 11.37) µV; post: 17.60 (IQR 20.94) µV; p = 0.007], average MUAP [pre: 43.07 (IQR 34.30) µV; post: 50.33 (IQR 36.12) µV; p = 0.005], peak MUAP [pre: 55.54 (IQR 50.35) µV; post: 61.69 (IQR 52.92) µV; p = 0.005], and peak MUFR (pre: 10.50 ± 4.29 pps; post: 12.66 ± 3.36 pps; p = 0.016) after the intervention. A single session of TKE exercise synchronized with auditory cues significantly increased MUAP in the VM muscle in individuals 2 weeks post-ACLR. These findings likely reflect enhanced acute neural drive and improved VM motor unit recruitment. Auditory-cued TKE may represent a potential strategy to enhance neuromuscular control during the early postoperative phase. However, these effects reflect only immediate responses, and the persistence of these adaptations with longer-term training remains to be determined.

7. Comment on "Radiological risk factors in different patterns of patellar instability".
7. 评述“不同髌骨不稳模式下的放射学危险因素”PMID:日期:2026-08-11[中文摘要] 我饶有兴致地阅读了Chouhan等人近期发表的关于不同髌骨不稳模式的影像学危险因素的文章。作者研究了单次发作、复发性和习惯性髌骨脱位表型中的滑车发育不良、胫骨结节-滑车沟（TT-TG）距离和髌骨高度。尽管这种基于表型的影像学方法解决了一个具有临床相关性的问题，但若干方法学和概念上的考量可能限制了所报道组间差异的稳健性和临床可转化性。尽管纳入了双侧病例，分析仍在膝关节层面进行，未考虑患者内聚类效应，可能夸大了统计学显著性。此外，排除接受稳定手术的患者，尤其是在单次脱位患者中，可能引入谱系偏倚和选择偏倚，夸大表型对比的表观差异。缺乏正式的观察者间和观察者内信度评估进一步限制了结果解读，尤其是考虑到TT-TG距离、髌骨高度指数和发育不良分级已知的测量变异性。所报道的单次与复发性不稳之间的TT-TG差异较小，存在大量重叠，且无置信区间、信度指标或基于阈值的分析，限制了其在当代多因素决策框架中的临床可操作性。将习惯性髌骨脱位——通常是一种具有独特且根深蒂固结构异常的发育性疾病——纳入与发作性不稳相同的比较构念中，引发了对构念效度及治疗意义外推的担忧。总之，该研究涉及一个重要临床课题，其结论可通过纳入聚类感知分析、清晰记录排除模式并报告测量可重复性以及与多因素解剖框架内临床可操作阈值相一致的TT-TG分析来进一步巩固。
[英文摘要] I read with great interest the recently published article by Chouhan et al. examining radiological risk factors across different patterns of patellar instability. The authors investigated trochlear dysplasia, tibial tubercle-trochlear groove (TT-TG) distance, and patellar height across single-episode, recurrent, and habitual patellar dislocation phenotypes. While this phenotype-based imaging approach addresses a clinically relevant question, several methodological and conceptual considerations may limit the robustness and clinical translatability of the reported between-group differences. The analysis was performed at the knee level despite inclusion of bilateral cases, without accounting for within-patient clustering, potentially inflating statistical significance. In addition, exclusion of patients who underwent stabilization procedures, particularly among single-episode dislocators, may introduce spectrum and selection bias, exaggerating apparent phenotype contrasts. The absence of formal inter- and intraobserver reliability assessment further constrains interpretation, especially given the known measurement variability of TT-TG distance, patellar height indices, and dysplasia grading. Reported TT-TG differences between single-episode and recurrent instability were small, with substantial overlap and without confidence intervals, reliability metrics, or threshold-based analyses, limiting clinical actionability within contemporary multifactorial decision frameworks. Inclusion of habitual patellar dislocation, often a developmental condition with distinct and entrenched structural abnormalities, within the same comparative construct as episodic instability raises concerns regarding construct validity and extrapolation of management implications. In conclusion, this work tackles an important clinical topic, and its conclusions could be further consolidated by incorporating cluster-aware analyses, clearly documenting exclusion patterns and reporting measurement reproducibility and TT-TG analyses aligned with clinically actionable thresholds within a multifactorial anatomical framework.

9. Biomechanical properties of an all-soft tissue quadriceps tendon autograft compared with a quadrupled semitendinosus autograft: a cadaveric study.
9. 全软组织股四头肌腱自体移植物与四股半腱肌自体移植物的生物力学特性比较：一项尸体研究PMID:日期:2026-08-07Anterior cruciate ligament (ACL) injuries are among the most frequent ligament injuries, with autograft reconstruction considered to be the gold standard treatment. The all-soft-tissue quadriceps tendon (ASTQT) autograft has gained popularity because of its favorable graft size, reliable biomechanical strength, and reduced donor site morbidity. However, graft strength depends on the preparation, fixation, and construct stiffness. Emerging techniques, such as suture tape augmentation, may further influence biomechanical outcomes. The aim of this study was to investigate the biomechanical properties of tape-augmented ASTQT construct compared with quadrupled semitendinosus construct (QST) for anterior cruciate ligament reconstruction (ACLR) using an established cadaveric biomechanical test protocol. A total of nine human cadaveric ASTQTs and 11 QSTs were obtained from the knees of body donors. For the ASTQTs, both ends were secured using a suture tape-integrated adjustable loop suspensory fixation device. For the QSTs, the semitendinosus tendons were quadrupled and attached to two adjustable loops and stitched using the buried-knot technique described by Lubowitz. Cyclic biomechanical testing was performed following an established protocol, and load-to-failure, mode of failure, and stiffness were reported. QSTs revealed a significantly higher load-to-failure (806.1 N versus 577.9 N, P < 0.001), initial (120.7 N/mm versus 93.3 N/mm, P < 0.001) and final (153.9 N/mm versus 117.1 N/mm, P = 0.001) dynamic stiffness and higher stiffness at failure (173.8 N/mm versus 120.1 N/mm, P < 0.001) compared with ASTQTs. All ASTQTs exhibited suture tape cut-through (cheese wiring) at the proximal fixation site as their mode of failure. Conversely, suture rupture was the predominant failure mode in the QST group. In an established cadaveric test setting, the QST construct exhibited higher load-to-failure and stiffness compared with the tape-augmented ASTQT construct. The consistent cheese-wiring failure at the proximal fixation site of the ASTQT indicates that the tape-tendon interface-not the substance itself-was the limiting structural element. These findings should be interpreted as construct-specific limitations of tape augmentation in degenerated tendon tissue, rather than as evidence of intrinsic inferiority of the quadriceps tendon graft.

10. Complementary roles of standing, supine, and valgus-stress whole-leg radiographs in medial open-wedge high tibial osteotomy planning: supine minimizes bias, whereas standing and valgus-stress reduce outliers.
PMID:日期:2026-08-06Accurate alignment correction is essential in medial open-wedge high tibial osteotomy (MOWHTO). However, conventional planning based on standing radiographs may not reflect postoperative intra-articular alignment changes. While differences between standing and supine radiographs have been investigated, the role of valgus-stress whole-leg radiographs in preoperative planning remains largely unexplored. This study evaluated the predictive accuracy of standing, supine, and valgus-stress whole-leg radiographs in MOWHTO planning and determined whether integrating these modalities improves alignment prediction compared with single-modality planning. This retrospective study included 71 patients who underwent MOWHTO. Preoperative standing, supine, and valgus-stress whole-leg radiographs, along with 1-year postoperative standing radiographs, were analyzed. To minimize the influence of surgical execution error and allow the analysis to focus on planning error, the achieved wedge angle was back-calculated from postoperative bony correction and reapplied to each preoperative modality to simulate the postoperative weight-bearing line ratio (Post-WBLR). Accuracy was assessed by comparing simulated and actual Post-WBLR. Multivariable regression was performed to identify predictors of actual Post-WBLR and to compare a multimodal model with the best-performing single-modality simulation. In the postoperative valgus subgroup (n = 48), supine-based simulation showed no significant difference from actual Post-WBLR (mean difference, 0.0% ± 6.9%; root mean square error [RMSE], 6.8%). In contrast, standing-based simulation underestimated alignment (-9.3% ± 7.8%; RMSE, 12.1%), whereas valgus-stress simulation overestimated it (15.2% ± 6.7%; RMSE, 16.6%). A multimodal regression model incorporating simulated Post-WBLR from standing and valgus-stress radiographs demonstrated significantly improved predictive accuracy compared with the supine-only simulation (R, 0.606 versus 0.080; RMSE, 4.5% versus 6.8%). Notably, in patients with a preoperative standing-to-supine joint line convergence angle difference (∆JLCA) ≥ 2.7°, the multimodal model significantly reduced prediction errors (absolute error: 3.2% versus 6.8%; RMSE: 4.0% versus 9.0%; all P < 0.015). Supine radiographs generally provided the most accurate single-modality basis for MOWHTO planning. Standing and valgus-stress radiographs offered complementary information, and their integration improved prediction accuracy and reduced planning outliers. While further validation is required, a stepwise planning workflow-using supine radiographs as the default modality and multimodal integration when ∆JLCA ≥ 2.7°-may serve as an exploratory framework for reducing the risk of planning-related under- or overcorrection.
